ati x700 and dual head

[brennero]

Hi gentlmen,
I'm using a laptop Acer with AMD 64, I've just installed the drivers fglrx from Livna for the Ati x700 video card. I'd like to use it in dual mode, but when I try to set the Ati control panel, plug-in the second monitor and restart both the screen get black.
Here it is my xorg.conf if can be useful

Run the command
aticonfig --help

It will list a few commands that you can use to setup your x.org. IIRC, there are two for dual head (ATI calls it big desktop). I typically use the second. I'd look it up myself, but am on a school computer.
