I also started having this issue after upgrading from 15.10 to 16.04. Sometimes I can see the flicker of the gnome-screensaver-dialog showing up, but most of the time I just see my previous screen, without anywhere to type in the password, and everything locked (nothing is interactive).
Typing the password on the blind actually unlocks it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311316 Title: After locking screen there is no input field to type password for unlock To manage notifications about this bug go to: https://bugs.launchpad.net/unity/+bug/1311316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
