Good to hear it's solved for you! The strange thing is that I just replaced that broken CRT with the new LCD monitor. Just disconnected the old monitor and connected the new one. Boom, high CPU usage :-(. I didn't install any new software, etc.
I never had this before in 2,5 years and as I said I still have this problem under 14.04, even though the CPU usage there seems to be a bit lower than under 13.10 (I assume due to optimizations in the whole graphics stack). The funny thing is that I have high CPU usage even when the external monitor is in stand-by/powered off, but when I physically disconnect it (by either removing the VGA cable from the VGA port or unplugging the KVM switch's USB cable which also provides the power for that thing), everything is okay. Makes me wonder what's going on there. -- 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
