Hi, I'm using a standard Ubuntu 18.04 (GDM and Gnome under XOrg) and a Dell workstation. I was using an AMD Radeon Pro card but moved over to an NVidia GTX 2070. I managed to disable the Noveau drivers and install the Nvidia proprietary drivers, and it seems to work fine (Nvidia drivers are running). But my main admin account is not lot logging in, I get a boot loop when I enter my user password. Another account (non-admin), logs in just fine, so there is something in my settings. Looking at /var/log/syslog it seems that MIT-MAGIC-COOKIE-1 is causing the problem. I did have an .ICEAuthority but deleted it based on advice on how to fix boot loop: it didn't work. I don't have an .XAuthority file.
