I finally got my 24" monitor though not the same brand, it is an LG.

I am not able to configure this monitor with my laptop under linux as I
can with Windows. My laptop runs at 1280x800 and my new monitor at
1920x1200. I am able to view one at a time in their native resolutions
but trying to bring up X with two different resolutions fails. Is this a
limitation of X or the intel driver?

Second I would like to use my new monitor as an extension of my laptop
but all I can see is the same desktop on both screens. I have tried the
Xinerama option under ServerLayout but it freezes my who laptop.
