I’m having problems with my video card in openSUSE 13.1.
I have a NVIDIA GeForce GT 630 and in the first day that I installed the drivers, everything worked perfectly until I installed steam and played some games.
But after that I was some time without playing and in the meantime I remember that there was an update from NVIDIA.
And today when I try to play, a GLX error appeared:
“OpenGL GLX extention not suported by display”
I entered the “NVIDIA X Server Settings” and I went in the “OpenGL / GLX Information” tab and the following message appears:
Please uninstall all nvidia packages and only install the G03 driver:
nvidia-gfxG03-kmp-desktop, x11-video-nvidiaG03, nvidia-glG03, nvidia-computeG03
Then it should work again.
Result:
(1/1) Installing: Mesa-demo-x-8.1.0-4.1.2 …[done]
:~>glxinfo | grep render
Error: unable to open display
I suppose you ran that as root, did you?
You have to run this inside the graphical session in a terminal window as normal user. Otherwise it won’t find the graphical display.
But it doesn’t really matter any more. The reason for your problem is obvious already.
