I'm looking at installing XBMC in Debian on a mATX PC I'll use as both a NAS and HTPC.
I am currently researching the actual components that will make up this computer and I'm considering how graphics need to be accounted for. I don't know exactly what Xorg is, technically, all I know is it's needed for graphics environments.
Anyway, I want to use XFCE on Debian but for 1080p decoding with built in Intel HD 300 graphics I assume some special drivers are needed to take advantage of this? No doubt this would 'just work' out the box on Windows, but I want to use Linux for its features that make running a NAS on it more power-user friendly.
tldr: What exactly are the technical considerations that need to be made with getting integrated graphics hardware acceleration working under Linux (Debian) environments? Must I make it work with Xorg, XFCE and the media player itself (XMBC)?
