Hmmm, the usual default behavior is that your laptop screen and the external device show the same image. You can force this behavior with a command like:

xrandr --output LVDS --auto --output VGA --auto --same-as LVDS

If you wanted to force a particular screen resolution for both screens, you could use something like:

xrandr --output LVDS 1024x768 --output VGA --auto --same-as LVDS
