dual monitor setup on laptop with 915gm intel chip

[Valent Turkovic]

Has anybody an idea how to setup dual monitor setup with both laptop
screen and also external lcd screen (1280x1024) on my IBM R52?

I tried gnome-config-display but that doesn't work and it breaks my
xorg.conf so both my laptop and my screen boot with 800x600 resolution!

If I leave external LCD connected then laptop boots into 800x600
resolution which sucks.

Thank you in advance.
