Just to be clear, I associate restarting gnome with logging out then logging in again. Not with unplugging the monitor and reconnecting.
Concerning the present bug report, I'm becoming confident that the flickering black bar appears at the top of the secondary monitor after the following steps: 1 - Lock the screen, either manually or waiting for the timeout. 2 - Wait for screen to sleep. 3 - Unlock the screen Logging out/in eliminates the black bar, and restores normal behaviour until the next time the screen locks and sleeps. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2074559 Title: [nouveau] Top margin of secondary monitor covered with black flickering rectangle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2074559/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
