Dual Screens in X - not quite there - help please!

Hi Guys,

I have adapted a working multi screen setup I had working on my IBM ThinkPad R51 to use Xinerama and a merged desktop with the external Flat Panel LCD as the screen to the right of the laptop display.

Now I have a macbook pro with the ATI 1600 running 1680 x 1050 on the laptop display and want to get something like 1024 x 768 on the external monitor.

I can get my X server to launch gnome with the wider desktop showing in the desktop navigator (rectangular rather longer than the normal widescreen laptop single layout I am used to). But the monitor just says "no signal" and goes off.

The external display is mirroring the laptop when in text console frame buffer mode so I know the output (DVI->D-SUB adapter on the side of the mac) is working...

Can someone please have a look at my xorg.conf and tell me why the monitor might be dropping out?

Code:
stardotstar@spitfire /opt/ati/bin $ cat /etc/X11/xorg.conf

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg

another little bit of info:

When I use my dual screen config I find that fglrx doesn't load:

Code:
stardotstar@spitfire ~ $ /opt/ati/bin/fglrxinfo 
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
display: :0.0  screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org

and dri fails:
