SOLVED, GO TO BOTTOM OF THREAD!

I have run the nvidia driver and followed the prompts and completed the install setup. Rebooted into GUI and tried to run glxgears as I have been advised to - and I am trying to check the performance but I get the error:

root@holly-desktop:~# glxgears
Xlib: extension "GLX" missing on display ":0.0".
glxgears: Error: couldn't get an RGB, Double-buffered visual.
root@holly-desktop:~#


I have checked the documentation from nvidia and this tells me to replace (in xorg.conf):

Driver "vesa"

with

Driver "nvidia";

I then reboot and my system shows:
'...Starting X Session'

but then my linux box hangs. Booting into Mandriva2006 I replace 'nvidia' with 'vesa' in my slackware11 '/etc/X11/xorg.cong' partition and I can reboot into slackware11 OK.

My video card is a nvidia 32MB card.

I'm running slack11

Hello there
We might need some more information like:

What videocard do you have (output of lspci -v | grep -i vga) ?
What driver version are you using?
What's the output of glxinfo | grep direct (whilst running X)?

It may be related to the driver version that you are using, as mentioned by raska. From what you have posted in relation to your video card being 32 MB, this would not be supported with the newer version of the Nvidia driver. Is this an original GeForce 256 in your computer? If this is the case, you will have to download the legacy driver for Linux from Nvidia's site. Just one possibility.

Have a look at the documentation and make sure you've got this part right as well:

Remove the following lines:

Load "dri"
Load "GLCore"

In the Module section of the file, add the line (if it does not already exist):

Load "glx"

I had the same problem. You need to revert to the (beta) 9626 driver.

Edit: Thread at the nVidia forums.

Edit2: Get the driver here:
http://www.nvidia.com/object/linux_d..._1.0-9626.html
It's titled "NVIDIA Quadro Plex Driver", but it's just the regular Linux x86 driver. It's working fine for me (GeForce4 Go 4200).

SOLVED:


This worked on my nvidia graphics card:
VGA compatible controller: nVidia Corporation NV11 [GeForce2 MX/MX 400].

Thanks to all replies.
