I have the same issue as well with ATI Mobile HD 5000 Series on HP Probook 4321s laptop.
- Xorg and compiz occupy enormous CPU resources while ubuntu is on screen-auto-suspend or battery-mode. - Reloading Compiz or Unity makes the system responsive again. - In the case on battery-mode, plugging AC power is not a immediately solution. My laptop needs 2~5 minutes to be normalized after plugging AC power. - But I can't find critical error message in /var/log/xorg.0.log - I can reproduce this every time. If you need additional logs etc., mail me [email protected] HP Probook 4321s CPU : Intel Core i3 M380 @2.53Ghz VGA : ATI Mobility Radeon HD 5000 Series (proprietary AMD/ATI FGLRX driver) OS : Ubuntu 12.04 Precise amdx64 -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/1015346 Title: high compiz cpu occupation after the screen auto suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1015346/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
