Issue 20: xrandr to make the resolution lesser does not update the geometry http://code.google.com/p/xmonad/issues/detail?id=20 Comment #3 by SpencerJanssen: In the non-Xinerama path, getScreenInfo uses Xlib's DisplayWidth/Height. Xlib (dubiously) caches these values. Instead of trusting Xlib, we check the dimensions of the root window.
