>From the logs you've attached it's clear that your system is in a bit of a bad state - you've got the nvidia binary driver's libGL installed, but you don't seem to have the rest of the binary drivers installed.
I'd suggest going to jockey-kde and disabling the nvidia drivers, rebooting, then enabling the nvidia-drivers again. That will hopefully get you back into a sane state. If it doesn't please reopen this bug. ** Changed in: xserver-xorg-video-nouveau (Ubuntu) Status: Incomplete => Invalid -- X takes ~70% of CPU when Compiz is activated https://bugs.launchpad.net/bugs/545015 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
