I had trouble trying to get the SDK going too - used to Windows and developing in Visual Studio but keen to have a go at development for my soon to be delivered 770. Installin Ubunto was easy, getting the SDK going was beyond me at my first attempt!

We could really do with a step by step guide - anyone up to doing this?

I did manage to get the Live CD version going - more details here - but this has yet to be updated for the 1.1 RC
