    i might be wrong but this is what i understand about it.
    By running XMir, they still require DDX drivers in order to get 2D acceleration. They are still running the same 3D Mesa drivers. The only difference is that Mir (i think) is handling mode setting now. I'm not even certain about that.

    Oh, and of course the proprietary drivers still only work with X. Which means that Ubuntu has to complicate things and run Mir + XMir sometimes and just X others, and makes a huge mess out of everything.

      Mir simply uses Mesa/DRI2 drivers but with a small yet unsupported patch to add a Mir back-end to Mesa.

        Not for me.

        Mir is a joke (a bad one).

          i dont see what is so complicated.
          when botting ubuntu detects what drivers are you running and loads either mir + xmir or x.org, im i wrong?

            canonical claims they should have the closed source ones before 14.04 untill then when your using closed source you will fallback to pure X, so id you only care about performance you got NOTHING to worry about since you will be running pure X.
            Oh, the same drivers you use with X.org. So, where's the point of using XMir, again?
            I use only open source drivers.

            Isn't that handled by the kernel drivers?

                  No, that's not a good reason at all. Currently X is still a lot better supported when it comes to drivers.

                    There is no race, and there has never been one. Ubuntu is going to use Mir, everyone else is going to use Wayland. Canonical is just rushing Mir for their own needs, and others are waiting for DEs to gain Wayland support before switching to it.

With Wayland, there's a stable protocol that allows developers to write their own Wayland compositors, which can run Wayland natively, so there's no need for kludgy hacks like running a DE on XMir is.
                    That's true, and I've been thinking the same thing. The reason why Canonical is pushing XMir is because they have nothing like Weston. You can't run X applications on Mir without the whole DE running on XMir. On Wayland, you can, thanks to Weston.

                      But X11 is not developed by Canonical! Get yourself in the mind of a fanboy and you might understand why using the same drivers for XMir on Mir is better than just using X.

                        It's handled by KMS in the kernel, yes, but the question is what calls into KMS from userspace. X or Mir?

                          Sure, but i don't see how that makes the driver situation any better than the old way of doing things. If anything it's worse - which means i think that's a poor reason to use when asked about why XMir should be used for the whole DE like Ubuntu is doing.

                            Mir is not really doing any thing at all what you're getting is Xmir it the same at opening a window using Wayland on top of Xorg no point at all in doing this maybe on a Developer Level but Mir is not ready for that at all it's maybe a year away from the looks of it This Xmir Thing PR and to put the Blame on Nvidia intel Mesa and AMD for no Driver Support any one remember Ubuntu Releasing Unsupported Xorgs?

                            Put Window here is all you're getting from Mir when Wayland/Weston can run as a DE and DS and do what you want it to

                              There isn't any technical reason to go Mir, having Wayland as an option, nor to go XMir in any case.

                              I guess Mir.

                                If true, then i guess it's a good way to get some beta testing of their modesetting code in Mir.

                                Still doesn't seem like a good reason to switch the whole default DE in Ubuntu over to XMir, though. That kind of thing should be handled by a beta program.
