This is the only "how to" that I have found that worked. I concur with Norman’s observation. This is the only “how to” that I have found that worked.

This is the best HowTo on the topic I've read, and I've read more than I'd have liked. And thank you too, Larry Lynn, you saved me a whole lot of hassle! Thank you.

I guess nvidia does not support it (?).

This was great. I've read maybe 5 articles and YOURS helped a lot. Now my DualHead is working. Hi :) Just wanted to thank you. This was great. I’ve read maybe 5 articles and YOURS helped a lot.

I had been screwing around, trying to get a dual monitor setup to work on my ubuntu system for the better part of 5 hours before I stumbled accress your tutorial. This was the clearest & most relavent tutorail for the configuration I wanted. After I found your tutorial, I was able to get the dual monitor setup working in under an hour. I did have a little bit of information to add. Your tutorial covers how to set up a system with multiple video cards controlling multiple monitors. I needed a setup where a single video card controlled 2 monitors. When I followed your instructions, I got the system to boot up & display, but not correctly. I had a duplicate image of the gdm gui on both monitors (2 duplicate desktops with 2 duplicate mouse pointers, both moving in sync & doing the same thing). I needed someting extra & figured it out by a process of trial & error. My specs: OS: Ubuntu 6.10 Video Card: ATI Technologies Inc Radeon RV100 QY [Radeon 7000/VE] Monitors: 2 x DELL 1707FP I actually got the key idea out of the man pages for xorg.conf. The subsection for screens under the devices section noted that the 'Screen' option was mandatory for a single PCI entity that would be used to drive more than one display. It also stated that multiple devices sections in the configuration section would be necessary. I ended up creating 2 "Device" sections, 1 for each screen. There is a lot of duplication between the 2 device sections. For instance , the 2 devices both use the same driver & BusID. The key difference is that one is set to screen 0 & one is set to screen 1. Here's a copy of the 2 device sections: Section "Device" Identifier "Screen0 of ATI Radeon 7000" Driver "radeon" BusID "PCI:1:0:0" Option "MergedFB" "false" Screen 0 EndSection Section "Device" Identifier "Screen1 of ATI Radeon 7000" Driver "radeon" BusID "PCI:1:0:0" Option "MergedFB" "false" Screen 1 EndSection I ended up with 2 device sections, 2 monitor sections & 2 screen sections. (Actually' there's more - I kept the defaults available in case my employer repurposes the video card for something else & I need to go back to the builtin). Hi,

I'm currently using KUbuntu 7.04 in a VMWare VM on Windows. I'm totally dependent on the flexibility of dual monitors, that's the ONLY reason I'm still using Windows as main OS. I see from this excellent HowTo that it's possible to use dual head, but can anyone confirm that it will do what I need? (easily switch between modes?) My current DELL Latitude D610 has an ATI mobile Radeon X300 card and I preferably use KDE. Thanks in advance. Olivier. Hi,

This worked wonders. Just wondering: I have a laptop setup with: - Monitor to the left (external) and - Laptop Monitor. In Xineramam Mode under ubuntu dapper + gdm all apps are started on th eleft screen which is bad when i'm on the road again... Any idea how i can tweak gdm into starting everything on Screen0 (which is the laptop screen?) (Card is a radeon rv350) Woud really appreciate any help as google hasn't turned up anything resourcefull yet. Thanks again! Fred Thanks! This worked wonders.

Since I didn't have one, I created it from an empty file and that caused X not to start properly. Nevermind, my problem was in following ubuntuguide.org to modify my .xinitrc.
