What specific problems are you finding?

I do not believe that the user has any ability to change any session
configuration while the GDM login screen is running.  Are there any
specific configuration options that you are finding are causing problems
when using GDM in a multi-user environment?

GDM has used gnome-session, gnome-settings-daemon, and metacity while
the login screen is running since GNOME 2.21.  GDM 2.21 was a complete
rewrite, and uses a completely new codebase.

In GDM 2.20 and earlier, GDM used its own simple window manager and did
not use a real session manager or settings daemon.
