Default radeonhd with two monitors

I'm in the process of building my new workstation (OpenSolaris 2008.11), but am a bit stuck with configuring X to span my two monitors (3840x1200).

Graphics card: PowerColor Radeon HD 4870
Monitors: 2 x Dell 2408WFP 24" (1920x1200)

I've searched around various places and stitched together a file for /etc/X11/xorg.conf. However, using this file gives me only console log-on - if I remove the xorg.conf, I get gdm starting up, but the screen is essentially duplicated on both monitors.

Any idea where I've gone wrong? I've copied in xorg.conf below, the Xorg.0.log is here.

Thanks...

/etc/X11/xorg.conf
Code:
Section "ServerLayout"

We would really need to see the Xorg.0.log file from when you used that xorg.conf file. Instead, you gave us the Xorg.0.log file from when you didn't use an xorg.conf file at all :-)

In the future, also, please use a service like http://pastebin.com/ rather than a site that bombards users with ads and popups.

Thanks for the link to pastebin, that's really useful. I've grabbed the log from when I had the xorg.conf enabled, have dumped it here

You are currently using radeonhd 1.2.1 which just doesn't support your GPU. According to the X.Org radeonhd wiki page (http://wiki.x.org/wiki/radeonhd), RV770 support was introduced in 1.2.2. If possible, I would suggest upgrading the driver.

Have now got it all working! Some very kind help from Alan Coopersmith at Sun got me sorted out after getting stuck with compiling radeonhd on amd64. For reference, the solution can be found here

Did you get your dual monitors to work properly when X starts up? This is a pretty good wiki on xrandr 1.2, and gives a good example on modifying xorg.conf to do what you want:

I have an xorg.conf which mirrors the login screen, then a
shell script (run on login) which calls xrandr to span the two monitors.

I will post copies of both when I get home tonight.

As promised, here are the two configuration files:

/etc/X11/xorg.conf
Code:

        Identifier   "DELL2408_R"
EndSection

Section "Monitor"
        Identifier   "DELL2408_L"
        Option       "LeftOf" "DVI-I_1/digital"
EndSection

Section "Device"
	Identifier  "HD4870"
	Driver      "radeonhd"
	VendorName  "ATI Technologies Inc"
	BoardName   "RV770 [Radeon HD 4870]"
        BusID       "PCI:1:0:0"
        Option      "DVI-I_1/digital" "DELL2408_R"
        Option      "DVI-I_2/digital" "DELL2408_L"
EndSection

Section "Screen"
        Identifier "MyScreen"
        Device     "HD4870"
        DefaultDepth     24
	SubSection "Display"
		Depth	24
		Virtual	3840 1200
        EndSubSection
EndSection
dual screen startup script
Code:
#!/bin/sh
xrandr --output DVI-I_1/digital --right-of DVI-I_2/digital

I just went through a similar issue with 2 19" Dell monitors..
My work box is a Dell OptiPlex 755 (IIRC) with one of those
Funky ATI 2400 cards with the cheesy dongle..

The PC guys had a EVGA 8600 GTS that I swapped out and since
OpenSolaris seems to have better support for NVidia, it was
dead Simple..

Thx for posting the xorg.conf..
