After upgrading from 16.04 to 18.04 (keeping home directories, formating root) I cannot log in. After the password is accepted, gdm silently goes back to the login screen.
I can change run levels and log in there. In /var/log/syslog
I find:
Fatal server error:
Cannot open log file "/home/myuser/.local/share/xort/Xorg.pid-1768.log"
...
Unable to run X server
How is that even possible?
Checking the home folder, I note that there's a readme and some Access-Your-Private-Data.desktop
; I can access neither. What happened here?
