Thank you that was very helpful...
In fact I have changed my xorg.conf file to one suggested for dual displays using the ATI Radeon 7500 that I am using.
From what I can see this should provide me with 1024x768 on my internal LCD and 1280x1024 for the external flat panel.
It seems that although there are no complaints with the setup the effect is exactly as before - I get both screens at 1024x768 and they are the same screen - not two desktop areas (ie being able to mouse from one to the other)
Ideally I want to run my Windows XP VM on the Internal screen at 1024x768 and still have my gentoo desktop on the larger external monitor.
I am able to invoke the screen modes by using the Fn F7 combination which switches the LCD off and the Ext On, then the Ext Off and the LCD On and finally Both LCD and Ext on...
Here is my xorg.conf - can anybody lend further insight into this configuration:

I have left the commented section at the bottom because it is the original xorg.conf that I had in place before visiting thinkwiki.
TIA
