Hello,

The monitor i used is an HP 1720 LCD, when plugged to my laptop, it display the same think as on the laptop's monitor, but with big vibration and trying to ajust frequency every two seconds.

I want to display all my desktop on two screen, I can do it with WindozXP,

PCI:1:0:0 is one device not 2.

Then in the Both screens your using the same device:
[code]Section "Screen"
        Identifier      "Screen0"
        Device          "nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300]"

And ...

Section "Screen"
        Identifier      "Screen1"
        Device          "nVidia Corporation G72M [Quadro NVS 110M/GeForce Go 7300]"
