I'm actually impressed that they were this close to enabling it in 13.10 (and are indeed enabling it for the phone). If it is that good, they have leapfrogged Wayland with less than a year of work, and who knows what they will achieve in the next six months... but we will know how good it is only once it is being widely used 'in the wild'.

I'll be interested to see how much "technical debt" they're racking up for themselves...

They weren't *this close* to enabling Mir for 13.10, they were close to enabling X-Mir. There is a difference.

XMir runs on Mir. It is a major achievement to replace Xorg with XMir. If it were trivial, why didn't Fedora or others ship with X-Wayland as default years ago? It would have been the best way to kickstart porting to Wayland.

Because there is no benefit in doing that. You might want to read http://mjg59.dreamwidth.org/26254.html.

I assume you read it too, as well as the comments? There is a benefit to pushing (Mir/Wayland) out to users, even if they are using X(Mir/Wayland) to actually run their programs, and even if Xmir is not very different at this point from Xorg. Apart from wider testing of Mir itself, several other points are brought up in the comments.

The only point I found in the comment was that it would be technically possible to have better VT switching, but that is not enabled in the current Mir/XMir setup.

Did you find something else?

It's more accurate to say that Mir runs on XMir.

It's a bit old article, but I doubt a huge amount has changed.

Not really. XMir is a Mir client, it depends on there being a Mir server process running. It just doesn't use that Mir server for performing drawing operations.

It would be a major achievement if it had been achieved :)

You might have missed it but a short while back there was a huge flamefest because some XMir specific patches were removed from a Xorg driver.

Those patches wouldn't be necessary if XMIr ran on Mir due to Mir doing the actual input/output hardware/driver access.
