I experience this in precise, but only when running a unity session, and also not really reliably on two (sandy-bridge) systems.
One system is a desktop PC running a radeon 6670 graphics card. There, I experienced this each time when resuming after suspending the machine reliably. Switching from unity to gnome3 seems to help. The other system is a laptop that was recently upgraded to precise. I have added a session item that locks the screen when logging in (because the system is configured to auto-login). Here, the described symptom happens already at login time. -- 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/712103 Title: unlocking dialog doesn't show To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/712103/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
