fprintd is started, lots of pam_sm_authenticate messages. I *think* this
corresponds to the issue occuring after boot (it's not the scene I recorded in
the video).

I switched to console 2 and logged in succesfully. Tried some commands on the
console. I don't think they made a difference.

Now the graphical login worked. Fingerprint authentication did not (it's
usually about 50:50 on this system), but I was able to log in using my
password.
