After last update compiz windows loss the borders and glxinfo hangs.

Confirming this bug, but I'm not sure if this is specific to mesa or is an X bug.

[Jacob Peddicord (jpeddicord)]

Possible workaround:

Run `sudo dexconf` to reset your xorg.conf. Restart X and try again.

If that doesn't work, open Synaptic and remove all of the nvidia drivers (sans nvidia-kernel-common) and run `sudo dexconf` again. It appears that the NVIDIA drivers and config applet somehow got installed on systems that do not even have an NVIDIA graphics chipset, and the system attempts to boot with an that driver and fails. `sudo dexconf` should reset the settings back to the default for your system.

[Adrián Chaves (gallaecio)]

Just 'sudo dexconf' and restarting X didn't worked for me. I'm removing nvidia packages right now. Is relevant that I've used EnvyNG to install de official nVidia drivers?

[Jacob Peddicord (jpeddicord)]

Adrián:

If you actually have an NVIDIA chipset, then you probably don't want to remove the NVIDIA drivers. I should have made it more clear that I'm have an Intel i945 chipset, hence my reason for removing them.

[Adrián Chaves (gallaecio)]

Thank you very much, Jacob.

I've opened Synaptic, removed all packages with nvidia in its name (and the one which ends with "nv" and seems to be relative to the X.org). When I rebooted the computer, there was no X. I wrote "sudo defconf" after login in text mode, and although it was as if anything had happen, it must have done.

Then, I installed envyng (sudo apt-get envyng-core), and as I log in and executed the command "supertuxkart" (which hadn't work for some time because of this "bug"), the funny music started, and the game menu appeared. Thanks, and I hope it to resolve the problem for everybody.

[Adrián Chaves (gallaecio)]

Even if I should have removed them, I had, it's done, and it works! I want to say that there a package relative to X-org that was installed before, and now it isn't (maybe it help others). The xserver-xorg-video-nv is not installed on my system anymore. Maybe it was the cause of my problem. I'm not programmer, so I just left the info.

Uninstalling all nvidia packages work for me.

Hello

removing nvidia modules solve this problem for me :
[url]https://bugs.launchpad.net/ubuntu/+source/mesa-utils/+bug/256021[/url]

thanks

[Ketil Vestby (ketil-vestby)]

Removing Nvidia solved the problem for me to, why are the nvidia-modules installed by default? - Am not using any chipsets from Nvidia, on any of my computers - but the nvidia drivers became installed on the two with GUI.

[Ketil Vestby (ketil-vestby)]

Since this bug is "importance: Undecided" (and I found my bugreport to be incomplete):

I use Ubuntu only, both at work and home. Got Intel chipsets on my home computers and at work. About once a day, X crashes. When it does, X try to restart several times - but do eventually give up.

The only message logged is:
Nov 30 14:24:47 lappetoppeline kernel: [ 182.810013] glxinfo[5970]: segfault at 0 ip 0804ad46 sp bfa0b1d0 error 4 in glxinfo[8048000+5000]

Intrepid has reached end of life. Are you still having this problem on 12.04 or later?
