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 Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/744619 Title: Screen doesn't unlock; stuck on "Checking" Status in gnome-screensaver package in Ubuntu: Confirmed Bug description: Binary package hint: gnome-screensaver When I lock the screen either by using the screensaver, locking manually, or returning from a hibernate, when the authentication dialog comes up, it doesn't unlock the screen when I enter my password. Instead, it just hangs on "Checking..." forever until I manually kill gnome-screensaver. This is on a Lenovo Ideapad, with Ubuntu 10.10 i386.
