Subject: [PATCH] e - randr2 - handle lid close/open as screen unplug/plug

when your laptop lid opens/closes even if we dont get a randr event
with a disconnect, the screen as logically been unplugged (you can't
see it anymore) so we should treat it as if the screen is not
connected. this fixes that.
