I have an HP nc5320 laptop I am trying to setup to span the display across
the laptop screen(Max Res 1024x768)and an external LCD display(Max Res
1280x1024).

I would like to use the max resolution on both and this works when I boot
the laptop to Windows XP.  If I must go with a max of 1024x768 on both
that would also work but is not ideal.

I don't want to use Windows XP and I need my screen real estate so I want
to get this working with OpenSuSE 10.3.  Currently I can only get it to
close the 1024x768  display to the external monitor.

I followed http://www.intellinuxgraphics.org/dualhead.html and tried both
methods and neither worked.

xrandr -q outputs the below:
