Firstly, Ubuntu covers about a third of desktop Linux installations. That means that majority of desktop Linux users use something other than Ubuntu. Even on Steam, Ubuntu doesn't have the majority of users. Ubuntu may have the biggest single market share of any distro, when talking about home users desktop installations, but that means nothing.
Meanwhile, Nvidia/AMD don't really care about Steam or any of that, not at this point anyway. Maybe in the future when the market grows, with steamboxes and other Linux consoles coming to market, but right now? The real Linux money for GPU makers is in render farms and workstations. That means mostly RHEL, Suse, and the like. Not Ubuntu. RHEL will use Wayland, so when the render farms move over to Wayland, at that point, Nvidia & AMD at the very least are going to offer drivers for them. They'll have to, there's just no question about it.
Secondly, there's not going to be any "Mir drivers". There will only be EGL drivers, which can be used by both Mir and Wayland. Mir is not going to ever be used by anyone other than Canonical, because no other desktop environment is willing to adapt it, they're all going to Wayland instead. There are very good reasons for this, you could ask the KDE devs, such as Martin GršŖlin about them, or you could ask the GNOME devs, read their blogs or whatever. But it boils down to the fact that Canonical is developing Mir for the needs of Unity only. They are not thinking about other distros or desktops. They're not creating a stable protocol, they're not enabling others to reimplement Mir for themselves, they control the development and do it all in-house, without collaborating with others. This all is contrary to what Wayland does: Wayland provides a way for everyone to implement their own compositors, while providing a stable protocol, compatibility, and a development model that caters to the needs of every distro and desktop environment.
Thirdly, even in the extremely unlikely situation that the GPU makers would only offer "Mir drivers" (which, again, will not happen), but even if it did... it wouldn't matter, because Wayland supports multiple backends and runs on pretty much anything, all you have to do is implement the backend. It can already run on EGL, Android drivers, or plain CPU rendering (Pixman). It would be pretty much trivial to write a Wayland backend to allow it to run on those "Mir drivers" (which, again, will not happen).
Fourthly, Mir is a totally useless waste of resources. There's nothing it offers that Wayland doesn't. There are no technical reasons for its existence whatsoever. The only reason it exists is because Canonical wants to separate Ubuntu from other Linux systems. That's pretty much shooting themselves in the foot, as an OS that is 99% dependent on community-written code, meaning that if the community suffers, Ubuntu suffers also.
Nvidia has flat-out stated that they only care about Linux workstations, and that the only reason they release Linux desktop drivers because it doesn't take any additional work for them to do so. I trust their opinion on their own business much more than I trust you.
"The biggest reason that the professional graphics market is of great importance to NVIDIA and AMD isnít just that itís another market for them to sell products in, but because itís not just another market. As we alluded to in our introduction, going by the volume of products shipped the professional graphics market is tiny. Even looking at revenue itís far smaller than the consumer market. But what revenue hints at and what financial statements prove is that itís profitable. Extremely profitable."
Wait, you are relying on web hit statistics to measure the workstation market? Do you even know what a workstation is?EDIT2: More numbers: http://www.softpanorama.org/Articles...stations.shtml Funny enough, Ubuntu also reigns in the workstation market (three times as much as Fedora+Suse together...). Time to revise some myths?
And again, the article actually makes the exact opposite point you are claiming: "Usually only Red Hat and/or Suse are certified for the usage in large corporate environment (lately Ubuntu joined them in some corporations)."
In fact, Ubuntu has been intentionally snubbing workstations, cutting out things like GIMP explicitly because they are important for workstations but not for consumer desktops.
BTW, I don't know if it was you or someone else who said drivers don't deal with Mir or Wayland directly. If that's the case and drivers will target both display managers at the same time no matter what, who the hell cares? If this is not true and Nvidia/AMD have to make a decision, I'm positive they'll support what becomes more popular IN THE REAL WORLD, not in linux-geeks-land. That's Mir, obviously.
