It sounds like you have bug 2104183 which could affect both the login
screen and user session. We could wait and see if the problem goes away
after that bug fix is released, or you could try collecting crash
reports to confirm it sooner;
1. Run these commands:
journalctl -b0 > journal.txt
journalctl -b-1 > prevjournal.txt
and attach the resulting text files here.
2. Look in /var/crash for crash files and if found run:
ubuntu-bug YOURFILE.crash
Then tell us the ID of the newly-created bug.
3. If step 2 failed then look at https://errors.ubuntu.com/user/ID where
ID is the content of file /var/lib/whoopsie/whoopsie-id on the machine.
Do you find any links to recent problems on that page? If so then please
send the links to us.
Please take care to avoid attaching .crash files to bugs as we are
unable to process them as file attachments. It would also be a security
risk for yourself.
