For your crt/lcd monitor -> maybe this issue depends on the resolution of the external screen.
Does appear that issue if you have connected your screen at boot-time, then disconnected when the lightdm login screen is showing and you logged in (without connected external screen)? Today I had the problem again. Booted and did login (external monitor connected over vga but not used for output)-> high compiz cpu usage logged out and in again -> high cpu disonnected monitor, logged out, logged in -> normal compiz cpu usage again logged out/in -> normal compiz cpu usage connected monitor again, logged out/in -> high compiz cpu usage again (still the external monitor is not used for output) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1222602 Title: [regression] [gen3] Mesa 9.2 makes Unity unusable on Atom class hardware and 943/945 graphics controllers To manage notifications about this bug go to: https://bugs.launchpad.net/mesa/+bug/1222602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
