X11 or freeglut problem

[Paul]

Hi,

I've written a small demo program using OpenGL. It compiles fine, but
when I come to run it I get the following error

freeglut (./simple): OpenGL GLX extension not supported by display
':0.0'

My xorg.conf file looks like this (cut down a bit - but still with all
the configs in it)

Any ideas where the problem lies?
