no glx extension

kupek85 · 08-12-2004, 04:43 PM

I recently tried to play tuxracer for the first time, but instead of getting the game, got this:

Xlib: extension "GLX" mission on display ":0.0"
***tuxracer error: Couldn't initialize video: Couldn't find matching GLX visual (Success)

I've emerged version 1.0.6111 of nvidia-glx and nvidia-kernel, and when I run "modprobe nvidia," it shows up in lsmod. The next step, from what I've gathered, is to change my xorg.conf file to read

Driver "nvidia"

Under the device section, but if when I try this and exit from X, I can't get back into X. The xorg.conf file also has "glx" uncommented and "dri" commented, like it's supposed to be. Also, I've recompiled my kernel and rebooted, so that can't be it.

Thanks in advance!

First check your X log file. It's called /var/log/X[version].0.log and contains lots of useful information for troubleshooting. Look for lines starting with (EE), indicating errors.

The file /var/log/Xorg.0.log has this important line:

(EE) Failed to initalize GLX extension (NVIDIA X driver not found)

This still doesn't make much sense to me, as the driver shows up under lsmod.

One other thing worth mentioning: my card is a Radeon 9600 Pro. Hope that helps.

Try opengl-update nvidia to change the GL libraries to nvidia's GLX.

I also had that error message on my NVidia card.
Then, I tried this command:

sh ./NVIDIA-Linux-x86-1.0-6111-pkg1.run --opengl-headers

That fixed it.

Try this it will more than likely work, though funny thing that you'd use a windows fix in windows but bare with me:

1) uninstall the nvidia driver (pretty easy just run the installer script with --uninstall)
2) re-install (using --opengl-headers)
3) change xorg.conf appropriately (as noted in Nvidia's readme file)
4a) xorg.conf, make sure nothing repeats as I have found that under the "screen" section there were some repeat values
4b) look for other duplicate values, like anything relating to DRI (comment it out) , as I have commented it out, and wine thought it was smart and added it back in for me and it has come back right next to the where I previously commented it out, how nice!
5) Go back into X, problem should be solved

Since your card is made by ATI, perhaps you should immediately get rid of the Nvidia drivers you are using and install the ones for ATI. I believe that they are available in portage. If not, you should be able to get them from the ATI site. Follow their directions carefully. Be sure to enable "DRI" and "glx" in your xorg.conf and make sure that there is a

Code:

Section "DRI"
    Mode 0666
 EndSection

as well to give users permission to use the 3d accelleration. Good luck.
