When compiz finds a fullscreen window, it calls "XCompositeUnredirectWindow()" on it. This has side effects that confuse gnome-screensavers lock dialog. It assume it has the keyboard grab already, when in fact it does not have it:
[gs_grab_move_keyboard] gs-grab-x11.c:324 (00:41:01): Window 2200024 is already grabbed, skipping [gs_grab_move_mouse] gs-grab-x11.c:264 (00:41:01): Window 2200024 is already grabbed, skipping the proposed fix changes this so that it will always (re)grab the keyboard. This change needs to be tested as widely as possible before we publish it. -- Keyboard shortcut works even when the screen is locked https://bugs.launchpad.net/bugs/145123 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
