Bring up X without an xorg.conf and use xrandr or the gnome monitors control panel to enable multi-head. E.g., xrandr --auto xrandr --output DisplayPort-0 --right-of DisplayPort-1 etc. Make sure that works first before trying to use zaphod mode. Post the output of xandr without an xorg.conf here if that doesn't work.
