Ubuntu – Unable to login after upgrading to 19.10 from 19.04

19.10

I just upgraded to Ubuntu 19.10. Upgrade was done via update manager GUI. I am using nvidia as a graphics driver.

After upgrade I get logged in but I get this screen:

How do I troubleshoot this?

I ran sudo dpkg --reconfigure -a. This resolved the first problem, but now I am at the login screen and unable to login.

I have looked at this question here:my .xauthority and .iceauthority permissions are correct although .xauthority is 0KB. /tmp permissions are also correct. I don't have lightdm installed.

I have also checked the Xorg.log and .xsession log. Renamed the extensions folder as well as the .xauthority file. no luck.

I had automatic login enabled. I just updated this file: /etc/gdm/custom.conf

and commented out these lines:

AutomaticLoginEnable=True
AutomaticLogin=username

After this I am able to login. Is this a bug?
