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.


    1. Thanks for posting. I have a friend with a dual head setup who asked me about this the other day. I'm going to forward this to him.

    2. [...] This is a follow on to last week’s post about Dual Monitor on Ubuntu/Dapper [...]

    3. Good day Nozell

      You're post on Dual Monitor support was the first that came up when I searched. I've had Ubuntu running for about 3 hours now, and for my first time Linux experience it has been quite good...
      Until now.
      I see that you have configuration scripts avaliable for running your ATi cards dual monitor support, I happen to have a Radeon RV100 QY [Radeon 7000/VE], and I was wondering if you (or anyone else reading this) could give a new Linux user a pointer in the right direction to find out how to use such configuration scripts.


    4. I get a 404 error when trying to view your xorg.conf files! halp!


    5. yk,

      Thanks, I was cleaning up the website and removed too much. The files have been restored.
