Actually one more comment - I was digging into my auth.log and it may be video related. The logs when it failed to unlock and when it succeeds are identical. I then noticed that one of my three monitors shows garbage at the bottom when I tap the top left corner to bring up the app chooser view in Gnome 3.
It makes me wonder if the screensaver isn't authenticating you properly, then just failing to go away... Logs on a successful unlock and on a failure look identical: May 17 10:31:46 river gnome-screensaver-dialog: pam_unix(gnome-screensaver:auth): authentication failure; logname= uid=1000 euid=1000 tty=:0.0 ruser= rhost= user=tony May 17 10:31:47 river gnome-screensaver-dialog: pam_sss(gnome-screensaver:auth): authentication success; logname= uid=1000 euid=1000 tty=:0.0 ruser= rhost= user=tony May 17 10:31:47 river gnome-screensaver-dialog: gkr-pam: unlocked login keyring -- 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
