Dual Monitor on Ubuntu/Dapper

I've noticed a number of people asking about dual head support in dapper on #ubuntu, so here is my setup:

This hp/compaq nc6000 laptop/notebook that has an ATI card:


$ sudo lspci|grep VGA
0000:01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]


I have two head monitors working with both the 'ati' and the closed source 'fglrx' drivers.

Here are the configuration files:

xorg.conf-fglrx.20060621 -- works when booting without the second monitor

xorg.conf-ati.20060621 -- when booting with out the second monitor attached, it still thinks it is there. Some windows may pop up on the unreachable monitor.

Before you start hacking around with your xorg.conf, save a copy somewhere safe.
