And you are right you can't login as root in KDE,You can use a terminal emulator to run sudo or to su to the root account after you've logged in. The wiki will have the details. The default terminal emulator in KDE is Konsole but you can use something else if you prefer.but I think you can change /opt/kde/share/config/kdm/kdmrc AllowRootlogins=false to true (HowTos)
