Does Cannonical take the code that goes into XWayland into their XMir fork?

They said back in October that multi-monitor support was not reliable, so maybe this new patch could help a lot.

XWayland is rootless. That means that any X window will become a Wayland window for the Wayland compositor.

Up to now, XMir doesn't work like that: there is a root X window (all windows are son of this window, and are drawn onto it), and Mir displays this root window.
Your X desktop work like that (expect the root window is directly the screen buffer)

Then you can deduce multi-monitor support is quite different for the two models.

I didn't knew Canonical did this (and I wonder why, I guess for simplicity). How does the Mir compositor combine the X root window and Mir buffers/windows?

The DDXs are in charge of allocating the buffers for the screen, the pixmaps, etc.
XMir has patches to the DDXs to use Mir to get the buffers.

So is Xwayland ready for production? i know Redhat, has some huge patch set's for it.

I don't know what patches you have in mind.

I think XWayland would be ready when the remaining input issues are fixed (mouse has issues with games for example), and that the Present extension is supported.

Most are for GDM, and, Gnome so i don't think it's a big deal.

Let's hope XWayland makes it into 1.16 in July. With Gnome 3.12 finishing up their Wayland port in April and NVIDIA maybe having all the EGL stuff ready it would suck to need out-of-tree patches for X.

Be cool if canonical supported wayland instead of forking their own. They could be benefiting the entire Linux community and not just Ubuntu.

They did. Then the lingering ghost of Steve Jobs appleized Mark Shuttleworth, and the end result of that was the unrest called Mir.
