Hi everyone
i've followed a lot of tutorials and how-tos without success, here's my problem:

I've a HP Compaq NX7010 with ATI Radeon Mobility 9200 video card, and an external NEC LCD1701 monitor; i'd like to configure the extension (not mirror) of the desktop onto this monitor, i've played with my xorg.conf file but if i launch startx when the NEC monitor is connected, then the display of the notebook goes off and the NEC become the only active monitor; if i connect the NEC monitor after launched startx, then i obtain a clone of the desktop in the LCD notebook display. I'm using XFCE4

Here follows my xorg.conf

Code:
