I'm lowering the severity of this bug since gnome-shell 3.5.91-0ubuntu1 now won't refuse to unlock if LightDM is used.
It will however make your screen appear locked but you won't need a password to unlock it, so that's still a bug but not as critical. Discussion is still continuing on the GNOME bug. ** Changed in: gnome-shell (Ubuntu) Importance: High => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1042907 Title: LightDM doesn't handle Lock Screen or Switch Session for GNOME Shell 3.5 To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1042907/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
