Multiple monitors Problem ?

[Face]

Hello all,
I am trying to setup xorg.conf for 2 monitors
     1. Labtop monitors (LVDS1)
     2. External monitors (HDMI1)

so i need the  External monitors  to be the man screen and Labtop
monitors to be the External for it. However, all i got so far is a
duble of one screen display on both screens. so if i open something it
will be display on both screen.
