    power: Avoid automatic logout in GDM/greeter
    
    In GDM sessions (greeter, initial-setup), it does not make sense to
    automatically logout. This can happen if the system wide default is
    changed to default to the "logout" action.
    
    Note that we already use the RUNNING_UNDER_GDM environment variable in
    the keyboard plugin currently. So doing this is likely sane, even if we
    probably want a more elegant strategy to detect whether we are in a
    "login" session.
