If you are using the drivers from NVidia you have to include the line:
Option "AllowGLXWithComposite" "true"

hardware acceleration, or something like that. You may need the latest
nVidia drivers to use that option, or at least somewhat stably. I'm not
sure. I also have the option:
Option "RenderAccel" "on"
in there as well, but I don't know enough to know why I did that.
Probably copying someone else's xorg.conf. ;-)
But I know that first option is required.
These lines are right under the line:
This seemed to work for me.
