radeonhd and dualhead with HD 3470

[aronadaal]

Hello,

I'm trying to use my ATI HD 3470 (with two DVI-Out ports) in dualhead mode but I'm not able to. I'm using the radeonhd drivers, build from the repository.

First some config files and xrandr output:

I want to use a analog TFT (1280x1024, Belinea) connected to DVI 1 (via an adapter) and a digital Widescreen TFT (1680x1050, Samsung) connected to DVI 2. I set up the xorg.conf like above but I only get a picture on the Monitor connected via the analog adapter.

I tried xrandr with the following parameters

xrandr --verbose --output DVI-I_2/digital --left-of DVI-I_1/analog

but I'dont get feedback on the TFT as well as from the xrandr tool.

Can anyone please help me?
Bye,

well... there are some bugs in my xorg.conf
I fixed them, but it is still not possible to get a picture on the digital TFT!

fixed xorg.conf
