This actually makes sense from a security perspective... It may not be a
great idea to allow the gdm user to be controlled from outside the GDM
screen, so a potential attacker can less easily gain access to your
login mechanism (and control/exploit it). I'm sure that given time,
though, there will come some easier way to control some of the basic
login screen features (such as themes).
