I just upgraded from 16.04 to 18.04, and now I can’t get past my login screen. TTY terminals are available.
Things I have tried:
- Reinstalling and reconfiguring lightdm
- Changing permissions and ownership of .ICEauthority and .Xauthority files
- Nothing interesting in lightdm logs or in .xsession-errors
- Deleting all Gnome extensions
- Deleting .local directory
- Reinstall GDM, gnome
