are all videos messed up? on my setup ,it's just .wmv files that are messed upped:(

[Mr. Polite]

,wmv playback is messed up. Other formats play, but at a very low frame rate.

[bowlby]

My video was messed up too for wmv's. But changing the videodriver to opengl fixed that.

[xOrphenochx]

I haven't messed with it in a month or so, and in that time I did a large update, and installed the nvidia drivers from the site instead of the repo. Now whenever I try to start Xgl, it fails at loading glx. Simple as that.

Hi fellow Xgl users ;)

I managed to install Xgl and run compiz with this tutorial. It al works fine except some strange redraw? problems. Please look at the attached screenshot. Does anyone know how to fix this problem?

I have "the_exactly_same_problem"...but reading the following pages, :-k I didn't understand if it's possible to solve or not, and, more important, HOW!!!:confused: :confused: :confused:

I would recommend going over the steps where you edit xorg.conf again and making sure they look like they do in the examples at the beginning of this thread. Its possible that the driver installer messed them up.

[xOrphenochx]

I always keep a backup, nothing has changed. Sigh...only if it were that simple.

i had horrible video playback, but then i enable vsync and used the gl2 video engine in mplayer.
now everything works like a charm and without tearing.

I was able to switch to the gl2 video engine in mplayer. But how do I enable vsync?

[barsanuphe]

i have a nvidia card so i just had to add:

export __GL_SYNC_TO_VBLANK=1

to my /etc/init.d/gdm. dont know if this works with ati cards. if it doesnt, theres probably an equivalent.

just install the nvidia drivers from scratch..it will solve your problem

1. Ctrl+Alt+F2
2. sudo /etc/init.d/gdm stop
3. sudo apt-get remove nvidia-*
4. sudo NVIDIA-Linux-x86-1.0-8756-pkg1.run
5. sudo apt-get install linux-restricted-modules-'uname -a'
6. sudo apt-get install nvidia-glx

and let any dependencies to be installed or uninstalled
restart ur computer and u are done!

[keshav0001]

one thing more you'll have to reinstall mesa packages as nvidia drivers messes with them..and you will have your compiz working again like a charm

Install gset to configure compiz
on terminal
1. sudo apt-get install Gset-Compiz
2. gset-compiz

then disable miniwin
hope this helps

Hi fellow Xgl users ;)

I managed to install Xgl and run compiz with this tutorial. It al works fine except some strange redraw? problems. Please look at the attached screenshot. Does anyone know how to fix this problem?

Me and Aphelion asked more than once how to solve the problem...PLEASE, could anyone help us??? Just for reference the post I quoted is #15 on the second page...look at the screenshot, I really can't understand what's wrong with that...
I've read many pages (not ALL the pages) in the forum, but noboby talks about this...

[xOrphenochx]

Ok, no more GLX loading error, but it's still busted. Nothing seems to happen when I use this .Xsession like I did previous(and it worked). The xorg log shows no errors.

#!/bin/sh
# Start up Xgl, compiz, and GNOME
# Run Xgl server on :1, on top of normal X
Xgl :1 -fullscreen -ac -accel glx:pbuffer -accel xv:fbo &
# Tell subsequent X programs to access the Xgl server at :1
DISPLAY=:1
# Start Compiz window manager
gnome-window-decorator &
compiz gconf decoration wobbly fade minimize cube rotate zoom scale move resize place menu switcher &
# Start GNOME
exec gnome-session

[yusufk]

Ok, I do not learn.

Instead of forgetting about it, I went on and gave this whole compiz/Xgl thing another go.

No major breakage this time. I followed the guide up till the point where thefuture is executed. The problem is, when I do that the window titlebars disappear completely, which renders any window unusable. New windows appear on top of each other and there is no way to bring focus to the ones in the background. Don't panic. Ok, after my previous problem, I understand that there is a problem with the window manager. So, killing compiz.real and gnome-window-decorator and executing metacity from the terminal brings my system back to life.

So, the question is: why does the window manager screw up when I launch 'thefuture'?

Oh, I forgot to say: I've got a relatively old graphics card with the GeForce2 MX/MX 400 chipset, but I don't think that's the issue, since at least the driver (version 8756) seems to work fine. I firstly installed it in Breezy from the repos (can't remember which was the version back then) and then I reinstalled it in Dapper when I did the upgrade, also from the repos.

Thanks.

I use XGL when my laptop is un-docked and use a script to return to normal X when docked because I then use twinview and XGL is not working perfectly on twinview yet. Anyway, recently the window manager gnome-wm stopped loading automatically and after some scratching around I figured that it has something to do with the gnome session settings.

To cut a long story short, this fixed it:

rm .gnome2/session


Hope this helps

oh and you can open a shell as soon as you boot and type gnome-wm for a temp fix (till u reboot)

[xOrphenochx]

I tried doing a nested one and I got this, I'm sure this is the root of my problems. But alas, I haven't found a working solution to it.

[OffHand]

when I run thefuture in the terminal I get this error:

admin@dapper:~$ thefuture
admin@dapper:~$ gnome-window-decorator: Another window decorator is already running
compiz.real: GLX_EXT_texture_from_pixmap is missing
compiz.real: Failed to manage screen: 0

It kills gnome. Anyone know how to solve this?

Edit: I tried to fix it with this:
admin@dapper:~$ ln -sf /usr/lib/nvidia/libGL.so.1.2.xlibmesa usr/lib/nvidia/libGL.so.1
ln: creating symbolic link `usr/lib/nvidia/libGL.so.1' to `/usr/lib/nvidia/libGL.so.1.2.xlibmesa': No such file or directory
Like you can see that didn't work.

[Scunizi]

I need to regress here a little... I've got XGL & compiz working great with one exception. The how to's at the beginning mention using xmodmap /usr/share/xmodmap/xmodmap.us for US keyboards. When I did this I lost the ability to use /, *, -, & + from the numeric keypad... Any thoughts? or solutions?

[alingatong]

I need help running xgl+compiz in my laptop. Its a dell c840 with nvidia geforce4 440 with 32mb vram i think. It has 512 RAM and is pentium 4 2.0 ghz. I run xgl and compiz but after sometime of use (say about 20 seconds), when I maximize application windows I get a black screen when I minimize it I see the application. When I launch new apps my screen goes black only a cursor will show. When I move my cursor to the panel location, i see that the icons are slowly coming back.

Why is this? can i run xgl+compiz with this grafix card? please i need help. I wanted to have this laptop because it has an nvidia card and hoping to run xgl+compiz but everything seems not right. what can I do?

[Pausanias]

To Undo

This command:

sudo rm /etc/gdm/gdm.conf-custom





A bunch of discovered that this method of undoing xgl/compiz causes gdmsetup to segfault when it's run. Apparently in the current version GDM, there needs an /etc/gdm/gdm.conf-custom file for gdmsetup. So, the solution is to backup your old gdm.conf-custom file before using the xgl/compiz instructions, and restore it if you want to undo.

[hitman012]

I've just installed Dapper from the liveCD and followed the instructions on the first post, but unfortunately running compiz (compiz --replace or thefuture) removes the borders on all the windows that I have open, but nothing more.

I can reset this by using metacity --replace, but it is confusing that compiz refuses to work. I have seen other people with the same problem in this thread, but no real solution - does anyone have an ideas?

[Scunizi]

After running "compiz --replace gconf miniwin decoration transset wobbly fade minimize cube rotate zoom scale move resize place switcher trailfocus water" you should then run "nohup gnome-window-decorator &"... works for me.

Hi!
Sorry, my English is very bad :(
My problem: I have allready install XGL on my Ubuntu Dapper. But animation in windows is very slow, video in Totem is very slow too (specialy in fullscreen). This problem doesn't exist when Compiz is not running (when nothing in the top of the windows). Tell me, what is wrong??
And also in Tvtime (Avermedia 203) scene isn't exist – only green fake...

My video card is Nvidia Geforce 6600, drivers is ok.

PS. I'm speak Ukrainian and Russian.

[michaelharg]

Hey! I'm struggling to get XGL+Compiz set up, my graphics card is a Geforce Ti4200 8xAGP so i think i have to install Glitz, how do i do this?

I have tried "sudo apt-get install glitz" and googled around but still cant find anything.

Any help would be great... Thanks!

[hitman012]

I have tried "sudo apt-get install glitz" and googled around but still cant find anything.

Any help would be great... Thanks!
I downloaded the latest version from here (http://www.freedesktop.org/wiki/Software/glitz), extracted it and then used make to compile it. You'll need to apt-get gcc, build-essential and make before you can do that. Once they're downloaded, go to the extracted glitz directory and type "./configure", then "make" and then "make -install" once it's done without errors.

[michaelharg]

Which version did you use? The only downloads i can find are the development snapshots..

[hitman012]

I used the glitz-0.5.3.tar.gz snapshot.

[michaelharg]

I get an error message saying:
--
checking for style of include used by make... GNU
checking for gcc... gcc
checking for C compiler default output file name... configure: error: C compiler cannot create executables
See `config.log' for more details.
---

What do i do now?

[hitman012]

Did you apt-get build-essential?

[michaelharg]

No, i hadn't.

Ive done "make" and "make install" without any errors now so it should be done now. Is there any way i can check?

Should i just continue with the install as per the HOWTO in this thread?

Much thanks Matey..

[michaelharg]

I'm just going through the second part of the HOWTO and i dont have the GLcore or dri modules on my xorg.conf file. This shouldn't make a difference because they are commented out but i just want to be careful because i have allready broken one install by trying to get xgl up and running...

[hitman012]

Yep, once I'd installed I continued with the howto and it worked fine. As for GLcore and dri - I definitely didn't have GLcore but I think that I did have dri. I wouldn't worry about it.

[michaelharg]

Ive got it all up and running now, thanks very much for your help!

Java with Swing GUI can't output anything with Compiz window Manager..](*,)
Anyone have the solution??
Thanks..]

[userundefine]

OK, I've got XGL set up (thanks to the great guides here!) and working beautifully, but have a small issue. A "blank" window on the dock appears while moving between windows and I can't really identify where it comes from, and it won't go away. Anyway, when I mouseover it on the dock XGL crashes along with my window titles. I can restart it quickly with 'thefuture', but it'd be nice if there was a workaround or fix.

Has anyone else experienced this?

[Alexander Grundner]

Hey guys,

I just wanted to add that if you don't run the xmodmap line, shift+backspace will probably kill your X session. It does for me.

If you -do- run the xmodmap line, though, you won't have a lot of other shortcuts working.

"casimir" on #ubuntu-xgl offers this suggestion, which works for us (instead of running the xmodmap line):

xmodmap -e "keycode 22 = BackSpace BackSpace Terminate_Server"

The original poster of this thread might want to change that xmodmap line so no one else has the same problems.

--Jonathan Roes

Is there a quick way to make this permanent? When I reboot the changes are gone.

[xOrphenochx]

Ok, it works now, but I still have a weird mouse problem. You can see the glitch if you look in the middle of the screen, stuff like that follows my mouse when ever I move it, and it isn't static. Any idea as to how I can fix this?

Depends on the app. Eg. jEdit have the option to use swing for the window border which fixes it.

Hi troorl and welcome to the forums!

Fullscreen video playback is a generall issue in XHL and is not solved yet, because ther is no xv driver for XGL. (Direct rendering in XGL is only available to compiz, but not to applications as glxinfo will tell you....)

Therefore I suggest you to be able to run a Xorg session, in which you can watch fullscreen videos or run 3-D games.

Ther are two ways:

1. Decide at login at GDM whether to run Xorg or a fullscreen nested XGL session. (see here (https://wiki.ubuntu.com/XglHowto) ot there (http://www.ubuntuforums.org/showthread.php?t=174233))
2. Start two X-Servers: Xorg and XGL to switch between with CTRL+ALT+F(7/8) (see here (http://www.ubuntuforums.org/showpost.php?p=1035288&postcount=30))

I'm using the second method (and recommend it as you don't have to logout to run Xorg, simply switch to it.)

There is another possibility. I just tested this with my ATI/fglrx setup. Start mplayer with the following command gives me fullscreen output but not through the Xgl session.
DISPLAY=:0 gmplayer -fs -vo xv filename
I would believe the same thing is possible with an Nvidia setup.

[sciyoshi]

Hey subsonic and anyone else with GLX_EXT_texture_from_pixmap problems:

Also "Alt-wheel" and "super-wheel" do not work for transparency and zoom.

Ok. I fixed my problem. I just removed all other resolutions from the 24bit line and restarted.

[tuxcantfly]

Xgl and compiz work fine with just about everything for me; it's all nice and smooth, except with openoffice.org. For some reason, while all other apps start just as fast as normally, openoffice starts, and takes a very long time to draw its widgets, and while I scroll, it constantly pauses for a few seconds and redraws them. Removing openoffice.org-gnome and openoffice.org-gtk helped speed up the widget-drawing process, and by disabling compiz, it stops rerendering them, yet xgl still performs by far slower on openoffice.org than on standard xorg. It's not my graphics card; it's a geforce 6500, and I have all the latest drivers, and all the eye candy works fine and fast for me. I tried lots of apps, and the problem only occurs with openoffice.org. Has anybody else had this problem, and is it an issue with xgl or openoffice.org?

[Alexander Grundner]

I asked this question earlier but no one has responded. How do you make the following command permenant to resolve X rebooting when holding down both SHIFT + Backspace?

xmodmap -e "keycode 22 = BackSpace BackSpace Terminate_Server"

I tried altering keycode 22 in the xmodmap.us file, but it still had no effect.

[mcarlson]

Hmm.. I've tried this a number of times and failed.
I've read through this whole thread (and a few others) and I am not sure what my problem is so I'm finally going to ask for help in tracking it down.

I have an onboard GeForce 6100
I have installed the newest drivers (1.0-8762) using tseliots script.
I have updated my xorg.conf
I have installed xgl using the apt-get command on the first page of this howto
I created gdm.conf-custom (cut and paste from the howto)
I created thefuture, rebooted a number of times, and kept on trying...

What I get:
The dreaded "compiz.real: GLX_EXT_texture_from_pixmap is missing
compiz.real: Failed to manage screen: 0
compiz.real: No managable screens found on display :0.0"

Then my mouse stops allowing me to change window focus, and I have to clt-alt-back to get things working again.

Does anyone see what I'm doing wrong???

Thanks

[thero]

If you are using something like thefuture script to start compiz, you could add that line under the compiz start line in the file.

Hey thanks for this guide it worked like a charm for me....I have one question.

Is it possible to disable that portion and still have the rotating desktop and transparency? thanks...

Hey thanks for this guide it worked like a charm for me....I have one question. While using the xgl stuff I like the rotating cubes a lot, the transparency is ok....and the wobbing effect I dont care for at all (when programs open). Is it possible to disable that portion and still have the rotating desktop and transparency? thanks...
Incase you haven't already you can apt-get install gset-compiz and use it to customize compiz to your likes.

[smitty1276]

You said to make your xorg.conf "Device" section look exactly like yours, aside from Identifier. DoOes that include the BusID? (It seems like it couldn't but maybe I'm missing something) Mine is "PCI:2:0:0". If I change it to say "PCI:1:0:0" like yours does my X server won't start. If I don't change it then X will start but I keep getting the ...

"GLX_EX_texture_from_pixmap is missing ... Failed to manage screen: 0 ... No managable screens found on display :0.0"

... error that has been mentioned earlier.

I am running with a GeForce 6600GT AGP. What's the story with the missing extension?

[dr_d]

hi lads... sorry i'm not up to date with this thread or the status of xgl/compiz on ubuntu.

would i be correct in assuming from Nelson-Ray's post that we finally have transparency working in dapper? if so, does it work by default, or does it have to be enabled somehow?

cheers!

Everything is working...probably better than breezy

[slimsam1]

When I close a window, there is a good chance that the X server will crash. I think it might have something to do with a plugin, but even when I disabled all but gconf, it still happened. I also don't like the panel at the bottom with tiny copies of all the windows. I'd like to get rid of it. Any ideas?

[Ma_USMC]

I just wanted to post that I used a combination of this tutorial and the tutorial located here (http://compiz.net/viewtopic.php?id=652). I am now in complete amazement at how versatile this app is. Thank you to those who have taken the time to write these.

[moclippa]

Thanks a lot! This is great! Wasn't expecting it all to be this cool at all....

For your info this seems to work perfectly fine on a Toshiba Tecra Laptop... so other laptop users shouldnt have much trouble at all!

[moclippa]

By the way, this guide also fixed up some video problems I was having with my Nvidia card... so it killed two birds with one stone! I know this is beta, but I havent had much of a problem with it so far, the window wobble is not too much of a bother once you get the refresh rate right (as in the guide)

Running on Daper 6.06 like a charm :)

(Hope the Alt-Tab switcher gets fixed up though... the thumbnails arent perfectly clear for me, so sometimes it can be irritating trying to figure out what window I'm switching into....

*Another Suggested Fix* Instead of having a view of 3 windows at a time in the switcher, it would be nice to have them all laid out in small tab form... that way I know where everything is and how many Tabs its going to take to get there

[kart3r]

I've done everything right, but when i try to do thefuture it says that Gtk.blabla cannot sart display''

[moclippa]

Is it just me? Did anyone else loose functionality in DeskBar after doing this? I seem to not be able to type into it anymore :-?

compiz.real: GLX_EXT_texture_from_pixmap is missing

compiz.real: Failed to manage screen: 0
compiz.real: No managable screens found on display :0.0

Any idea's what I could do? I followed the steps exactly I think. Might something from other wm attempts before, or compmgr attemps be messing this up? Thanks. Please help.
I'm getting this same problem... and this thread is soooo HUGE that i can't find an answer anywhere near :(

[dr_d]

does anyone know how to solve the following problems?
(in order of importance)


1) vlc media player does not have a title bar when xgl/compiz is running. this means it is effectively useless and i cannot play music or watch videos

2) transparency is either not enabled or doesn't work

3) certain short cut keys dont work (i had the super key open up a terminal... while my other short cuts work, this one does not work when xgl/compiz is running)

4) gnome 'themes' do not work. for example if i set my ordinary desktop to have the clearlooks theme, the minute i fire up xgl/compiz it is lost

5) screen goes blank when shutting down. the nice ubuntu splash screen does not play in reverse any more



I know a lot of these problems are just cosmetic, and probably there is no fix as of yet for most of them, but if there are any fixes out there I'd really like to know about it. Especially for the first two issues.

Thanks!

After 2 days, I managed to get down to this problem. The reason for this to happen is because of libGL (mesa and nvidia).

How to fix it:


Reinstall the latest NVidia driver (8762) from the dapper repo. **IMPORTANT** I have try installing it using NVidia's own sh installer and it totally broke OpenGL.
Reinstall libgl1-mesa



This works for me. It seems that the dapper repo 8762 is compatible with the latest libgl1-mesa(http://xgl.compiz.info/) while NVidia's official ones don't. OR maybe, I missed something.

Now I face this problem where the compiz shortcuts won't work. Anybody got a fix for this? I'm using the latest pkg from http://xgl.compiz.info/.

[PriceChild]

Thankyou so much arctu!!!

This is sooo much cooler than anticipated and little/no performance hit on full screen games!

Love you all, Pricey

I installed this on my machine without a hitch everything rocked and I wobble till I bleed .... but installing on my wifes machine it all worked fine until I tried to run a video with mplayer, the only vo driver that works is X11 but since that doesn't resize that sucks, gl2 runs ok speed to but the whole screen flashes with white screens randomly anyone got this and can help

[katzman]

Hello; I just found about XGL this morning and found this guide, I followed it on a old media box / file server and it worked fine but when i tried it on my laptop....not so hot. When i use Xgl as the server the graphics and corrupted. Lines are staaggerd so that the pixels do not line up and you can't make heads or tails of it. I am wondering if this has anyhting to do with the latest nvidia drivers from the repos since my other linux machine has the older one still
here is a sample of the corruption:

[PriceChild]

Im' using the newer linux drivers from the repos... try reinstalling the nvidia drivers?

[katzman]

I tried reinstalling the drivers with no success. also tried connecting my laptop to a CRT monitor to see if it had anything to do with my laptop's screen but identical behaivour

in addtion I also tried using a nested XGL window to connect to a XDMCP server (both client and server using regular Xorg server) and got similar results

just before i attempt this, i need to clear something up.

i have set up dual monitors (TFT monitor as main and TV as secondary) via tseliot's excellent guide here --> http://www.ubuntuforums.org/showthread.php?t=98456&highlight=nvidia

will this effect my ability to install and use xgl/compiz???

thanks

[ViGiLnT]

I've just followed this guide and everything went well besides one thing:

The shortcuts <ctrl>-<alt>-<left> or <ctrl>-<alt>-<right> to rotate the cube doesn't work. I can use the <ctrl>-<alt> and use the mouse to rotate it but not the above command...

I already went to see if the shortcuts were assigned on the gconf-editor and they were! The transparency shortcut don't work too...

What can I do ?

On another note, I've read that dual screen with the quinn's xgl/compiz work well. Is that true ? What must I do to change to the CVS available at quinn's repos ?

Thanks.

[ViGiLnT]

Ok. I've rebooted and everything but the transparency is working like a charm :P

I've got another question... The transparency that i saw on kororaa is a plugin for compiz right ? Pressing shift and mouse wheel up and down i mean, and changing the window transparency.

If you're using the version of Compiz from the Dapper repos that feature isn't available. You can update to the latest CVS build to have it. Check out http://forum.compiz.net

[ViGiLnT]

With the "deb http://www.beerorkid.com/compiz dapper main

Change every line but the “Identifier” line to look just like mine:

Code:

Section "Device" Identifier- leave this line alone! Driver "nvidia" BusID "PCI:1:0:0" Option "RenderAccel" "true" EndSection


I just wanted to say that the busID setting is fine unless your running something like pci. Like me. The fix was easy becuase after looking at the error log I noticed I just needed to use nano and changed it to PCI:2:7:0 and now it all works fine.

BTW... in 6.06 they won't even let your screensave start and I don't have what I use often 'Always on top' Sucky...
But hey, looks cool for my friends. And it will work great for my demo at the linux seminar this september.
You may or may not want to mention that one in your howto.

Noticed some other things: Try getting you menu to unstick from the file drop down. Like in dia. Click the little arrow to remove the menu and use it in a differnet location... you can't it will get stuck there.

I have also noticed that popup windows that have no close, minimize or icon on the left, for instance when copying files in nautilus. You can't move those windows.
Quick update... you CAN move those popups wiht the ALT+Click feature. So That error is really no big deal.

[ViGiLnT]

It was really simple.

Just followed this guide and everything worked right away on my single screen setup, except for the plugins that are only available on the quinn's repository.

Then i updated my sources.list to include the quinn's repo. I added:

deb http://www.beerorkid.com/compiz dapper main
deb-src http://www.beerorkid.com/compiz dapper main

I did like it is explained on http://xgl.compiz.info/ to had those repos, the difference was that I added the "deb-src" one.

Then i did sudo apt-get update and all my compiz packages were updated to the ones on quinn's repos.

The I got xinerama working.

I did like i always do, i followed this guide (now I don't need it anymore, cause i already know how to do it, but i learned from there) - https://www.linux-magazine.com/issue/17/DualHead.pdf

Now I've got only one question.

Is it ok for me to add "thefuture" command to the startup sequence of gnome on sessions, so that i don't have to type "thefuture" every time I boot ubuntu ?

Another thing:

"xmodmap /usr/share/xmodmap/xmodmap.pt"

When i run this one now, I can't alt-tab and fade windows with alt-mouse wheel.
What does that do ? Do I need it ? I'm running xgl without doing that with no problems...

[nami]

ViGiLnT - Thanks for the info. I will give this a try tonight!

About adding "thefuture" to the startup. I DO remember reading something about it. For example, it should be added late in the startup sequence.

That's about all I remember. :)

[PriceChild]

Hmm.... it should be ok. However, i haven't... just incase my nvidia drivers are updated, i won't want it enabled always at startup just incase something goes wrong.

For example, after a kernel upgrade, i will need to reconfigure x, reinstall my nvidia drivers, which i would prefer to do in a terminal in gnome, rather than in tty1.

[Mr. Polite]

Wow, this thread is a monster.

I've tried searching but haven't seen a fix to my problem. Everything works fine, except _some_ windows like the font dialog in Inkscape, or the connect dialog in XChat don't have window controls. No minimize, no close, and the window can not be moved. This is only a problem in Inkscape, where the dialog window may be coving part of a drawing I'm working on.

Any help is appreciated.

[mayo]

Thanks for this great guide. Worked like a charm.
Although compiz doesn't seem to be ready for productive use. Where most of the apps work great (and look great) I'm experiencing a lot of graphical glitches in multimedia players (e.g. the menus are all messed up).

Hi

I am trying to follow the instructions on the first page. I got to the bit where it says type the following in the terminal

sudo apt-get install compiz xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 compiz-gnome

But when I do it says

Couldn't find package compiz

Why is this happening?

nami

[nami]

ok i got that bit working

but how do i do this?

Make sure your default color depth is 24!

Anyway, I did everything else, for the language but insteadof typing .us i typed in .uk

Is that correct?

then i did everything else restarted and everything

then i typed

thefuture over 100 times and it just breaks gnome in that i dont have any titlebar or window frame and gives me this error

compiz.real: GLS_EXT_texture_from_pixmap is missing
compiz.real: Failed to manage screen: 0
compiz.real: No managable screens found on display :0.0

Why is it not working for me?

Hey Everybody

I'm trying to follow this guide. I've got pretty fresh dapper install. nvidia 6600. I used Automatix. That's about all I've touched.

It seemed to be going fine. I followed everything to the letter. But when it came time to reboot, X wouldn't start. When I turned my computer on, it showed me this:

Couldn't open RGB-DB '/usr/share/X11/rgb'

I'm not sure if this is the extent of the problem. I did a search for this error, but couldn't find anything. Any help would be greatly appreciated.
Thanks.

[nami]

You must compile the newest CVS version of glitz to get this to work with Nvidia cards that lack Pixel Shaders (aka anything older than a 5200 FX). Hopefully this will be updated in the repository soon.

I have a GeForce 4 Ti 4200

So does this mean I have to compile the newest CVS version of glitz?

If yes, it that the reason why I break gnome each time I run "thefuture"?

PLEASE HELP - I'm dying to get this working!

I have the same card, and did not have to recompile anything. (This on a Dell P4 2.8Ghz. The only problem is that you don't get accelerated xv, which means that e.g. mplayer is quite slow.

The "thefuture" script works fine here. Also, perhaps it's just my impression, but there seems to be a speedup e.g. in Firefox redraws and rendering in general. Is this possible?

Overall, I'd say FANTASTIC JOB GUYS, even though this is still a bit alphaish quality. [Or maybe the Ti 4200 is really a bit too long in the tooth for this kind of stuff...]

Hi, thanks for your wonderful guide.

I think xgl is installed correctly, everything works. Except, when I run nvidia-settings I get the message:
ERROR: NV-CONTROL extension not found on this Display.

ERROR: Unable to determine number of NVIDIA Frame Lock Devices on ':0.0'.

Also there are some options missing. I have a xfx geforce 5500 128mb.
Do you now how I can solve this?

P.S.
Does anybody know how to add transparacy (for the terminal) in xgl/compiz?

It all seems to work very well. I have one problem though. My "Alt Gr" key does not seem to work. I suspect that it has got something to do with the xmodmap command.

Any ideas?

I followed the howto for xgl in the ubuntu wiki. When I launch compiz it results in a white screen with my only my mouse being displayed. The mouse moves and everything but I can't access anything, the screen is just white.

I'm running kubuntu (64 bit version) on an acer laptop with nvidia 7300

oh and is there any way to check if xgl is actually running? top doesn't show xgl but it doesn't show xorg either.

[ScarfaceIII]

Hi everybody!!!
I used this guide (except for the fact that I add the repo for new xgl packages) multiple times on the same PC, every time it worked well, except last time, when I installed the brand new 6.06 LTS. everything goes fine, I boot up, login, enter the Xgl session, but sometimes, when I close a window (not all the times, only sometimes!!!) seems like the X session crashes and it restarts from the login screen (like when you press Ctrl-Alt-Del). Does anyone know something about this? Could anyone help me? please! I really can't figure out what went wrong!

THANX very much!

[Hazzybo]

Hey guys. I am a amd64 user with an nvidia card, i just installed the final release of 6.06 and tried to install xlg following the howto guide on the ubuntu website. When i log out and change the session to xgl and log on, it just hangs for about 10 seconds with the curser and the default orange background before returning back to the log on screen. Help!

Hi everyone.

I am new to ubuntu (but not linux) and currently running Ubuntu 6.06. I am trying to get Xgl/compiz working but so far I've been unsuccessful. My first, and for the moment only, question is what nvidia driver is compatible with Xgl/compiz? Cause poofyhairguy says to get the nvidia driver from ubuntu repository. My driver was built using Nvidia's NVIDIA-Linux-x86-1.0-8762-pkg1.run script. Then i edited /etc/X11/xorg.conf and downloaded compiz, xserver-xgl, libgl1-mesa, libglitz-glx1 & compiz-gnome just like it says in this howto. Then i edited /etc/gdm/gdm.conf-custom accordingly and when i rebooted the X told me the following:
(EE)Failed to initialize GLX extension. Compatible NVIDIA X driver not found.
Note, i did have
Option "RenderAccel"
and
Option "Composite" "Enable"
in my xorg.conf together and separately.

So what i am doing wrong here? Any help is appriciated.

By the way, i have GeForce FX 5600. (just in case)

[double0seven]

everytime i run xgl i get a segmentation fault. but it shows no other errors, any ideas what could be wrong?

Haven't browsed the whole thread to see whether the solution I found worked, but I had this same problem pop up after messing about with my nvidia video drivers because of another problem. The solution I has was to reinstall the mesa libraries with sudo apt-get --reinstall install libgl1-mesa. It took me several hours to think of this solution so I thought I'd better mention it here for future reference.

http://www.albertomilone.eu/europeo/nvidia_scripts1.html

to install nvidia drivers 8762_32 for dapper drake 6.06

and I have added a repository to my sources.list file so I have the LATEST cvs for libglitz

deb http://xgl.compiz.info/ dapper main

What do I do now? Do I follow the guide on the first page again?

Do I need to do: sudo apt-get install nvidia-kernel-common nvidia-glx

or should I leave that out as I have already got the drivers working?

and I live in the uk so is this line accurate for uk users
xmodmap /usr/share/xmodmap/xmodmap.uk

???

Any advice will be appreciated greatly!

Thanks

nami

p.s. how do i check which kernal i have?

I've a little problem..?The command "thefuture" run the xgl but every time when I start some application the sistem crash and it return to the log-in screen...there's somethings to do?..

Hi everyone.

I am new to ubuntu (but not linux) and currently running Ubuntu 6.06. I am trying to get Xgl/compiz working but so far I've been unsuccessful. My first, and for the moment only, question is what nvidia driver is compatible with Xgl/compiz? Cause poofyhairguy says to get the nvidia driver from ubuntu repository. My driver was built using Nvidia's NVIDIA-Linux-x86-1.0-8762-pkg1.run script. Then i edited /etc/X11/xorg.conf and downloaded compiz, xserver-xgl, libgl1-mesa, libglitz-glx1 & compiz-gnome just like it says in this howto. Then i edited /etc/gdm/gdm.conf-custom accordingly and when i rebooted the X told me the following:
(EE)Failed to initialize GLX extension. Compatible NVIDIA X driver not found.
Note, i did have
Option "RenderAccel"
and
Option "Composite" "Enable"
in my xorg.conf together and separately.

So what i am doing wrong here? Any help is appriciated.

By the way, i have GeForce FX 5600. (just in case)
Try to cancel Option "Composite" "Enable"
I had this problem too and i've resolve it doing this operation...good luck...

[nami]

Im in the uk and am not sure if i am supposed to do

xmodmap /usr/share/xmodmap/xmodmap.uk
or
xmodmap /usr/share/xmodmap/xmodmap.gb

[vikking]

Okay, it doesn't work, I compiled glitz from CVS, I did sudo apt-get install nvidia-kernel-common nvidia-glx, I changed xorg.conf (there wasn't a GLcore module, is that bad?), set my depth to 24 in the xorg.conf, changed the device in that same file, I did sudo apt-get install compiz xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 compiz-gnome, changed gdm.conf-custom, made the thefuture command, and when I restarted, the X server (or gdm) wouldn't start, the screen kept blank... What am I doing wrong?
I have a GeForce4 420 Go.

[nami]

I CANT BELIEVE IT FINALY WORKED!!! I musted have reinstalled ubuntu over 20 times! lol

However, when i type "thefuture" in the terminal it says

nami@nami-desktop:~$ thefuture
nami@nami-desktop:~$ compiz.real: water: GL_ARB_fragment_program is missing

Anyone know why this happens?

nami

[kakulacis]

Haven't browsed the whole thread to see whether the solution I found worked, but I had this same problem pop up after messing about with my nvidia video drivers because of another problem. The solution I has was to reinstall the mesa libraries with sudo apt-get --reinstall install libgl1-mesa. It took me several hours to think of this solution so I thought I'd better mention it here for future reference.

Found this solution in other forum, tried to reinstall everything but no luck :-k

glxinfo says:
GLX_ARB_get_proc_address, GLX_EXT_import_context, GLX_EXT_visual_info,
GLX_EXT_visual_rating, GLX_SGI_make_current_read, GLX_SGI_swap_control,
GLX_SGI_video_sync, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer,
GLX_EXT_texture_from_pixmap :confused:

[ike]

It all seems to work very well. I have one problem though. My "Alt Gr" key does not seem to work. I suspect that it has got something to do with the xmodmap command.

Any ideas?

I think I found a solution. I changed back to swedish keyboard layout in gnome-keyboard-properties. Somehow the layout was changed to something I didn't want (think it was US)..

[nami]

try adding


deb http://xgl.compiz.info/ dapper main

to your sources.list

[varunmittal91]

I am using NVIDIA GEforce fx 5200 graphic card.
When I try running compiz in the terminal I get the following error message.

varun@edubuntu:~$ compiz.real: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.
compiz.real: No managable screens found on display :0.0

what should I do.
I am using edubuntu 6.06 LTS fina release version.

[Ska87]

I'm trying to install xgl and compiz with Quinn's packages.
I've installed all the packages that I need, I've configured xorg.conf, I've modded gdm.conf-custom to run xgl xserver, but when I load compiz and gnome-window-decorator, nothing happens No errors, but I lost only metacity that is killed.
So I've tried to view compiz script, and I've seen that it preload the libGL that it need. So I tried to launch manually that command, and I obtain this:

ska@ska-pc:~$ LD_PRELOAD=/usr/lib/nvidia/libGL.so.1.2.xlibmesa compiz.real --replace gconf
Segmentation fault


There is something wrong I think... but what?
I'm using a dapper from long time, my last fresh install was dapper flight 6, and then I've only updated the system. I haven't a fresh install of dapper final...

This is my xorg.conf, it was configured to run a old version of compiz, the 0.0.7 one, but at that time it worked.

you just need to add

deb http://www.beerorkid.com/compiz/ dapper main

to your sources.list and you will have the most uptodate packages including Quinns packages!

[codecaine]

I followed all the instructions it worked for my laptop for my desktop when I try to do the keyboard command its does nothing any suggestions?

[codecaine]

I got everything to work only thing that don't work is alt + ctrl and left mouse to rotate the desktop anybody know how I can manually config it?

[fuuma_monou]

I'm using a 32MB GeForce2 MX 400 (nVidia NV11). Compiz works fine for the most part, though video playback is slow. For some reason VLC's title bar is missing; the Dapper package seems to be buggy (keyboard shortcuts only work with the the mouse pointer over the video area). Starting aMule maxes out CPU usage, making the system unusable until I switch back to Metacity.

Guess I'll have to wait for future versions of Xgl and Compiz that work better with older cards, or just bite the bullet and get a GeForce FX5500.

[totempole]

Thanks for all the info contained in this thread, however I have come across an unusual bug (dont know if it is one yet). Right after I installed and got xgl and compiz working with my Dell E1705 (nvidia geforce 7900 GS) laptop, deskbar seems not to work. It shows in my toolbar but i cant click "into" it and type suff.
Anyone have any similar problems and any suggestions?

Thanks in advance.

[ferre]

Hi everybody!!!
I used this guide (except for the fact that I add the repo for new xgl packages) multiple times on the same PC, every time it worked well, except last time, when I installed the brand new 6.06 LTS. everything goes fine, I boot up, login, enter the Xgl session, but sometimes, when I close a window (not all the times, only sometimes!!!) seems like the X session crashes and it restarts from the login screen (like when you press Ctrl-Alt-Del). Does anyone know something about this? Could anyone help me? please! I really can't figure out what went wrong!

THANX very much!
I have the same problem...Does anyone can help we?thanks...

Hey all,
My screensaver will not activate, and I also cannot lock my screen.

Any ideas?

[smartalecks]

how would you "turn off" compiz? (using a launcher)
its a bit too heavy sometimes.

[tomasmekean]

I am a noob to ubuntu and to linux. I tried to follow this guide and now when I reboot I get this error. Failed to start the X Server (your graphical interface). It is likely that it is not set up correctly.

anyway this is where I am. and I do not know what to do but reinstall.

Please help

[TeeAhr1]

I hope this hasn't been covered upthread (it probably has :roll: ), but 114 pages looked a little daunting. Anyway, I got as far as reboot, whereupon the X server promptly puked on my carpet, leaving this (log file excerpt follows):
(EE) Failed to initialize GLX extension (compatible NVIDIA X driver not found)
Error opening security policy file /etc/X11/xserver/SecurityPolicy
(EE) xf860OpenSerial: Cannot open device /dev/wacom
no such file or directory
(EE) xf860OpenSerial: Cannot open device /dev/wacom
no such file or directory
Note: six more of that, ending with a thud:
Fatal server error:
no visual format found
I removed the gdm.conf-custom file, which got me back here. But I am flummoxed. Anyone know where to go from here? Thx in advance, as always...

[mmcmonster]

Thanks for the great tutorial. Looks great so far.

For those of you who notice that the wheel on their mouse no longer works after this, try the alternate step 5 in my post on another thread (http://www.ubuntuforums.org/showpost.php?p=1069100&postcount=5).

[nickdr]

wow this is freaking amazing, and makes me love ubuntu this much more *holds hands as far apart as can*
anyways my only problem is .wmv video playback. in totem i get sound and some video, i don't know how to describe it other then when you put your refresh rate too high and you get two of everything. i hope you guys know what i am talking about. i tried the video in other players like mplayer or vlc, but i only got audio, which is working perfectly.
is there any fix to this? all other format seem to be working, .mpg, .avi, etc etc.

[phoenix_1983]

OMG... this is amazing..

Thanks for this thread... Why get vista when you Linux looks as pretty as this...

only issue is that i can't change my desktop themes... is there a work around that someone has found??

[gullf1sk]

Ok my problem is pretty much the same. The first time i run thefuture, i get the above output. All other attempts i get this:

thefuture
gnome-window-decoraor: Another window decorator is already running
compiz.real: Failed to manage screen: 0
compiz.real: No managable screens found on display :0.0


Any idea's what I could do? I followed the steps exactly I think. Might something from other wm attempts before, or compmgr attemps be messing this up? Thanks. Please help.

OK, i got the same problem as this guy here.. It says another window decorator is already running. This is probably answered somewhere in the thread, but i gotta be somewhere next month so i dont have the time to browse through 107 pages of possible sollutions.

Does anyone know what could be causing this?

[winfree]

I have the same problem...Does anyone can help we?thanks...

Computer with XGL on GeForce4 MX 440 AGP8.
I my case, I've installed in dapper, xgl and compiz with Quinn's packages. Installed all required packages needed. I configured xorg.conf and gdm.conf-custom to run xgl xserver. Also, set up Sessions to run xgl from start up.

When I start the computer, it stops at the remote login window, scans for hosts with XDMCP, finds none and nothing else can be done, just rebooting.

What can I change to show the regular login screen.

Anyone any idea? I cannot login to dapper, had to reboot to w2k to access this forum.

[gullf1sk]

OK, i think i figured it out.
I had to add a repository.

deb http://xgl.compiz.info/ dapper main

After that i ran apt-get update.
After a while it said that some updates were available, so i updated, and viola!
It worked. I hope this will help someone with this frustrating problem!

[nami]

You might want to add this iswell:
deb http://www.beerorkid.com/compiz/ dapper main

Will give you all the latest stuff! :)

[gullf1sk]

Will do! :)
I ran in to a few crashes tho. Like when i am using VLC, after i close it, i get booted outta X, and it restarts.

[nami]

In the terminal try typing:

xmodmap /usr/share/xmodmap/xmodmap.us

the .us is your country, so if you are in the uk you will need to type:

xmodmap /usr/share/xmodmap/xmodmap.uk

Does this stop you from getting booted out?

If yes, then add it into your compiz start script so it runs each time.

[gullf1sk]

I'll give it a try.

edit: Still getting tossed out and strange behaviour of windows

[rudefyet]

just installed ubuntu and set up xgl/compiz

Noticed the opacity adjustment via alt-mouswheel isn't working

I ran gconf-editor and there isn't anything mapped to <Alt>Button4 or <Alt>Button5

Where the heck is my opacity?!

[myyr]

Hi


I did everything as mentioned in the how-to in the beginning and it works BUT....
ofcourse theres a BUT....
when i try to change the decorations the system-preferences-theme thingy gives me an error and it shows me that i have 'custom' theme WITHOUT any decorations.
the real problem is that i can't move some of the windows - usually those smaller ones like the themes -window and others also, like 'open...' -window. the colored bar above window is teher but i can't 'grab' it to move the window, also there are no controls on it eg 'close', 'minimize' etc.

and then theres the fullscreen thing - some programs can't do fullscreen anymore (like f-spot partially). there's a smallish 'window' in the upper left corner but no fullscreen....

ps. sorry it these issues heve been addressed in earlier post but over 100 pages are too much to read through...

[gullf1sk]

I get this error from time to time "No pixmap found! This can be fatal! Don't do that!"
Sometimes it just spams 10 lines of it, but xgl still works, other times i get booted from xgl back to normal X. Anyone know what causes this?

[BitTorrentBuddha]

I can't get this working for the life of me, for starters, my xorg.conf doesn't have any "dri" or "GLcore" so I ignored that, then I followed the rest of the instructions, and when trying to run thefuture, I just keep getting

compiz.real: Screen 0 on display ":0.0" already has a window manager; try using the --replace option to replace the current window manager.
compiz.real: No managable screens found on display :0.0

I've done it over 50 times and still nothing. Any suggestions, I'm really eager to play with my new video card :D .

When I run the compiz command, my gnome panels disappear, and my title bars for all windows disappear. I can no longer alt-tab or switch windows by clicking. I can no longer switch desktops. All applications continue to function otherwise as per normal (I'm typing this in a Firefox window with no title bar now).

[Jaidee]

Hello,

I've had Xgl and Compiz working on this laptop about two months ago, did a clean Dapper 6.06 install and now I'm having issues getting back to where I was in Beta 2.

I've installed the NVidia proprietary drivers, they work fine.

I've installed Xgl, and I'm booting it up as a session using the instructions from the wiki.

I've installed Compiz and the beerorkid and compiz repos, and updated everything to the latest version.

When I try and issue the command:

gnome-window-decorator &

my X just crashed and reboots. I don't know where to look for an error code. I haven't even got to replacing gconf with Compiz yet as this command causes some sort of crash.

Please help, and tell me if I'm being too vague!

[SamMessing]

I am trying to install XGL, but I am running into a simple problem:

When I try and run:
sudo apt-get install compiz xserver-xgl libgl1-mesa xserver-xorg libglitz-glx1 compiz-gnome


I get the following error:
Reading package lists... Done
Building dependency tree... Done
E: Couldn't find package compiz


anyone know how to solve this? Sorry if this is a somewhat obvious question, I am still very new to linux.

[yteh]

poofyhairguy...... thanks for the howto!!!!!

[Toe]

works perfectly for me!

thanks a lot! :)

[tsunade]

The compiz effects work for me, but i have a bug with my mouse pointer. When compiz is running, i can't see my mouse pointer :-k . If compiz is not running, the 'picture' underneath the pointer doesn't update immediately.

Also, the xmodmap changes each time on reboot.

Any suggestions? :rolleyes:

[MasterOfDisaster]

thanks for the help

[someusernoob]

Want to say thanx for the tutorial. I did it a few times now, can set it up in under 2 minutes. That's amazing, and no problems at all with it. Thumbs up (Y)

[BarfBag]

Working perfectly for me. Very clear, easy to understand instructions. THANKS! :mrgreen:

[tzyn]

Nice guide. Thats my 6. guide i tried, but I finally got it.

But I got a little problem why I can't use Xgl at all.

if I use the "switcher" with alt+tab the frame (where I normally can move the window) disappears and the whole system seems to be hanging. But I can do something in the open windows. Some things disappears (even i closed them with alt+f4). I hope you understand what I mean.

The other functions of Xgl work fine.

Someone got that problem, too?

[BarfBag]

I've run into a problem. Key shortcuts don't work at all. How do I fix this?

[Visceral Monkey]

This guide: http://chromakode.blogsome.com/2006/02/16/howto-compiz-xgl-on-ubuntu-for-the-morbidly-lazy-2/

Worked for me the first time and takes less than 5 minutes to do. Just another method for those having trouble with the other methods. Also note, I've updated using Quinns stuff and it all works fine.

[SamMessing]

I was following the installation instructions and when I got to the place right before the command:

I tried reconfiguring GDM to see if it that would get it to work, but upon rebooting it still failed to load.

What should I do?

Thanks,

[chollis888]

Thanks a ton Poofy, this is great. Only one draw back did/nt like rebooting to turn it off so here's a little how-to of my own. Trying to do my part for the community, and thought others might find this useful also.

This is a toggle script to turn the great features on and off.

Step 1:

Put this command in the terminal:

gedit toggle_compiz.bash
Step 2:
Copy this into the empty file:


#!/bin/bash
#
# Checks to see if process "compiz.real" is running.
# If it is, it will kill it.
# If it isn't, it will start it.
#
# By Ubuntu Community

if ps -A | grep -e " compiz.real$" > /dev/null; then
killall gnome-window-decorator
metacity --replace &

else
thefuture

fi
Step 3:
Now save the file to your home folder. Close gedit. Put this command in the terminal:

sudo mv toggle_compiz.bash /usr/bin/
Then this:

sudo chmod +x /usr/bin/toggle_compiz.bash
Then right click on gnome panel and add a shortcut, choose custom launcher in the menu and add:

/usr/bin/toggle_compiz.bash

in the command field. You can make a desktop launcher by right clicking on the desktop, choosing “create launcher” then use the same command.

Now each time you click on the icon compiz & XGL are toggled on/off! This is essential and its the only way around many bugs.

Useful HowTo; I've only encountered this problem:
$ thefuture
$ compiz.real: GLX_EXT_texture_from_pixmap is missing
compiz.real: Failed to manage screen: 0
compiz.real: No managable screens found on display :0.0
that I've solved by reinstalling mesa libraries with:sudo apt-get --reinstall install libgl1-mesa
Now XGL works like a charm on my Asus A6JC with Nvidia GeForce 7300 :cool:

I have a problem with alt-tab switching and minimizing, when i minimize window it just disappears, it's not killed, but it is not visible anymore (can see process in system monitor). When i try alt-tab, compiz crashes and kills all panels and toolbars. Does anyone have same issue? How i can solve it? Thanks!

[kakulacis]

Switched to miniwin instead of dock, alt+tabbing now is working, minimizing window sometimes result in notification tab (or watever it is called) going to bottom (as it should be) panel, sometimes on that other "thing" (compiz related, probably it's calld window switcher :D ). But atleast now it is working more or less. :-&

[mootchell]

I tried this and got the error:

gnome-window-decorator, Failed to load shadow images
compiz.real: No composite extension

Should I add composite to my xorg.conf?

*edit - added composite and now I get the Texture error. getting closer.

Hi, seems I have that same problem. However, I am a complete noob and I have no idea what adding a composite means. PLEASE let me know what you did, as i've been at this for a while (and i've learned a crapload) and just can't get it to work.

thanks.

Probably it means adding this:

Section "Extensions"
Option "Composite" "Enable"
EndSection

to your xorg.conf file

If your have Nvidia drivers from official site (newest one's) not from ubuntu repositories, then you probably have to do LD_PRELOAD before running xgl or make a simlink to your libGL.so*.
But in my opinion problem is in fact, that you do not even run xgl, i had the same :) Composite is build in xgl, so you probably do not need to add it in your xor.conf file.

Xgl worked since I didn't turn off my laptop: today I've turned it on and when i run thefuture script it goes back to gdm window.
Is there anyone who has the same problem??:confused: :confused: :confused:

[Sukarn]

OK, whats really annoying me is that none of this is working -

Try it out. Here are the basic key commands:

CTRL + ALT + Left/right arrow key. Switches to the new side of the cube for me.

CTRL + ALT + SHIFT + Left/Right arrow key- Takes the in focused app around cube.

CTRL + ALT + Left Click on Desktop - allows you to use the mouse to rotate cube.

F12 - uses the Expose like trick

Alt- Tab - switcher Vista-style

And on top of it, minimizing an application makes it disappear from the list of open tabs/applications on the taskbar. This is fine for Opera, as I can get it back by just clicking on the icon, that makes it open a new tab, but for other applications its a real mess.
And, 118 pages of a thread are just too much to read to solve a problem.

I added that line to the xorg.conf.. got nothing. I'm an extreme noob and i'm not sure what those other two things you said mean?

Now I'm getting a new error:

mitch@mitch-desktop:~$ thefuture
compiz.real: GLX_EXT_texture_from_pixmap is missing
compiz.real: Failed to manage screen: 0
compiz.real: No managable screens found on display :0.0

Then, abruptly, my panels dissapear and the visbile part of all windows open shrinks to about half their size.

What does it mean!?!

Same for me :) You can set "miniwin" plugin instead of "dock". Result is described in my post above, but anyway problem reappears when minimized/maximized window is closed and also in some other circumstances which probably are not random :) For a moment i thought that this proble is actual only for me :D

P.S. "compiz --replace gconf" brings windows back to life, but only until mentioned operation (minimizing or alt tabbing) :)

Well i'm also a noob :D Maybe not extreme, but noob.
All i can do is give you review of my actions, maybe something is right for you.

First of all i have latest drivers from official nvidia site, so probably this is problem why i need to do LD_PRELOAD for module i marked with red, by default xgl would use libGL.so.1, which i my situation is not right.


kakulacis@Sesks:~$ ls -l /usr/lib/libGL.so*
lrwxrwxrwx 1 root root 10 2006-06-08 07:39 /usr/lib/libGL.so -> libGL.so.1
lrwxrwxrwx 1 root root 12 2006-06-08 07:39 /usr/lib/libGL.so.1 -> libGL.so.1.2
-rwxr-xr-x 1 root root 543564 2006-06-07 21:37 /usr/lib/libGL.so.1.0.8762
-rw-r--r-- 1 root root 408688 2006-06-08 06:06 /usr/lib/libGL.so.1.2


So I:
1) added

deb http://www.beerorkid.com/compiz/ dapper main
deb http://xgl.compiz.info/ dapper main

to my /etc/apt/sources.list files
2)added authentication key

wget http://www.beerorkid.com/compiz/quinn.key.asc -O - | sudo apt-key add -

3) installed all packs:
apt-get install libglitz1 libglitz-glx1 xserver-xgl libgl1-mesa libsvg libsvg-cairo compiz compiz-gnome gset-compiz
4)
Created startup script
gedit /usr/bin/startxgl.sh

#!/bin/bash
LD_PRELOAD=/usr/lib/libGL.so.1.0.8762 /usr/bin/Xgl -fullscreen :1 -ac -br -accel glx:pbuffer -accel xv:fbo & sleep 2 &&
DISPLAY=:1
gnome-window-decorator &
compiz gconf decoration wobbly fade minimize cube rotate zoom scale move resize place menu switcher &
exec gnome-session

As you see in my situation with newest drivers i need to add LD_PRELOAD before running Xgl with libGL.so.1.0.8762, otherwise you may change that to libGL.so.1 or delete everything before Xgl command ("LD_PRELOAD=/usr/lib/libGL.so.1.0.8762" part)

chmod +x /usr/bin/startxgl.sh to make it executable

5) gedit /usr/share/xsessions/xgl.desktop to make startup choice of Xgl in login screen

Add

[Desktop Entry]
Encoding=UTF-8
Name=Xgl
Comment=Start an Xgl Session
Exec=/usr/bin/startxgl.sh
Icon=
Type=Application

Make it executable
chmod +x /usr/share/xsessions/xgl.desktop

If you made changes to xorg.conf then restart X (restarting only gdm will not be enough) or better restart pc. At login screen under sessions choose Xgl, which we created and log in, hope it works out.

Wow, thanks a lot. Only one thing. When I reboot I am brought first to the command line and from there log in and start x with the usual "startx" command.. but.. You were saying to choose Xgl, implying that i'd be in some kind of GUI. Is there any way to sart Xgl from the command line, or a way to get this thing to boot into the graphical log in screen (which i used to have)?

From there everything should work out...

THANKS again.


edit:
I thought I should include, although it was implied, that after using startx i am getting no compiz/xgl effects.
could that have something to do with this?:

E: Couldn't find package libsvg

I get that when I did all of the apt-get'ting mentioned in your post.

thanks yet again

[mootchell]

And.. here's another fun fact. When I put "startxgl.sh" into the terminal, a huge blue window appears that cannot fit on my screen. The terminal gives me this nice, compact list of errors:

You do not have login screen GUI? :O
Anyway if you are in a pure terminal, then try to run command /etc/init.d/gdm stop
then /etc/init.d/gdm start
It should automatically start login screen, what do you see when you change your session in terminal with alt+F9? Only black screen?

So very strange. I'm getting this when I put /etc/init.d/gdm start into the pure terminal...

}root@mitch-desktop:~# sudo /etc/init.d/gdm start

[fail]


What I meant by login GUI was that I do not get an interface for loging in when i reboot, all i get is a terminal login screen.. from which i have to start x. i tried putting "startxgl.sh" into it, but i got a bunch of odd errors that I don't know how to copy when in the pure terminal, if you even can..

I am extremley lost!

[m94mni]

Anyone noted that the instructions on

https://wiki.ubuntu.com/CompositeManager/Xgl

use the command

command=/usr/bin/Xgl :0 -fullscreen -ac -br -accel xv:fbo -accel glx:pbuffer -kb

That "-kb" disables XKB, and just doesn't make any sense. Shouldn't it be removed?

[kakulacis]

What I meant by login GUI was that I do not get an interface for loging in when i reboot, all i get is a terminal login screen.. from which i have to start x.
I know what you meant :)

Can your run X at all? Maybe gdm dont't start X automatically?
Then you should run startx at first, then switch from X to console with ctrl+alt+F1 to F4, then run /etc/init.d/gdm stop and /etc/init.d/gdm start. What is result then? Does login screen appear?
You can also try to add /usr/share/xsessions/xgl.desktop contenct to your /home/username/.Xsession and make ir executable chmod +x /home/username/.Xsession

.Xsession is default session, maybe starting from login screen default session result in using .Xsession contenc for session, but i do not know wether it will start up from running startx from terminal :(

You ca try http://www.tectonic.co.za/view.php?id=916 quick tutorial, maybe it will work for you.
And last, you can configure your /etc/gdm/gdm.conf-custom
Maybe something like that

[servers]
1=Xgl
[server-Xgl]
name=Xgl server
command=/usr/bin/Xgl :1 -fullscreen -ac -accel glx:pbuffer -accel xv:fbo
flexible=true

Try to find how to make working X login screen, seems like you have bunch of other misconfiguration or missing components :O

As you see nothing goes right when noob is trying to help a noob :)

[mootchell]

You ca try http://www.tectonic.co.za/view.php?id=916 quick tutorial, maybe it will work for you.


WOW, somehow, this worked. First time with it, it gave me some error and took me back to the command line, saying that "*something* is 2, should be 1. Fixing." Then i re-started X and now i'm back and it seems to be working.

I'm a bit worried as when I start X and the small window which says what in Ubuntu has loaded comes up, it stops on "window manager." Once I click it, it goes away, but I doubt that's actually fixing anything. I doubt, too, that it's hurting anything either.

I still don't get a graphical log in screen, which is just odd, but I'm a bit afraid to start messing with the /.Xsession, as i just edited it a bit during that tutorial.

Anyway, it works now, so THANKS.. I have conqured xgl!

[mootchell]

One small thing. Now that I've got it working all I can do it switch between desktops using the desktop chooser on the panel. How do I edit whatever it is I have to edit to change the settings for effects? Any tutorial or other thread (that isn't 400 pages) about that?

[mootchell]

Breakthrough. Upon restarting, x will not load. It is telling me something about the directory "/usr/bin/X11/font" and it's refcount being 2 when it should be one. I cannot paste the exact output here as I don't think you can copy from the pure terminal and paste once x (root account) starts up.

**EDIT**
I feel like I have too many problems to still be a part of this thread. Also, I was hoping I could catch more attention in a new one. So, if anyone reads this and thinks they can help me, replying here is fine but at http://ubuntuforums.org/showthread.php?p=1135701 would be preferred. Thanks!

[JoshHendo]

I installed it, and it worked for a little while.

After a little while I stopped and decided to keep it for when I was bored. When I tried it again, the bar of the terminal became transparent, and the mouse would move, but I couldn't do anything.

Anything that I should do? Thanks :)

[kvonb]

I would really like to add drop shadows ONLY to my desktop in the simplest way possible. Can this be done without all the spinning cube stuff?

Regards,

Kev :)

EDIT: Don't worry, I found a thread, tried it, and unfortunately it doesn't work with gdesklets so I dumped shadows :(

Yeah, I get that sometimes. Just keep running the command till it goes away. Even if thats like twenty times. It will eventually go away.
I have the same problem. However, this is when I try to run compiz, without any window decorator.. When I try to run gnome-window-decorator i get this:

Here is a copy of the MODULES section of my /etc/x11/xorg.conf file:

I'm still pretty new, so let me know if more information is required. What should I do to fix this? Originally it was failing w/o

Load "nvidia"

in the xorg.conf file, so I added it, but it doesn't seem to make much difference. I have also made sure that I have the latest nvidia drivers, which I do, but I am not sure if that would have made any sort of difference.

Thanks!

[fakie_flip]

Does this guide work for Xfce4 or only Gnome?

[rivethead]

Anyone know how to update this after the new Kernel upgrade that was just released? i cant seem to get mine working again after.

-Rvt

[link6502]

Wow, that went very smoothly. I think having an actual Nvidia 5200 videocard helped.

Anyway, XGL finally makes Gnome on this PIII run a WHOLE lot faster and so much more elegantly. I turned off "wobbly" because I thought it was overkill (but fun to play with for a while.) But I love how moving windows, minimizing/restoring is so much smoother. Resizing apps with complicated content (eg firefox) is still sluggish (as I expected) but not worse than before. I think scrolling is smoother, but I'm not sure.

Surprisingly mplayer works pretty well, except when the playback control window overlaps the video window. Moving the mouse over it seems to make it a little choppy too. I'm using -vo=xv.

The most unfortunate thing is that mplayer does run noticably slower :( I used to be able to run video smoothly at 1280x1024, now I have to drop down to 1024x768 to play a movie, but even then I still see some tearing in the image. Maybe playing with the refresh rate could help this? It's at 85Hz right now.

It would be nice to be able to turn off XGL when I want to play a movie. Any command to quit 'thefuture'?

Anyway, great howto. Thanks a lot!

[chakkid]

it didn't work out. I can't add this to the GNOME, and i have a NVIDIA card and everything. How do i add it again in another way?

[chakkid]

forget it. I only have to go System » Preferences » Sessions » Startup applications » click on Add and write thefuture. And there's another way to add this to the GNOME startup.:p

Good topic.;) And too good idea.:idea:

[senzapadroni]

Hi sam, set up your xorg.conf file:
- Go in the module section and erase
Load "nvidia"
- Go in the Device Section and check out that the nvidia driver is configured:
Driver "nvidia"

Don't forget to control that nvidia module is loaded; do that with
lsmod | grep nvidia
If it's not loaded you've to install correctly Nvidia drivers.

[Mikeynewbie]

Hey there just wanted to thank you thank you thank you after multiple attempts to get this going I finally got it working with your howto. Thank you so much, and keep up the good work.

[fakie_flip]

what are the video card requirements and other spec requirements for using xgl? Also, will xgl work on xfce4 using this guide?

Man I love the effects of this, but I think there should have been instructions for updating and upgrading.... ?

I found this thread to be a little more in depth and now I think Im in a lil better shape, I mean to say I think Im up to date with XGL, could you add a few things to your origional post/guide to get updates for this!

Here's the guide I later found that I then followed... Lookie Here. (http://www.compiz.net/viewtopic.php?id=652%3Cbr%20/%3E)

[sethmahoney]

Hey all, got everything working, and hey, it rocks! But, for some reason with RenderAccel enabled my system will spontaneously freeze up after a few seconds, especially if firefox is active. Anyone have any ideas for a workaround? I'm running a PCI-e GeForce 6200 TurboCache with 256mb video ram and the 8762 NVIDIA driver, if that helps.

I have a slightly serious problem here.

Everything seems to go smoothly throughout the whole process, no errors, no freezing, nothing until I get to the reboot process. I reboot my system and then I get a serious error where X Server fails to load and there is no graphical user interface waiting for me, let alone a Compiz/XGL ready system. I've been doing this on a clean Dapper 6.06 system, Intel, and with an Nvidia GeForce Go 6200.

I will post the exact text later, once I get some sleep... ](*,)
Did you get a situation like this one (http://ubuntuforums.org/showpost.php?p=1128566&postcount=1173)?

No, umm, the error says:

Couldn't open RGB_DB ' /usr/share/X11/rgb'

And then a lot of other stuff that seems unnecesary to type at the moment. This seems to happen every time that I get to a step where I have to restart, no matter the way to install Compiz+XGL. Could somebody please help me with this? If you need more info, please specify what, and I'll happily comply.

Great how-to!

a couple of minor problems. instead of

BusID "PCI:1:0:0"

i had to use

BusID "PCI:2:0:0"

i'm running a leadtek 5700le on an asus a7n8x board.

another problem, is that the keyboard commands don't seem to be working... any ideas as to why? i'm using a generic keyboard, ps/2... nothing fancy.... :edit: i've also ran the xmodmap command, no joy..
followed the instructions exactly, only change was to the busID...

[[L|eWiOn]]

Hmm ok i followed this https://help.ubuntu.com/community/CompositeManager/InstallingCompiz
and everything that follows that.. problem is cube etc are not working, nor do i know how to get this working.. the commands given in the latest section of the guide are not working... alt-tab does work however... i cannot seem to get it.. i used Method B in first guide Method A in 2nd ... dunno where to start now...](*,)

My issue is that I get the composite error, when I enable composite it crashes. Actually I 've replaced the metacity with compiz before starting gnome-window-decorator, i get the no boarder issue, if I enable the decorator it crashes again.
Plz provide me with some help here.

I'm having an annoying problem. I did not see anyone else having it, as I tried with search and looked for about ten first and few last pages of this thread:
XGL/Compiz installs fine, reboot goes fine.
When I entered the command to start Compiz, it gave me an error about composite missing or something..
I enabled the composite from xorg.conf and got an another problem when trying to start Compiz.
When I type the command to start it, it gives me some error for a second, goes too fast to be able to read it and X restarts.
What's the matter?

Edit: Oh, and I'm running Dapper with nVidia FX 5200

[tuxcantfly]

the new cvs version (I'm using quinstorm xgl and compiz-vanilla) doesn't screw up openoffice.org, but the current one does (icon rendering slows down to the point that you can see the open and save buttons being drawn). interesting. also, I found some nifty places which tell you how to run sdl and opengl apps normally with xgl running:

I'm getting an error when I boot the computer, and I'm stuck on the command line, so I'm just trying to uninstall now. This is what I'm getting.

"Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"

"yes"

"GDM: Xserver not found: /usr/local/bin/Xgl :0 :0 -fullscreen -ac -accel xv -accel glx: pbuffer -auth /var/lib/gdm/:0.Xauth -nolisten tcp vt7
Error: Command could not be executed!
Please install the X server or correct GDM configuration and restart GDM."

I've reconfigured GDM and xserver-xorg and neither has worked.

Anyone have an idea of what I should do? I don't care about getting Xgl to work, I just kinda want to be able to use the computer again.

I had similiar problem earlier. Try this:
sudo nano /etc/gdm/gdm.conf-custom
Clear everything inside it, then save (CTRL+O), and quit (CTRL+X)

sudo apt-get remove --purge gdm
Then
sudo apt-get install kdm && sudo dpkg-reconfigure kdm

Then reboot. Now you should have yourself in KDM without Compiz. If you want to have gdm back after it, you should try:
sudo apt-get install gdm && sudo apt-get remove --purge kdm && sudo dpkg-reconfigure gdm
And then reboot.

[Doovoo]

That worked! Thanks!

[turbojugend_gr]

Well, I started this all over, now I have other issues...

when I go "thefuture", I loose my window frames, and I am getting a whole load of output, the last lines of which is:

[turbojugend_gr]

Well, step by step.... I had an update yesterday and boom XGL - Compiz are Gracefully working. It is awesome!

Only little thing , I can't get the miniwin and the Dock working... When I change the order in the plugin loading I get no changes? I add the miniwin for instance yet it is not there after a minute??? Anyway it ROCKS!

[turbojugend_gr]

']I need to get help....

Are you sure you got Compiz working??? MOst propably you are wher I was, you have xgl but compiz is not working....

Try adding both the links (whereas the composer in that wiki says one of them), you should get an update notification, update everything then follow the howto for your configuration (e.g nvidia Gnome, Ati KDE AMD64,etc) as suggested by the first post and you should get it working, although I miss some plugins I am workng it gracefully despite that.

[Dragineez]

Thanx! Worked perfectly, now I can see why everyone is so excited about this technology - seriously cool.

[gurgle]

i followed the first post and now my VNC doesnt work. can someone help me?

[citizenkeith]

I ran into some issues.... first, my xorg.conf didn't have these lines:

Load "GLcore"
Load "dri"
Load "glx"

So there was nothing to comment out. Instead, I had:

Section "Module"
Load "i2c"
Load "bitmap"
Load "ddc"
Load "extmod"
Load "freetype"
Load "glx"
Load "int10"
Load "type1"
Load "vbe"
EndSection

When I rebooted, I experienced the same issue that DooVoo experienced ("Failed to start the X server..." etc). Luckily, I had backed up my old copy of xorg.conf, so I was able to delete the new one and replace it from the command line.

I had already changed gdm.conf-custom, so I decided to plow ahead and see what happened. I booted, and continued with your directions. I have Wobbly windows! :) But none of the short cuts work (Control-Alt-arrow keys, etc). I have no idea if that's related to the differences in xorg.conf.

Any ideas? I have a vGA MX4200.

[citizenkeith]

Bueller?

[Eleka]

Excuse me people if this question is before answered, but using the thread search I have not answer for it.

I installed Xgl and Compiz following all the steps and now I have a script called start_compiz wich runs compiz.

When I run it, it looks like work: my workspace switcher changes, the windows have effects when I move them .... but I have not other effects, like the pretty switcher, move windows with alt+left button of my mouse, rotate the cube (I don't know if I have any cube) ... it looks like it's some plugins loaded and others not ... is this possible?

How can I make it work? I have other Xgl/Compiz in a amd64 and it works fine ... what am I doing wrong?

Edit: I have tested more and more and I foend some useful info: if I run it without a script, executing "line to line" the compiz_start script, it works, but when I do the "xmodmap", it don't works. The Zoom (that is configured with the super button) don't work both (with and without xmodmap). How can I solutionate this?

[bocmaxima]

Man, this would be so bitchin to use if it didnt kill any sort of funtionality of my comp outside of web browsing. I cant play UT2k4 and I cant watch DVDs.

Whats the point of this, to wow people while word Processing? :p

[battletux]

<offtopic>This has to be quite possibly the longest thread in this place. </offtopic>

Ok thank you sooo much for this install went really smoothly and most features are working fine. :p =D>

For me the issue I am having is with the cube desktop switcher. It just will not work.

When I first ran 'thefuture' I had an error message about the cube plugin not working due to some dependancies, unfortunately i was too distracted by the wobble on dragging stuff to make a note of the actual error.

Since a reboot and re-run of 'thefuture' it no longer gives the dependancy error but the cube plugin just will not work. Is there a log file anywhere i can check?

Does anyone know of any way to re-install it, as i realy want to have this feature as without it i am stuck to only one workspace :(

[gotgenes]

Compiz is not playing well with gconf. When I issue the following command
gnome-window-decorator & compiz --replace gconf decoration wobbly fade minimize cube rotate zoom scale move resize place switcher &
None of the plugins seem to load, keenly noticeable by the lack of a titlebar and window decorations around the application windows, but also no wobbly or cube or any such goodness. Opening the gconf-editor, I notice there's no plugins entry in apps>compiz>general>allscreens or >screen0

Running, instead,
gnome-window-decorator & compiz --replace decoration wobbly fade minimize cube rotate zoom scale move resize place switcher &
that is, the same command, sans gconf, activates all the compiz plugins in their wondrous glory.

I followed the HOWTO step-by-step. Crossed every I, dotted every T.

Is there some way to get gconf and compiz to talk to each other? I would appreciate the help. I would also be interested to know if someone else is experiencing this problem.

Thanks in advance,
Chris

[gotgenes]

Well, I deleted the .gconf directory in my home directory, logged out, logged back in, did xmodmap and retried the command and it works; the compiz plugins now appear in gconf-editor. Perhaps there was a more elegant way to do it. I did lose some of my customizations of the desktop.

[th3t1nm4n]

Hi, thanks for this awesome guide, it was easy to follow and truely what I'd been looking for. I'm having a problem with xgl/compiz though and need some help, I aparently only have one workspace once I run it, only one workspace is visible on the applet in my gnome-panel, and the cube spinning function isn't working for me as many of the other key-features aren't.
Any ideas on making the workspaces/cube work?
Also, how do you enable the scroll-wheel transparency? I've been looking for info on that too.

[speedsix]

When I change the /etc/gdm/gdm.conf-custom file to get xgl to start on boot, the second screen of my dualhead setup starts up as the black/white hatched X screen with the X cursor instead of a second metacity display as usual. I presume this is a conflict in screen no.s? Is there a way round this?

Thanks

It sounds like the plugins aren't loading. Instead of running the thefuture script or compiz-start.py after logging in, try the following in a terminal and see if you get all the plugins to load:

Have you checked to see if those plugins loaded into gconf? Open the gconf-editor (Alt+F2, gconf-editor) and see if they are listed under Apps>compiz>plugins

If they aren't listed you'll probably need to nuke your gconf (rm -rf ~/.gconf), log out, log in, do your xmodmap command, and then enter:
gnome-window-decorator & compiz --replace gconf decoration wobbly fade minimize cube rotate zoom scale move resize place switcher &

If that still doesn't work, make sure you have the plugins in the first place by logging out, logging in, doing your xmodmap, and then entering the following in the terminal:
gnome-window-decorator & compiz --replace decoration wobbly fade minimize cube rotate zoom scale move resize place switcher &
which is the same thing, without going through gconf though.

[th3t1nm4n]

Got it working, had to update some stuff and reboot.

i added :

Option "Composite" "Enable"

at the end of xorg.conf, when i try logging in gdm, it plays the login sound and returns back to the gdm screen without actually logging in...
whats the solution ? im on a toshiba m60 laptop with nvidia 6600...
any help would be greatly appreciated. :roll:

[bill barsch]

Found this solution in other forum, tried to reinstall everything but no luck :-k

glxinfo says:
GLX_ARB_get_proc_address, GLX_EXT_import_context, GLX_EXT_visual_info,
GLX_EXT_visual_rating, GLX_SGI_make_current_read, GLX_SGI_swap_control,
GLX_SGI_video_sync, GLX_SGIX_fbconfig, GLX_SGIX_pbuffer,
GLX_EXT_texture_from_pixmap :confused:

hello!!
the libGL.so.1.2 have GLX_EXT_texture_from_pixmap and compix have to find it!
the problem is: nvidia's packages replaces libGL.so.1 (a link) with the libGL.so.1.0.8762
this "old version" of libGL.so is used to run Xgl but not the compiz...
you have to bakup libGL.so.1.2 (mesa) and libGL.so.1.0.xxxx (nvidia)
and start Xgl with:

#LD_PRELOAD=/usr/lib/backupNVIDIA/libGL.so.1.0.xxxx
#Xgl :1 -ac bla bla bla...

to run compiz you have to set this var:

#LD_PRELOAD=/usr/lib/backupMESA/libGL.so.1.2
#DISPLAY=:1 compiz gconf &

ok???
good rotates with the cube!!! hahaha

To my surprise, it worked like a charm for my ATI 9800 XT... Driver install was picture perfect too.

I haven't read the enire thread as it's very long but I came accross a totally different HOWTO on this here:

http://tazforum.thetazzone.com/viewtopic.php?t=2189

Scroll down to "Turning Up The Graphics" it would appear that this way does not affect your default gnome session but instead gives you an XGL session of it's own?

Not sure which of the 2 is best or if they are just as good as each other?

I also have not read the entire thread, I will continue to read it right after I am finished with this post, if I find my answer somewhere in this MASSIVE thread, then I'll edit this message.

I've encountered a weird problem which is the fact that I cannot press certain keys after I start up compiz.

Right now, I'm functioning with no enter key... at least, not the one most people use (the one above the Left Shift). I'm forced to use the numpad Enter key.
This was after a reboot, before the reboot when I started compiz, I could not press the 'Z' key...

Anyways, I hope there's a fix for this. :)

any chance of a installer showing up in automatix for compiz?

[jstroot]

Howdy. I've installed a few programs since runing XGL (which works fine), and I cannot see the fonts in these programs (Scorched3d and stellarium). The fonts are nothing but funky symbols, completely unreadable.

I've posted to the stellarium forum, and the other person who replied is also running XGL.

Just wondering if this is a coincidence, or if someone else has run into this problem.
