    ScreenShield: hide the lightboxes when resuming from suspend
    
    We show a lightbox when we suspend, to animate the fading to black
    caused by turning off the monitors, but we need to hide it when
    coming back, otherwise the user is just staring at a black screen
    it until he moves the mouse or presses a key.
