When I try to load up 3d games my computer will not allow it.

The screen flashes then it comes up with this dialogue box:
Code:
Could not set videomode:
Couldn't find matching GLX visual
Please help I do not know what to do about it.

Dont know if it has anything to do with it but desktop effects wont work either they say :
Code:
Desktop effects could not be be enabled
Thanks alot in advance

what video card do you have?
results of

glxinfo | grep render

and finally, the contents of your /etc/X11/xorg.conf

There's your problem, you're using the vesa driver. You'll never get 3d accel on the vesa driver. >.<

You need to see if your card is supported by any of the community or nvidia released binary drivers.
