Public bug reported: This Kubuntu machine had KDM installed before the upgrade from 12.04 to 14.04. After the upgrade there was no display manager left, i.e. kdm was no longer installed and it wasn't replaced by lightdm like it happened on another machine with a fresh Kubuntu 12.04 system.
The upgrade should either keep KDM or replace it by lightdm, but it should not leave the system in a state without display manager.
