Found a work-around. I have GDM installed as well as lightdm. I typed: sudo dpkg-reconfigure gdm
to tell the system to use GDM instead of lightdm. Everything now works, but I still need permanent fix so I can stay 'standard' with lightdm. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/875542 Title: Can't login as administrator, only as Guest.
