    Monitor: don't shortcut set_power_save if the value is the same as the old one
    
    We don't get notifications from X11 when the mode is reset, so
    our cached value can get stale. To work around that, always forward
    requests to the backend (and let it deal with ignoring the change
    if wanted)
