Thank you. Switching to proprietary drivers did the trick. I also upgraded to a much more recent graphics card (nvidia).
What I'm really trying to do is use the graphics card for local gnome 3 compositing for remote desktop sessions with VNC. I'm now running into a problem with GLX_EXT_texture_from_pixmap, which appears to be a known issue. Are there any plans for VirtualGL to support GLX_EXT_texture_from_pixmap?
