I just upgraded to 18.04 from 16.04. The upgrade went through with no error messages, but I hit the login loop right after the upgrade: at the login page, after typing the correct password, the screen goes black for 1-2 seconds and then goes back to the original login page. I have tried various suggestions found online (including this forum). An incomplete list of items I tried are:
- Removed and reinstalled the latest Nvidia driver
- Removed
~/.localfolder - checked all customized entries in
~/.profile - removed the
~/.Xauthorityfile - checked that my account has the ownership of the
~/.ICEauthority - switched between GDM3 and LightDM (the symptom is the same between different display managers)
There are probably a few other things I tried that I cannot recall anymore. Finally, I found that through LightDM I have three desktop environments to choose from:
- Ubuntu
- Ubuntu on wayland
- Unity (default)
By default, the system directs me to the first option "Ubuntu" (which I assume is the new Gnome environment?). If I switch to unity, the desktop does load with no issues. Wayland has the same login loop problem.
Up to this point, I am running out of options. I am now sticking with unity and not sure if this is a good long-term solution. Any thoughts on why GNOME does not launch?
The machine is an "Asus N56JR" laptop.
