Having this issue as well on 15.10. Partial fix: After killing gnome-screensaver from a TTY, I've found that running:
gnome-screensaver-command -a activates the screen saver, but once unlocked, eliminates the screen- blanking problem that Tony Maro described. Will also try "gnome-screensaver-command -d" instead of killing gnome- screensaver next time it happens to see if it works better. -- 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/744619 Title: Screen doesn't unlock; stuck on "Checking" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-screensaver/+bug/744619/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
