Hi Everyone,

As many of you will know, the Mir team had two core goals for the Ubuntu 
13.10 cycle:

1. Deliver Mir + XMir + Unity 7 on the desktop for those cards that 
supported it, and fall back to X for those that don?t.
2. Deliver a native Mir + Unity 8 running on Ubuntu Touch images and 
devices.

Unfortunately, due to some outstanding technical difficulties, we can 
only achieve the latter of these two goals.

While we are on track to successfully deliver Mir for Ubuntu on 
smartphones, we are unfortunately not going to be able to deliver Mir + 
XMir + Unity 7 as the default experience on the desktop.

Mir has made tremendous progress and is currently available on the 
Ubuntu archive for use, but there are still some outstanding quality 
issues that we want to resolve before we feel comfortable turning it on 
by default. Many of these issues live in the XMir part of the stack, 
which provides the integration between the X server and the underlying 
Mir system compositor. More specifically, the multi-monitor support in 
XMir is working, but not to the extend we'd like to see it for all of 
our users. The core of Mir is working reliable, but with XMir being a 
key component for our 13.10 goals, we didn?t want to compromise overall 
Ubuntu quality by shipping it.

Mir & XMir are available from the archive as an optional configuration, 
but XMir won't be part of the default configuration.

I know many of you have been curious about the progress of discussions 
with GPU manufacturers about Mir support, and while those conversations 
are under NDA, I can assure you they are progressing forward.

We have compiled a Q&A which can be found at 
https://wiki.ubuntu.com/Mir/13.10/NoDefaultQ%26A

If you have any further queries, please feel free to reach out to me or 
my team, and feel free to discuss this in more detail either here or on 
mir-devel (https://lists.ubuntu.com/archives/mir-devel/).

best,
Olli
