I had a similar problem which made me at first unable to enter the Ubuntu session. It was caused by my right shift key had not correctly been recognised as released. Maybe because of at the moment heavy loaded CPU, missed interrupt.
Steps I used: 1) Leave message 2) Enter password (or all keys that is included) 3) Press all kinds of keys (i.e. shift, ctrl) until it is correctly shown. 4) Press Cancel to don't leave the message. It worked for me! -- 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/774273 Title: unlock screen no longer works -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
