If sync to vblank is enabled in the compiz configuration, does disabling that help? If not, does Option "EnablePageFlip" "off" and/or Option "SwapbuffersWait" "off" in xorg.conf help? (Verify in Xorg.0.log that the options are taking effect) > Would it be useful to profile something anyway? sysprof or oprofile won't be useful. If none of the above helps, it might be possible to find out where compiz is blocking with something like perf, but I don't know how offhand. > BTW, I should have mentioned that I have to boot with the "noirqdebug" kernel > parameter, otherwise the kernel will sometimes disable the Radeon's IRQ saying > "irq 19: nobody cared" (the exact message is no longer in the logs). Once the > IRQ was disabled, everything still worked, but more slowly. Hmm, the radeon IRQ not working reliably might explain at least some of your symptoms. FWIW, can you also attach the dmesg output, at least the lines related to agp/drm/radeon? -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
