Public bug reported: Yesterday I upgraded from Ubuntu 16.4 LTS to Ubuntu 18.4 LTS. Now, whenever my computer goes to the lock screen (either by manually locking, or timeout), I cannot return.
I see the date/time and notifications on the lock screen, I can drag up or press a key to see the password prompt. I can type my password and submit it either by pressing enter or clicking 'Next'. However, once I submit my password, authentication fails. Then if I try again, it doesn't accept any keystrokes, even if I click the password field. I CAN try again if I click Cancel. However, authentication always fails. I can "pause"/sleep my computer (using the menu in the upper right) and return, but I'm still in an endless login loop. Rebooting from this screen is not an option (except via power cycling the computer). If I choose to "log in as another user", then click myself, I get a mostly-empty screen: It has the status bar at the top and is the classic ubuntu purple, but otherwise blank. But at this point all I can do is reboot (shutdown/reboot is available from here) or choose another user. i.e. I still can't return to my current session. Please help! This is driving me nuts: I have to reboot every time I want to use my computer after a 5+ minute pause.
