I have a dual-head CRT-display setup that worked with Ubuntu Feisty Fawn. It consists of an ATI Radeon 9600 (RV350), a Compaq P1100, and a Compaq V1100 (both CRT monitors). Attached is my xorg.conf file. These are the versions included with Gutsy Gibbon: xrandr-1.2 xorg-7.2 xserver-xorg-7.2 xserver-xorg-core-1.3 xserver-xorg-video-ati-6.7.195 When my computer boots, both the kdm and KDE desktop only activates the VGA-0 output (Compaq P1100 CRT monitor-Left). When I execute these commands, the desktop grows correctly but the DVI-0 output does not turn on the Compaq V1100 CRT monitor-Right: xrandr --addmode DVI-0 1600x1200 xrandr --output DVI-0 --mode 1600x1200 --right-of VGA-0 Is the problem: 1. Do I need xorg-7.3 and xserver-xorg-core-1.4? 2. Is the monitor too old to be detected (~1999)? 3. The DVI->VGA adapter I use? 4. Do I need to add a Device Section in xorg.conf for the PCI:1:0:1 secondary adapter? 5. Is there a bug in the radeon driver?

Now, the V1100 is the only monitor turned on and the P1100 is off. I am not sure why the V1100 is at the 1280x800 resolution, it can easily handle 1600x1200.

Ok, after the 3 xrandr commands you specified, I get good output on my V1100 monitor on DVI-0. Thanks for that! The output is below...the V100 monitor's menu says "New Mode @ 85 Hz" but I doubt that is cause for alarm. 1. Is this an elegant or "correct" solution to the problem? Should I bother investigating more? 2. How can I make xorg.conf do this every time at boot-up? $ xrandr -q Screen 0: minimum 320 x 200, current 3200 x 1200, maximum 3200 x 1200 VGA-0 connected 1600x1200+0+0 (normal left inverted right) 380mm x 290mm 1600x1200 85.0*+ 1280x1024 84.8 75.0 1152x864 75.0 74.8 1024x768 84.9 75.1 70.1 60.0 43.5 832x624 74.6 800x600 84.9 72.2 75.0 60.3 56.2 640x480 84.6 75.0 72.8 66.7 60.0 720x400 87.8 70.1 640x350 85.1 DVI-0 disconnected 1600x1200+1600+0 (normal left inverted right) 0mm x 0mm 1600x1200 85.0* S-video disconnected (normal left inverted right)

Same xorg.conf file as before. On the primary dac we are able to use load detection to see if a monitor is attached. In this case, we find one, but since it has no edid, the server just added the default sync ranges and modes. > > > $ xrandr -q > Screen 0: minimum 320 x 200, current 1280 x 800, maximum 3200 x 1200 > VGA-0 connected 1280x800+0+0 (normal left inverted right) 0mm x 0mm > 1280x800 60.0* > 1280x768 60.0 > 1024x768 60.0 > 800x600 60.3 > 640x480 59.9 > DVI-0 disconnected (normal left inverted right) > S-video disconnected (normal left inverted right) > This doesn't seem right. The log clearly shows an edid on the monitor on the dvi port initially. later in the log it disappears. are you sure you didn't disconnect the monitor on the dvi port at some point?
Created attachment 12898 [details] Xorg.log when V1100 monitor is on VGA-0 and P1100 monitor is on DVI-0; after full reboot. Before, I had swapped the cables and then restarted the X Server.

You'll have to specify add a monitor section for VGA-0 however since that monitor does not provide an edid. With this set up you shold be able to set up your desktop as you want it with minimal configuration. Either: xrandr --addmode VGA-0 1600x1200 xrandr --output VGA-0 --mode 1600x1200 xrandr --output DVI-0 --mode 1600x1200 --right-of VGA-0 at runtime or add the the configuration you want to your xorg.conf. Take a look at this page for more info: http://www.intellinuxgraphics.com/dualhead.html It's an intel page, but that same information is applicable to any randr 1.2 capable driver. Basically you'll want to add monitor sections for each monitor and then associate the monitor sections with an output, then specify the orientation in one of the monitor sections.
