[Bug 1793956] Re: After upgrade from 16.04 to 18.04 : GDM login failure

[Sebastien Bacher]

Could you add the journalctl log from the machine after a failing login?

** Package changed: ubuntu-release-upgrader (Ubuntu) => gdm (Ubuntu)

** Changed in: gdm (Ubuntu)
   Importance: Undecided => High

** Changed in: gdm (Ubuntu)
       Status: New => Incomplete

** Package changed: gdm (Ubuntu) => gdm3 (Ubuntu)

  After upgrade from 16.04 to 18.04 : GDM login failure

Status in gdm3 package in Ubuntu:
  Incomplete

Bug description:
  Hi ,

  One of our client upgraded his system ( full intel from clevo ) from
  16.04 to 18.04.

  
  After that he cannot login from GDM (tried ubuntu/Unity/gnome-flashback) 

  However he can login from VT1 .

  No "password incorrect" error is returned just looping back to gdm
  welcome screen.
