Bug Description

After upgrading to ubuntu 18.04, my nvidia driver was updated to version nvidia-390 and now I'm unable to login from lightdm with regular users. I tried other display managers, but I have the same issue.

Finally, I found out that if I login as root, the session is properly started

What exactly do you mean by "unable to login"? When I try to login with GDM the monitor turns simply black. Another observation is that I cannot switch to tty neither from that black screen nor from GDM before.

The problem is gone for me after upgrading to 18.10.
