I'm glad I found this bug report. I was having exactly the same issue after I installed Ubuntu 12.10 (Had no such problem with 12.04). I had to reboot the machine every day or two as the UI was becoming very unresponsive and Xorg was using a lot of CPU.
I also confirm that installing the libcairo2 (and libpixman-1) from the 13.04 repository solves the problem. Thanks to the reporter for this workaround solution. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1073372 Title: Xorg produces high CPU usage, slow gnome-terminal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cairo/+bug/1073372/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
