Public bug reported:
The user is unable to login from the login screen. The password is
accepted but the password prompt is displayed again.

Note that the login screen appears even though I had specified auto login.
Perhaps this one line is important:
Oct 14 14:41:24 carbon gdm3: GdmSession: Considering session (null) for
username (null)
I am using an NVIDIA RTX 2080Ti with the bundled drivers.
When used via ssh, the following brings the system to a working desktop:
sudo service gdm restart
However, when this was used from a terminal from ctrl-alt-F3 the system
locked completely and was unresponsive over ssh.
/var/log/syslog is below:
