Thanks Alan - I think you have solved it!

Looking through the bugs I found this:

Adding i915.modeset=0 to the boot options fixed it!

This is something that is mentioned in the beta release notes

I have spent most of the morning booting it up and checking the 
/var/log/Xorg.0.log etc., looking at the bugs in Launchpad, check the 
forums before posting to this list. There are quite a few forum threads 
on ubuntuforums.org with people posting a similar problem.

Hopefully this will get sorted quickly as the Dell I have is a very 
"standard" system (you could even get in PC World) and I was 
disappointed to see the latest Ubuntu not work with it straight away.

However, I asked the question to right people, and got the answer almost 
immediately - for that you have to love the open source community :-)

Thanks Again
