Given that running X as root has long (pretty much as long as X has
existed) been considered a bad idea, most display managers (kdm/gdm/etc)
don't permit root to login to X by default. You can change the config
to permit it, although I wouldn't recommend it.
So some options you have are:
Login as a normal user and use 'su -' to run as root temporarily, or
sudo, or gtksu or similar to allow root to run a single application in
Change the config of the display manager to permit root.
I never login to X as root and use the other options instead.
But either way, it is working as it should.
As someone else mentioned, left control + left alt + F1 (through F6)
should give you text consoles where root can login.
