Question regarding the new login theme and using other gdm themes

[Dennis Beekman]

Sadly i have to report that even in the Beta version the loginscreen
background or colortscheme can not be altered.
I tried using gdmsetup but this doesn't allow anything to be changed...
other then automatic/manual login features.

In the old GDM you could switch the themes off and just have a standard
login windows with a logo and a background....
Is this feature not going to be part of the new setup ?
