    loginDialog: disconnect greeter when switching away VTs
    
    At the moment the greeter stays connected to GDM even after the
    user logs in.  That stale connection can lead to bookkeeping
    confusion later on.
    
    This commit makes sure we disconnect the greeter connection any
    time the user logs in or otherwise switches VTs.
    
    This commit also make sure we do a full reset when VT switching
    back later, so the greeter connection can get re-setup.
