SOLVED: nVidia fails to load GLX library
 

nVidia drivers fail to load GLX:

I installed the nVidia drivers as per lots of instructions available, but it still wouldn't successfully load the GLX drivers, I couldn't run “glxgears” for example.

X was trying to load and run the following file:
/usr/X11R6/lib/modules/extensions/nvidia/libglx.so

For some reason that's still unclear to me, this was the wrong file for it to try to load.

The correct GLX file is located at:
/usr/X11R6/lib/modules/extensions/libglx.so
And, its just a link to libglx.so.1.0.5336 in the same directory.

I renamed the first file:
#>mv libglx.so moved.libglx.so

Now the system loads the correct file, and I can run glxgears, a few screensavers, and tuxracer!
I have a 32MB SDR GeForce256 Card, an Elsa Erazor X, and with glxgears I'm getting around 910 FPS.
