Of course it should just work! Xorg 7.3 is included in Gutsy but I guess there are more job required to get the tools to support it (the screen admin tool in Gutsy is an example) before it works out of the box. Until then I guess it’s the hakkerty-hakk way :(
I gave it a try in Gutsy and it was better than ever but not totally usable.. But as I said, we are getting there!
