Will it? There's no way to know for sure. I think it might, but I heard they rely on SDL for all the window management related stuff (not sure if it's that way, though), and if it is that way, as long as it's supported on both Mir and Wayland (Wayland support is on the way, and Mir support will likely happen if not on upstream, with out of tree patches) it won't change anything for Valve. As for latency and such, I think both Mir and Wayland are supposed to be non intrusive, so it shouldn't affect as long as they do no hackish fixes to code for one and later make it run on the other.So the questions:
1. Will all of this Wayland / MIR stuff get in the way of gaming on Linux? Politically, will it hinder the confidence of Valve and other game devs to commit i.e will you install DOTA2 on Ubuntu get 100fps and then need some conversion that reduces FPS or increases frame latency to work on Weyland.
Again, there's no way to know for sure. I doubt Valve will use Mir on their console, because that would imply they either need to code for a custom compositor or use Unity, and the first is unneeded work and the latter I think is not really what you want in a console. If I have to guess, for now they'll stick to X.org because they did the port recently and switching now could make porting to X.org seem like a wasted effort. But it's all speculation. Valve didn't make any claims on the subject, and supporting Ubuntu might just be a convenience, and if it starts implying more work, it stops being such a convenience.2. Firstly, X is here for a while longer i guess as the dust needs to settle but if STEAM is officially supported on 13.04 Ubuntu then one would assume games will be ported and tested for MIR in future. Will Weyland games run as fast as MIR ? Will people who want to game on Linux be forced to use Ubuntu ?
/*EDIT: I'm not sure if I was clear as of why I mentioned the console, so I'll clarify it now; I mention it because I think that's their priority on porting to Linux, more than the desktop market share, so they will keep things the way it's easier for them to get the console out */
As for fitting, X.org fits almost everywhere, and has been used on phones even. It's not that.3. What is wrong with X ? it seems like only the actual open source drivers and mesa improvements hold performance back from reaching windows standards? If its because X doesn’t fit tablets, cars then why should I care I want a desktop environment?
The problems with X are a lot, I'll just list the ones that come to mind, but they're all related to being designed when computers were a completely different thing than what they are now.
One of the problems is that it should be backwards compatible with software written in another era.
Another is that, for some reason I don't quite remember, enabling a tear free desktop implies breaking support for such old software.
Other problem is everything related to input handling, event management, etc.
Basically, it gets too much in the way. Here is a very complete article from not too long ago on the differences between Wayland and X.org, I think you should read it.
No question is dumb, only answers can be dumb. And the previous one can contain silly errors, BTW, I don't quite remember most of the problems with X, aside of doing a lot of things it doesn't need to do by today.Sorry for my dumb questions
