Twinview on Dell Precision M40 /Nvidia Quadro 2 GO

Help, I am trying and trying and trying to get twinview to work on my laptop running distribution Mandrake10 Community I want my 18' flat panel to be the secondary monitor (1280*1024), and the laptops display (1600*1200) to be the main monitor right of the flat panel. How am I supposed to do that?

When disabling twinview, the laptop screen works at 1600*1200 and the flatpanel at 1280*1024.

Gratefully, Gyrrus
