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.
