I appear to have the same problem when playing Battle for Wesnoth in full screen mode. Its fairly clear that the Battle for Wesnoth window has grabbed the mouse because some clicks produce game sounds.
The mouse pointer cannot be moved to the top of the screen, so I cannot interact with switch user or anything else in that bar. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1305586 Title: Lock screen is unusable when some windows have a keyboard/mouse grab To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1305586/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
