Laptop VGA cards are only two types: independently driven, or
mirrored. The former is what allows the internal and external to
display different things simultaneously. The latter is a 1:1 mirror
image on one and other. All laptops I've seen when the external VGA
is enabled are mirrored. Via VGA driver functions, you can make them
independent.
My guess for what you need is xrandr, to which I'm not very well
versed. It seems to be "the answer" when it comes to video output
layout, size, orientation... swiss army knife.
That did the trick for anyone else with the same setup put this in any
of your personal rc's like .xsession:
xrander --output LCVDS --off --output VGA --auto
I'm welcome to corrections and learning myself, but I would shoot for
VGA driver and/or xrandr tweaking first.

and I have an extrtnal 21" widescreen (vga) that when I hook it up the
default x11.config has it at 1024x768 on *BOTH* monitors.... How do
I make it so X only considers the external (if attached) monitor?
