How to make work dual monitors with Debian etch on an IBM x60s ThinkPad?

Hi,

I am using Debian etch on an IBM x60s ThinkPad
and would like to use the laptop monitor in parallel with an external one.

But whatever I try - if an external monitor is connected, the laptop
monitor remains black...

If there is anybody who could have a look on my attempts to make this work
using the /etc/X11/xorg.conf file, I would be most grateful :)

Is there anything else than changing the /etc/X11/xorg.conf configuration
I could / should try?

Thanks, Dietrich
