I will attach 3 files with the output of xrandr --verbose. However, this is with Precise w/o edgers ppa. I'll first update to edgers ppa, do it again, then later try Raring.

First file is xrandr --verbose when booting w/o VGA external connected (and still disconnected). So this is "baseline".

Second file is xrandr --verbose after plugging in VGA external (but having booted w/o it). This is the scenario where the screen is "blank" getting "no signal" even though "Displays" indicates it is connected and "on".

Third file is xrandr --verbose after booting with VGA external connected. In this case (and only in this case), the external works properly.
