LightDM - Sep 2014 - user-session not working

Hello all,

Just wondering why our default user-session is not working. Two window managers
installed (gnome-classic and mate), mate is our best prefered, but when a brand
new
user is trying his first login, gnome-classic is started.

/etc/lightdm/
#
# Seat defaults
#
# type = Seat type (xlocal, xremote)

user-session = mate

and in the log file :

+106.80s] DEBUG: Session pid=964: Authenticate result for user xxxx: Success
[+106.80s] DEBUG: Session pid=964: User xxxx authorized

Any help would be appreciated.

Hum, after reading greeter.c, I should receive

"Greeter requests default session"
rather than
"Greeter requests session gnome-classic"

/* Use session type chosen in remote session */
    if (greeter->priv->remote_session)
    {
        session_type = SESSION_TYPE_REMOTE;
        session = greeter->priv->remote_session;
    }

So, session seems to be "gnome-classic" and my question is now
why greeter->priv->remote_session returns "gnome-classic" in the
case
of a brand new user (with an empty homedir).

Any help would be appreciated.

cheers !
