The following started after upgrading from 19.04 to 19.10 using LiveUSB.
After enabling Auto Login for my user account, I still get a login screen, and entering my password just knocks me back to the login screen.
Going into terminal mode and editing /etc/gdm3/custom.conf to disable auto login allows me to login normally again:
<ctrl>-<alt>-F2 sudo nano /etc/gdm3/custom.conf
ensure AutomaticLoginEnable is set to 'False' and uncommented:
What could be causing this issue with Auto Login?
