Maximum Texture Size Error - Compiz

[neonitron]

Hey guys / girls,

Just wondering if anyone has come up for a fix for the Compiz Desktop Effects Maximum Texture Size Issue. Here is my configuration:

- 2 Monitors, Left one set at 1280 x 800, Right one set at 1280 x 1024
- Ubuntu Intrepid 8.10
- Latest Compiz and (I believe all required dependencies)

Problem that's happening is if I try to enable Desktop effects it fails and says that my Maximum Texture Size is 2048 therefore it fails to start. Now I can modify the compiz wrapper to skip past the failure and start compiz, but if I do that then the right hand side of my screen appears as if it is all wonky and doesn't display anything properly. It just appears that after the 2048 pixel width on the right the screen won't display properly.

I know this can be done because I've done it with Windows XP, so there is no hardware issues. Just wondering what else I can try.

Laptop - IBM T61, with Intel 965GM Video .

I've tried a couple suggestions of modifying my compiz wrapper, changing my display settings, modifying my xorg.conf but nothing seems to work properly.

If I use my displays without desktop effects then it works fine. But how can I live without desktop effects! Also, if I lower my screen resolution so that the max width is less than 2048 for both screens then it works fine. But c'mon now, I want my appropriate screen resolutions! lol

And when I try to run Compiz this is the error that I get:

How can I increase my Maximum 3D Texture Size?

[zoldiel]

I have the same set up as you and have had this issue as long as I've used compiz. Since compiz renders the entire desktop as one texture you are limited by your video adapter's texture size, and as far as I know there isn't much you can do about that aside from upgrading your video adapter.

However, as a somewhat awkward workaround you could set your display settings so that one is above the other, rather than to the left or right. This will give you a total desktop size of 1280x1824, thus within your hardware's limits. I tried this for a little while but just couldn't get used to moving things up or down to get them to the monitor on the left or right.

I don't really foresee a solution to this problem any time soon. I tested dual monitor support for the Jaunty Beta tonight, and while support does seem a bit better since the last time I've used it (I actually didn't have to manually configure xorg this time), the compiz texture size issue still remains. I suppose it may be possible to develop a way to use a different texture for each display, but I don't know how much effort that would take, it could be a significant rewrite of compiz or perhaps not even possible at all. It may not even be worth the effort since newer hardware will continue to support higher texture resolutions.

Seems we are stuck for the time being.

[Sergiu Bivol]

I have exactly the same setup as the first post says, but I can use dual-head with Compiz, with the commands


xrandr --output LVDS --mode 1280x800
xrandr --output VGA --mode 1280x1024
xrandr --output VGA --right-of LVDS

Graphics: Intel Corporation Mobile GM965/GL960
Everything works well, but only if Compiz is started before setting up dual-head. If I try to start Compiz after that, it complains:

Checking screen 1Comparing resolution (2560x1024) to maximum 3D texture size (2048): Failed.

Does anybody have any idea why? I am pretty sure that Compiz is broken (stupid, I mean). There is no such limit ( 2048 ) on GM965. It used to be on older Intel boards, but not on this one.

[zoldiel]

Looks to be a bug in mesa actually, see this bug report:

https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/146298

[Sergiu Bivol]

It is a bug in mesa, indeed. However, Compiz does work perfectly if dual-head is configured after starting Compiz (my current setup is 2560x1024).
This proves that it's possible to have Compiz working above 2048, and I actually have two different cubes (one on each screen), rain effects, and Expo spanning on both screens.
Compiz coupled with KDE 4.2 is stunning...
I think it would be possible to edit the compiz script, so that it skips this check. I'll try that and report back.

[Sergiu Bivol]

Yep, it works :)

Edit /usr/bin/compiz, find the function "check_texture_size()" and comment out the line that says "return 1;".

Now, I have dual-head set up in xorg.conf and Compiz starts normally.

[zoldiel]

Yep, also you can add SKIP_CHECKS=yes to ~/.config/compiz/compiz-manager to bypass the error, however with GNOME the desktop will only extend to the 2048 point, leaving a black area on the second screen. I haven't tried it with KDE, I suppose it handles the desktop differently so that isn't an issue.

[PePas]

No, Gnome can display it fine. I upgraded my mesa package from here:
https://edge.launchpad.net/~cavedon/+archive/ppa
No I have compiz working with a proper desktop background and a full functioning desktop with icons on a virtual screen bigger than 2048.

[bobince]

Great! Ludovico's fix also works fine on my GMA X4500HD.

[drewsus]

Anyone know what to do in Lucid? That PPA only goes up to Jaunty.

This is the message I am getting:

compiz (core) - Warn: Exceeded max texture size

Launching fallback window manager

[SmSpillaz]

Anyone know what to do in Lucid? That PPA only goes up to Jaunty.

This is the message I am getting:

Use fewer screens or a lower screen resolution.

We have a plugin in 0.9.0 which fixes this btw.

[drewsus]

Use fewer screens or a lower screen resolution.

We have a plugin in 0.9.0 which fixes this btw.

its not that I am requesting to use a large screen resolution. This is the default. When I run 'xrandr -q' (which means query) then it not only polls my hardware, but also sets up the dualscreen with default settings. How should I go about changing my external monitors preferred resolution permanently?

Furthermore, who is 'we' and version 0.9.0 of what? Where can I get this plugin? What does it do?

[edit]
just found your wordpress blog and as I suspected v0.9.0 is in reference to compiz++. So, how can I go about getting version 0.9.0? Is there a ppa? This fix would make my life loads easier haha

In about a week - number of assignments pending.

[drewsus]

I can understand! Sounds great, and I cannot wait!

[thewump]

I'm not understanding this all clearly. I had things working fine on 9.10 with dual 2048x1152 displays with nvidia GeForce 7600 GS. I've upgraded do Lucid and get

compiz (core) - Warn: Exceeded max texture size

As it worked on 9.10 I'm assuming that it can work again? I haven't been able to apply the work arounds that I see here like telling compiz not to do checks..

Thanks in advance.

SKIP_CHECKS=yes only relates to skipping checks done by the ubuntu compiz wrapper script. This is only useful if your hardware has been blacklisted or is not on the whitelist (like nouveau).

That error comes from the compiz executable itself (to which checks cannot be skipped, since if any one of them fails, it would be impossible for compiz to continue, since it would not be able to create textures of that size).

Just wait for 0.9.0 - I am just finishing the code cleanup and buildsystem changes, but I just installed it on fedora 13 with nouveau and it works great. There are a few administration things to get through (like packaging, release announcements, documentation, etc) that we need to get through, but all of this is rather trivial. I predict next week (hopefully)

[thewump]

When you say "wait for 0.9.0" should I just wait for updates to find it, or can I find it elsewhere?

Thanks

[aussieoddsocks]

Just wondering what the status is on compiz 0.90 packages being available for Lucid? I'm happy to test it out on an ATI setup with dual screens that currently hits the maximum texture size error regardless of screen position. (i.e. two screens side by side or two screens top and bottom).
Currently my screen res are both set to what they natively support (1280*1024). Reducing the res enables me to run compiz plus dual screens as long as I am running a virtual screen > 2048*2048.

[illmatic]

i got exactly the same problem :).
Will the next compiz version surly solve this problem?

[dernsber]

Agreed.

I'm having this issue on a fresh install of Ubuntu 10.04 (Dell Optiplex 755, default video) Basically, Compiz works fine single monitor, but not dual. I want dual monitors and pretty effects. (mainly true transparent Terminal window)

Is this new Compiz++ being released soon?

Can I get it added to my repository's?

Or is their a configuration file i can change to ignore this error?


Intel G31/G33/Q33/Q35 video... not sure anymore than that.


Edit: Found the installer for 0.9.0, trying now. Will update if works.
