Please note, I have more or less the same graphics setup (Dell Optiplex 520 with and identical problems. Since upgrading from Feisty to Gutsy I notice that window redraws were happening very slowly. Following all the above instructions leads to similar results with one exception: glxgears crashes the Xserver (nothing interesting in the Xorg.0.log file).
I tried deleting Xorg.conf and reconfiguring with dpkg-reconfigure in case something in old xorg.conf was causing it, but no joy. -- glxinfo: 'Direct rendering: no' on 915GM video chipset on Gutsy https://bugs.launchpad.net/bugs/154104 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
