A bit more about this - if I wait a while the keyboard does seem to come back but the problem is still there - my password is not accepted and then the keyboard does nothing for a while.

Status in gnome-shell package in Ubuntu: New Bug description: So yesterday I got the prompt to upgrade my 16LTS system to 18. Man am I sorry I went ahead with this; I am in a world of hurt. But the most frustrating issue out of many has to be this one. After a period of inactivity, the lock screen kicks in. When I then try to log in, using the correct password, I get a spinner for about 10 seconds, the "Authentication error". After a couple of seconds "Authentication error" goes away but now it seems no keys are registering at all in the password field. I say "it seems" because I see no "*"s as I type, but I do see occasional prompts of "Authentication error" coming back, but I haven't pinpointed the circumstances - certainly not triggered by hitting ENTER, sometimes backspace? Not sure if it has anything to do with the keys. After this all I can do is log in over ssh and reboot; I'm basically locked out on the console. This happens whether I have a USB keyboard connected or whether I am running Synergy and using a virtual keyboard. Mouse continues to work fine.
