Make sure that you have the ATI driver loaded correctly. Run 'fglxinfo', if you see Mesa 3D or anything other than ATI. It should look like this:
display: :0.0 screen: 0 OpenGL vendor string: ATI Technologies Inc. OpenGL renderer string: Generic OpenGL version string: 2.0.6011 (8.28.8) If fglrxinfo doesn't show ATI, and you have the fglrx module loaded ( lsmod | grep fglrx ) then you may have the mtrr problem on Bug 3598 [https://launchpad.net/distros/ubuntu/+source/usplash/+bug/3598]. Run 'cat /proc/mtrr', if you see RAM numbers in the Terrabyte range, then you likely have the mtrr error. -- cant run fgl_glxgears https://launchpad.net/bugs/22373 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
