You must indicate in the xorg.conf that you want to use a virtual screen 
bigger than your laptop's one. Here is what I have for two 1024x768 screens 
side by side.

Section "Screen"
    Identifier "screen1"
    Device "device1"
    Monitor "monitor1"
    SubSection "Display"
            Virtual 2048 768

You will need 1280+1024 (I suppose a typo in the 1200) horizontaly so :

Virtual 2304 1024

Than as said you can get it OK with something like (my own script, adapt to 
your config) :

        xrandr --addmode VGA-1  1024x768
        xrandr --output VGA-1 -s 1024x768
        xrandr --output VGA-1 --auto
        xrandr --output VGA-1 --right-of LVDS

You may have some problems with 3D (DRI) as 2304 > 2048...
