Every month or so it occurs (a system, that is never shut down) What I do is that I ssh in from another box and kill the high-load process. If I can't find out which one it is (happened once), I restart X.
I think it is related to that I have an nVidia Quadro NVS 450 with three displays and Ubuntu 11.04 effectively stopped supporting more than one display. X or GPU gets confused and draws in the wrong rectangle. A window might update on display 1 but is all black on display 2. This was all good on 10.10 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/738458 Title: Gnome won't show screen saver unlock, clock-applet high cpu To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/738458/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
