Essentially the way it works is that there's a total amount of virtual 
screen space for xrandr or other tools to use.  I have the Intel chip 
and it has a limit of 2048x2048.  What I choose to do is clone my LCD at 
1024x768 on to the video port at 1024x768.  Works great and I can use 
the standard Ubuntu resolution settings to do this.
