sweet, thats what im doing now too
it works great so far!!
i can run mplayer movies full screen to the other display
X is awesome, if i understand correctly, i could assign a 2nd mouse and keyboard to the 2nd screen, not link them and have a 'media center' right there on my TV screen that would potentially be totally seperate from my other desktop?
can you start 2 instances of X using different resource?
