[fglrx] Compiz (opengl) - Fatal: glXQueryExtensionsString is NULL for screen 0

I think this is the same issue as bug 1054724. And both are a side-effect of the fix for bug 944653.

Status changed to 'Confirmed' because the bug affects multiple users.

Do we need a stacktrace to be sure?

No stacktrace required. The error message explains it all; why compiz won't start.

I am also experiencing this. AMD64/ATI Radeon HD 46xx, upgraded from precise via the software centre.

Have purged compiz configuration and reinstalled to no effect.

Actually we do need a little more info.

Hi, quick update to my original comment; removing/purging fglrx at least lets unity start. Poss bug with ATI driver?

Final update; installing fresh FGLRX from ATI page failed to solve issue.

> installing fresh FGLRX from ATI page failed to solve issue
1. http://support.amd.com/us/gpudownload/linux/legacy/Pages/legacy-radeon_linux.aspx
fglrx 8.97 (Catalyst 12.6 Legacy) support legacy hardware (pre-HD5000) but doesn't support xserver 1.13 so it can not work on Quantal.
2. http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx
fglrx 9.00 published on AMD web-site (Catalyst 12.9 Beta, August build) is doesn't support xserver 1.13 so it can not work on Quantal. It also doesn't support legacy hardware.
3. https://launchpad.net/ubuntu/+source/fglrx-installer
fglrx 9.00 published in Ubuntu repository (September build) is support xserver 1.13 but it doesn't support Radeon HD 46xx so you can not use this driver on Quantal.

So in my opinion you most likely experience different issue. Solution is: uninstall proprietary driver or use proprietary driver on Precise.

Yesterday I upgraded the system and came the same error, unity and compiz does't work. I uninstalling fglrx and now my screen does't work anymore, everything is black. I listening the ubuntu initial sound, but my screen still black. Because of this problem I thinking if I install 12.04 or change distribution to another. None of the solutions presented solved, only worsened. Ubuntu 12.10 + ATI 46xx does't work.

Same to me on NVIDIA Geforce GTX 660M. Background image appears, and Unity fails.
Ubuntu 12.10.

ubuntu13.04 is also affected

Same problem with ubuntu 13.04 using a ATI Radeon HD 7730M.
After installing the 13.3 beta driver (http://support.amd.com/us/kbarticles/Pages/AMDCatalyst13-3LINBetaDriver.aspx) I got the same error in Xorg.0.log as http://forums.gentoo.org/viewtopic-t-949372-start-0.html:

fglrx(0): Failed to allocate caches, disabling RENDER acceleration
fglrx(0): [intel] Failed to allocate video resources for front buffer 1920x1080 at depth 24
Fatal server error:
failed to create screen resources

Same here with NVIDIA GeForce 9300M GS and Ubuntu 12.10.

Found a fix for my problem and it now working.

Overview of my problem:
Ubuntu 12.10 + NVIDIA GeForce 9300 GS
Unity do not start Ubuntu 12.10 + Compiz (opengl) - Fatal: glXQueryExtensionsString is NULL for screen 0

What I did to solve this issue:
re-installed the nvidia drivers following this tutorial: http://www.dedoimedo.com/computers/ubuntu-quetzal-nvidia.html

   sudo apt-get install build-essential linux-source
   uname-r
   sudo apt-get install linux-headers-`uname -r`
   sudo apt-get install nvidia-current
   sudo /sbin/lsmod | grep nvidia
no nvidia found, so:
   sudo depmod -a
   sudo modprobe nvidia_current
   sudo /sbin/lsmod | grep nvidia
now it is ok, with count 0
   sudo /etc/init.d/lightdm restart

unity is restored! yay!

Hope this helps someone.

I'd like to thank my younger self for helping me.

After an update, something went a little kaka and the previously reported problem resurfaced.

All I had to do was follow my own previous post and after I re-installed the "linux-headers-XXX" everything went back to normal.

J

It seems that every single time I update and reboot, I have this problem. Not funny at all!

The solution is to "sudo apt-get install linux-headers-'uname -r'.

When I do that it seems that the package is not installed. Was it removed on the update?? After installing everything is back to normal.

How can we permanently solve this issue?

I just experienced this issue AGAIN and solved it as mentioned in a previous post.
