Default Attach 2nd display to notebook and clone image

Hello,

I have a notebook that does 1600x900 and has a G210M chip. I have attached a 2nd TFT to the VGA connector and it is a Samsung that can do 1680x1050.

What i would like to have is two *identical* desktops, one at the laptop at 1600x900 and the other on the 2nd external monitor at 1680x1050.

So, when I connect to the external monitor i always get the same desktop. I have played with the nVidia Xorg tool, but to no avail. I have no clue what it means to place the 2nd screen "above", "below", "right" or "left". I want to exactly clone my desktop...

What would be the syntax for xorg.conf? Or how could i do this with the Xorg nVidia tool ?

Ok, i was able to enable TwinView, but it is odd, I can see my desktop on the 2nd monitor, but when i start an application the app is been seen on the notebook... this is not what I want, I want an exact clone...

SOLVED I was now able to create a xorg.conf that does the job, see below. I created it with the nVidia tool. I can now plug in my external monitor, restart X and then have my desktop on the big monitor. Can unplug it again, restart X and then have my notebook desktop again.
