Are you running the xfwm built-in compositing? I've found that, on a Xubuntu machine using xfwm and compositing, the desktop would be shown together with the "unlock dialog".
Expected behaviour: Lock screen -> move mouse -> black screen surrounding the "unlock dialog" Seen behaviour: Lock screen -> move mouse -> the desktop surrounds the "unlock dialog" Workaround 1: Disable compositing from the "Preferences" -> "Window manager settings" -> "Compositing" tab Workaround 2: On the previous tab, make sure the second option (too long to remember) is unchecked. -- xubuntu Gutsy: Screensaver shows user's screen at password prompt https://bugs.launchpad.net/bugs/160636 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
