I have now done some investigating. I have found out that this problem arose after I disabled desktop effects. When a while ago switched from disabled to normal in desktop effects, the cpu usage instantly got normal again.
I got other problems with the graphics driver though. I tried to logout and then re-login but then my resolution was totally screwed. Normally I used 1280x1024 at work (docked) and 1680x1050 at home (un-docked). Now I got some 17??x???? resolution. And it was REALLY slow. You could see a window being rendered as if it was a serial console. I went into screens and graphic and noticed that I was using the vesa driver. Before in Feisty I used fglrx/ATI. I switched to fglrx and rebooted as instructed. Now the desktop didn't start at all but I got a window telling me I was in a safe mode. I tried switching from all possible resolutions and tried to go back to vesa but I was unable to start my desktop. I stopped gdm, copied my last known working Feisty xorg.conf to the current one and re-started gdm again. Now everything worked good! No high CPU usage either. I'm attaching my Feisty-xorg.conf and my Gutsy-generated xorg.conf. ** Attachment added: "Feisty and Gutsy xorg.conf's" http://launchpadlibrarian.net/9551133/xorg.conf.tar -- Xgl consumes lots of CPU on Gutsy https://bugs.launchpad.net/bugs/146285 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
