Thanks again!

I tried to come up with a python script to answer these requests, but
it’s bound to fail: gnome-session refuses to talk to anything but the
real gnome-shell (note the SHELL_NAME):

                proxy = dbus_g_proxy_new_for_name (shell->priv->bus_connection,
                                                   SHELL_NAME,
                                                   SHELL_END_SESSION_DIALOG_PATH,
                                                   SHELL_END_SESSION_DIALOG_INTERFACE);
(from gnome-session/gsm-shell.c).


With such a deep coupling of gnome-shell and gnome-session, I don’t
think its very viable to keep using gnome-session without gnome-shell.

Greetings,
Joachim
