After thinking a little about that line here: "(EE) intel(0): Failed to set tiling on front buffer: rejected by kernel"
I remembered that I manually added some proposed lines to my xorg.conf that I read about in a Howto dealing with that Intel driver performance loss: Section "Device" Identifier "Configured Video Device" Option "AccelMethod" "uxa" Option "EXAOptimizeMigration" "true" Option "MigrationHeuristic" "greedy" Option "Tiling" "true" EndSection I will remove them and see if that changes anything. Anyone else added some/all of these lines? -- Clocksource tsc unstable leads to lockups in Ubuntu Jaunty https://bugs.launchpad.net/bugs/355155 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
