This bug is present in 16.04 with current updates, however it only started around a week ago so it was probably introduced in a recent update.
It is not a duplicate of 1311316 as the password box is still there, it just doesn't accept keyboard input. A work-around is to start and logout from a guest session, then when returning to the login screen the password field works normally. ** This bug is no longer a duplicate of bug 1311316 After locking screen there is no input field to type password for unlock -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1311403 Title: Can't type password after resume.
