gdm setup and faces

[Adam Pribyl <pribyl lowlevel cz>]

In F8 the GDM setup was available to setup which users should show up in 
GDM and there was possible to assign faces instead those "Unknown" 
persons. How to do this in F9s' GDM?

I put .faces icons to users home, but this does not show in GDM, and I did 
not found a way how to setup any GDM parameters (from GUI).

Thanks for any hint
