Are you perhaps referring to the laptop's LCD display and the VGA out at the back as "dual display?" If so, then you are wasting your time trying to configure multi head display. Typically on a laptop, you can toggle the video HW to display on (a) LCD only, (b) Both (LCD+VGA), (c) VGA only.
I too remember quite distinctly reading an article which showed how to setup two individual displays on a laptop even with the chip driver not supporting dual heads. It used xinerama. Right now I cannot find the link. Google around I am pretty sure theres a hack for this.
I stand corrected w.r.t my post re dual head display on laptops. Some video chips sets in "newer" laptops do support dual head thru LCD and the VGA port *but* it is chip specific and not generic (from Google search for "dual+head+display+laptop+linux."
The OP needs to do his home work (research his video hardware) and figure if the X server for his chip set supports dual head. If so, then the following can help him http://www.granneman.com/techinfo/linux/installation/dualheadhowto.htm
