Bug description:
 - open grandr
 - switch resolution to 800x600 (from 1024x768 in my test case)
 - press "apply"
 - things will work
 - switch back to 1024x768
 - press apply
 - you'll see 2 black rectangles, one at the right side and one at the bottom
   side of the window

According to Gustavo Boiko, this happens because of problems in the
timing/order the events are sent, so we need a few calls to XSync and
X{G,Ung}rabServer.
But we have 3+ open connections to the X server! That's a problem when we use
XGrabServer. One is from gtk, one is from XOpenDisplay at grandr.c and the
others are from XOpenDisplay at the screen_apply function (and these leak!).
This patch makes everyone use the gdk display.
