hello Guillaume! it looks quite nice!
Is it possible to add multi group support to gdm? my
idea is to asign a group of users to a different
/etc/X11/gdm/Sessions directory.
This will allow a single server to give different
Session options to different employees depending on
their job in a company off a different gdm group of
sessions to the teachers from the students at a
school.
What do you think about it? does it have a future?
comments?
btw, I am sure you will like a few gdm themes from
this site 8)

thanks!
