Unfortunately my problem is much wider. BTW my processor is in the "Broadwell" family with is the successor or "Haswell" family. To reproduce my problem: - Switch on computer. - log in and lock the screen (Alt+Ctrl+L) - Press switch to virtual text terminal (eg.: Alt+Ctrl+1) - use "top" to see what happening. compiz goes to 100% using one core. Checking CPU by CPU - hit "1" during running "top": One core works 30% user 70% system, other 99,9% idle. It IS very pity that nobody cares this issue, because quite decent systems with the latest Ubuntu is affected. -- 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/1322751 Title: Compiz running on Intel Haswell GPU has 100% CPU usage when computer is locked To manage notifications about this bug go to: https://bugs.launchpad.net/compiz/+bug/1322751/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : compiz@lists.launchpad.net Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
