Weird Dual-Display behavior with ATI HD4670 in openSUSE


Fairly new to linux. I know that dual-display problems are common, but I've not found anything searching through various forums that has helped to solve my problem.

I've installed openSUSE 11.1 on my machine which has an ATI HD4670 connected to two identical lcd displays (each set at 1680x1050). I've installed the proprietary ATI driver, and I've spent the last three days trying to get dual display working. I think I'm getting close. This is the weird part: The second display appears to be enabled, but no desktop is present there. I say this because I can move my mouse cursor around in the second monitor, but the cursor changes to an 'X', and the screen is blank otherwise.

I've played around quite a bit with various options in the aticonfig tool. including the following commands (some of which I had to later undo by restoring the old xorg.conf file):

aticonfig --initial=dual-head --screen-layout=right
(This is what finally partially enabled
the second display)

aticonfig --dtop=horizontal
aticonfig --xinerama=on
aticonfig --adapter=all --initial


my xorg.conf file seems a little weird as well. I have two Monitor sections which look completely different The identifier for the first is "Monitor[0]"; the second is "aticonfig-Monitor[0]-1". Same scenario with Device: "Device[0] & "aticonfig-Device[0]-1".

Here is my xorg.conf file:
