compiz not working in ubuntu 10.04

**Dejavou42** · May 20th, 2010

Ok, so I've been trying to get compiz working in 10.04, and to no avail. When I try to run compiz --replace or compiz --replace --indirect-rendering I get the following message:

Code:

compiz (core) - Warn: No GLXFBConfig for depth 32

However as you will notice from my Xorg file I do not have any 32 bit options set just 24:

Code:

The video card that I'm using is:

Code:

myron@myron-desktop:~$ lspci | grep VGA
01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400] (rev b2)

I believe that I have the correct driver installed (I got it using the wonderful Ubuntu Hardware Drivers utility. it's the nvidia version 96 (recommended).

I appreciate any help!

lucid dont need xorg.conf by default, so rename yours
or delete it : sudo rm -f /etc/X11/xorg.conf

into synaptic, check that nvidia-current, nvidia-current-modaliases, nvidia-common, nvidia-settings are installed, then reboot

Thanks for the quick response dino99! Ok, so the only thing missing was nvidia-current. I installed that, and I renamed my xorg.conf. That seemed to change things up a bit. I still can't enable compiz, but I'm getting a different error now:

Code:

myron@myron-desktop:~$ compiz --replace
Xlib:  extension "GLX" missing on display ":0.0".
compiz (core) - Fatal: Root visual is not a GL visual
compiz (core) - Error: Failed to manage screen: 0
compiz (core) - Fatal: No manageable screens found on display :0.0

I also have the output of glxinfo for reference:

Code:

myron@myron-desktop:~$ glxinfo

I found some other posts that said to add some settings to xorg.conf, but I can't do this because as you said before, lucid does not use an xorg.conf file by default.

I think I have this figured out. I'll mark it as solved as soon as I make sure... To fix the "Xlib: extension "GLX" missing on display ":0.0" error message, I ran sudo nvidia-xconfig, which generated a new xorg.conf file. That brought me back to the same problem I had to begin with: "compiz (core) - Warn: No GLXFBConfig for depth 32." To fix this problem, I found that I needed to add some lines to my xorg.conf file:

If there is a module section, add: " load "glx" " to that section. If there is not a module section, just copy and paste this to the bottom of your xorg.conf file.

Code:

ection "Module"
	Load "glx"
EndSection

Also, I found that I needed to add some lines to the screen section:

Code:

	Option "AddARGBGLXVisuals" "True"
	Option "DisableGLXRootClipping" "True"

The previous two lines are actually what fixed the 32 bit depth error message.

At this point I was able to enable compiz, but all of the settings did not work, and they wouldn't save.

I found, from this thread, that I had a package missing that compiz needed. it was :

compiz-fusion-plugins-extra

I also found a helpful list of other packages that compiz needed. (I already had the rest of these installed)

compiz compiz-plugins compiz-gnome compiz-core compiz-fusion-plugins-main compiz-fusion-plugins-extra compizconfig-backend-gconf compizconfig-settings-manager

Last but not least, I found a nice tool here, that will check if compiz is able to run on your system.

I hope this info is helpful to someone else too!

You also get the error,
"compiz (core) - Warn: No GLXFBConfig for depth 32"

if you have this environment variable set.
export XLIB_SKIP_ARGB_VISUALS=1

I had set export XLIB_SKIP_ARGB_VISUALS=1 globally because I had a program that didn't play nice with compiz. Then the next day when I started my computer compiz would not work. After much searching I found out that setting export XLIB_SKIP_ARGB_VISUALS=1 caused the problem.

I removed export XLIB_SKIP_ARGB_VISUALS=1 from my .profile and added it to the script that starts the program that doesn't play nice with compiz. Problem solved!
