I tried some different conditions with Screen Turn-off time-out and Lock settings, and I found the problem is not for the lock delay time, but for screen turn-off.
When you manually lock the screen and thescreen turn-off time-out passed, you will get the blank screen after unlocking; because the Unity lock screen has prevented the screen to go blank. So if you have “never” for screen turn-off, or unlock before the time-out reaches, you won’t see the bug. -- 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/1291365 Title: gnome screensaver locks again shortly after unlocking To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/1291365/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
