While I'm planning my new system the possibility of a dual display arises (at very little cost as far as I can see). Does Linux support dual displays and, if so, in what sort of way does it do it?
I going to go very 'main stream' by choosing an AMD Dual Core processor and Nvidia graphics unless there's a very good reason to choose anything else. (I might be persuaded to go 'all Intel' with a Core 2 Duo processor if there are good reasons for doing so though)
