Some of the open source X11/video drivers do not support graphics
acceleration on newer cards.

For instance, I have a laptop with an ATI9600.  The open source
"radeon" driver works great for non-GLX use, and it even handles
dual-head operation.  But when starting X, it leaves a message in
/var/log/Xorg.0.log saying something like "GLX not supported on
9000 and above".

I installed ATI's proprietary "fglrx" driver and now GLX works great.

I have seen similar problems with nvidia cards and the open source
"nv" driver (which does not support dual-head).  Install nvidia's
proprietary "nvidia" driver and you get your graphix accleration
and dual-head support.
