I used oprofile to get a profile of what was consuming the most CPU cycles - I ran oprofile for a short time and just let the machine "sit idle" (although it wasn't actually idle at all, as the results show).
Also, I was using the oprofile GUI oprof_start, and it reported what seemed to me like a very large number of interrupts taking place initially, although that settled down a bit after a few seconds. There was no hard drive activity which could have caused that. Workaround: Downgrade to the following packages (I got them from koji) glx-utils-7.8.1-8.fc13.i686 mesa-dri-drivers-7.8.1-8.fc13.i686 mesa-libGL-7.8.1-8.fc13.i686 mesa-libGLU-7.8.1-8.fc13.i686 mesa-libOSMesa-7.8.1-8.fc13.i686 xorg-x11-drv-evdev-2.4.0-2.fc13.i686 xorg-x11-drv-intel-2.11.0-3.fc13.i686 xorg-x11-drv-synaptics-1.2.2-6.fc13.i686 xorg-x11-server-Xorg-1.8.0-17.fc13.i686 xorg-x11-server-common-1.8.0-17.fc13.i686 Thank you for your bug report. Your issue is already known, therefore I'm closing this bug as a duplicate. However, your additional logs might help debugging the issue, so thank you for attaching those. *** This bug has been marked as a duplicate of bug 640375 *** |
Created attachment 456697 [details] dmesg output Description of problem: I tried to enable desktop effects in KDE and KDE instantly disabled them, saying they were too slow. I turned off functionality checks and re-enabled them. kwin then becomes extremely slow (and so do desktop effects). I think desktop effects should work, because 3D hardware acceleration seems to be enabled. Version-Release number of selected component (if applicable): kdebase-workspace-4.5.2-3.fc14.i686 How reproducible: Always Steps to Reproduce: 1. Fedora menu -> Computer -> System settings -> Desktop effects 2. Enable desktop effects and disable functionality checks in Advanced (leave all other options at their defaults) Actual results: kwin very slow (uses 20-99% CPU) Expected results: kwin not very slow Additional info:
