Attempted to reproduce it on Precise using an Intel gfx laptop docked with external monitor. Initially on open a dozen windows the CPU got slightly higher but still hardly got near 0.10, then dropped back down to 0.01. So, this is likely nvidia-specific, and I'll bet this is the same as bug #877438. I'll set as a dupe. ** This bug has been marked a duplicate of bug 877438 Unity compiz plugin makes display slow on multi-screen -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/737454 Title: xorg high cpu usage with compiz while using top command; goes away when compiz is killed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/737454/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
