Question Extended desktop on ThinkPad T42


Hi Guys,
I am an Linux newbie in a big way but have enough knowledge to follow the bouncing ball. lol
The problem I have is I'm trying to extend my desktop, (dare I say it) windows style, to an external monitor plugged into a ThinkPad T42. At the moment when I boot up with the monitor connected it initially comes up cloning the laptop screen. Using the "Fn-F7" I can switch between the various combinations but they will only still display a copy of what fits on the laptop's LCD, however it displays black bars down the side of the image on the external monitor probably due to a resolution setting issue.
My system details are,
Ubuntu Fiesty Fawn 7.04
I'm pretty sure the graphics card is an ATI Radeon 9600
The output of a $ lspci
"01:00.0 VGA compatible controller: ATI Technologies Inc Radeon Mobility M7 LW [Radeon Mobility 7500]"
Resolution of the external monitor - 1280x1024@75Hz
Resolution of the laptop LCD - 1024x768@60Hz

I've been following a few discussion threads that say to modify the xorg.conf file and thankfully I remembered to back it up cause I've broken xserver several times trying the changes.
I do think the answer lies in the xorg.conf file however there is obviously something I am missing here and it's not playing the game.
Your assistance is appreciated.
Cheers
Dave

xorg.conf

Here is a copy of my xorg.conf if that might help. It's a fresh one created from $ sudo aticonfig --initial
Can anyone help me with my question or am I in the wrong forum? If you need more information let me know and I can get it.
Cheers

xorg.conf for IBM Thinkpad T42 laptop with DUAL HEAD and OpenGL

From: http://www.abmh.de/en/papers/linux/t...on-opengl.html

xorg.conf for IBM Thinkpad T42 laptop with DUAL HEAD and OpenGL
I spend some time to configure my T42 laptop to used dual head together with OpenGL. I used MergedFB with MergedNonRectangular. Google Earth works ;-) xine only on the LCD-screen... Here is the result. If you have any questions or ideas for improvements, do not hesitate to contact me at http://www.abmh.de/msg.html. The config-file and a log-file of the X-start-up sequence is included in the zip-package. I also tried a wide screen (1600x900) but I don't get it working.
