This bug also affects me on 12.04. I have a Lenovo Tinkpad x200s with Intel graphics. I tried to track what is causing the high load and can't be sure if it's this, but my best result so far is:
+ 13.06% compiz libdricore.so [.] _mesa_Scissor I'm also using a docking station with multi monitor setup, if that matters. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/771238 Title: Compiz 100% CPU over all cores after resuming from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/771238/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
