How to load the glx extension?

Hey folks... I installed the latest NVIDIA drivers by hand on my Gentoo box. However, there is a lot of my games and programs that die at start up and error like so:

Xlib: extension "GLX" missing on display ":0.0".

I'm confused, because the extension is installed:

Code:

$ locate libglx.so

/usr/lib64/xorg/modules/extensions/libglx.so.195.36.24

And I have a load statement inside my xorg.conf:

Code:

$ cat /etc/X11/xorg.conf

# nvidia-xconfig:  version 1.0  (buildmeister@builder58)  Thu Apr 22 20:35:23 PDT 2010

So, what did I forget here?

Did you select the nvidia opengl module with eselect?

There was only one on the list, and it was already selected. But I select it again and it made no difference:

Code:

$ eselect opengl list

Available OpenGL implementations:

  [1]  xorg-x11 *

$ eselect opengl set 1

Switching to xorg-x11 OpenGL interface... done

$ fgfs # Flight Gear Flight Simulator

Xlib:  extension "GLX" missing on display ":0.0".

Error: :0.0 has no GLX extension.

Xlib:  extension "GLX" missing on display ":0.0".

Error: :0.0 has no GLX extension.

Segmentation fault

reinstall ALL of mesa all .so and .h files
the nivdia.run installer overwrites some of them .

Well first, you would have to restart X (and maybe even reboot) after using the eselect tool. And, second, you clearly didn't install the AMD proprietary drivers properly because they would show up as a separate opengl implementation. I suggest reinstalling them again (you are emerging them and not just installing them by running the installer from AMD, right?)

adamk75 ,CoderMan is installing a nvidia driver not a ATI one

this sounds like the nvidia.run installer from the nvidia web site.

D'oh. Thanks for the correction. I usually help out with the AMD driver since that's the one I'm most familiar with. Didn't even realize I was talking about the wrong driver here.

My advice still stands, though :-) He should emerge the driver rather than using the installer from nvidia :-)
