I've seen the lockup from kwin using 100% cpu on two different Kubuntu 14.04 machines, without needing to switch users. These machines were ungrades from previous versions, 12.04 and 13.10.
I think its fixed by resetting the kwin configure file by: run "System Settings" select "Configure desktop effects" then clicking "Defaults" (at the bottom) and then "Apply" (at the bottom right). If you can get to term with Alt-Ctrl-F1, you can use "DISPLAY=:0 kwin --replace" to fix a broken kwin using 100% cpu. This also works if you can "ssh" in. -- You received this bug notification because you are a member of Kubuntu Bugs, which is subscribed to kde-workspace in Ubuntu. https://bugs.launchpad.net/bugs/1272438 Title: kwin 100% of cpu, second session To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/1272438/+subscriptions -- kubuntu-bugs mailing list kubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/kubuntu-bugs
