There appears to be a bug in agpgart - there is a patch on launchpad, but I will try the following first: (from ubuntu forums) "Heres how you can get DRI and GLX working (even AIGLX) First off get to a prompt (ctrl-alt-F1) at the prompt type sudo nano /etc/X11/xorg.conf look for the modules section in there insert a # before all but load "dri" load "dbe" load "extmod" load "freetype" load "glx" Then find the section about the graphics card in there type Option "useFBdev" "false" Option "SWCursor" "true" Option "ForcePCIMode" "true" That should get you a working DRI and GLX."
