That's basically what it does, but it also sends out a signal that it's going to shutdown to all the applications to allow them to inhibit the shutdown for various reasons. http://www.gnome.org/~mccann/gnome-session/docs/gnome-session.html#id2735819 This could be that a document isn't saved or just because you feel like it. I'm not sure if any apps have implemented all of the new API. There's been some talk about putting it into GTK+, but I don't believe that there is anything today. But, maybe that is the fix. Maybe we should extend gnome-session to have enough options that we just call it directly? That way it doesn't give us the big ugly dialogs, but it can handle the PK/CK stuff. There is currently only commands to bring up dialogs: http://www.gnome.org/~mccann/gnome-session/docs/gnome-session.html#org.gnome.SessionManager.Shutdown --Ted
