I am attempting to get a dual head setup to work with my ATI x1650 pro and the radeonhd driver. My xorg.conf (below) is very simple (I have been working from http://wiki.x.org/wiki/radeonhd)
and while both monitors do come up they are clones of each other. I want the setup to be static so I have been attempting to get all of the config into the xorg.conf but attempting to run things like:
xrandr --output DVI-I_1 --right-of DVI-I_2
does not seem to do anything either.

Does anyone have a good resource for me to read through or some helpful hints on how to disable the cloning?

Thanks.

Identifier "monitor_1"
EndSection

Which version of the Xserver are you using?

I am seeing similar problems.

Build ID: xorg-x11-server 1.3.0.0-42.fc8
...
(WW) RADEONHD(0): Option "LeftOf" is not used
...
(WW) RADEONHD(0): Option "RightOf" is not used

I am attempting to set this up on a Ubuntu box. The xserver-xorg-core is 1.3.0.0.dfsg-12ubuntu8.3 The radeonhd driver I downloaded and compiled it from source. It has a module version of 1.1.0.

First off, try RadeonHD git code or at least v1.1... 1.0 is VASTLY outdated...

I have updated that post as I wasn't 100% sure on the version number. It is 1.1.0. My issues was that I wasn't specifying my outputs properly.

xrandr had the following outputs:
DVI-I_1/digital
DVI-I_1/analog
DVI-I_2/digital
DVI-I_2/analog

but since my card only has 2 outputs I thought that the '/digital' and '/analog' was not part of the output identifier. I changed my xorg.conf to have the following:


Section "Device"
Identifier "device_0"
Driver "radeonhd"
BusID "PCI:1:0:0"
Option "monitor-DVI-I_1/analog" "monitor_0"
Option "monitor-DVI-I_2/analog" "monitor_1"
Option "RDROutputOrder" "DVI-I_1/analog"
EndSection


And now I am getting non-cloned screens under xorg, but still cloning on the virtual terminals, which I can live with.
