I've heard a lot about Mir lately. It seems to be a big thing in the Ubuntu community.

What exactly is Mir and why is it so important? Will it affect me?

Mir is the next generation display server. A system-level component targeted as a replacement for the X window server system to unlock next-generation user experiences for devices ranging from Linux desktop to mobile devices powered by Ubuntu.

The purpose of Mir is to enable the development of the Next Generation Unity.

In the Linux world, the display server is the part of the software stack that handles graphics processing. In other words, it's the thing that draws pretty pictures on the screen. And for decades, there has been only one show in town when it came to display servers for virtually all open source operating systems: The X Window System, which was written in an era when the computing landscape was very different than it is now. Venerable as it is, X is not particularly well-suited to many of the devices or usage scenarios that predominate today.

So by implementing Mir, an entirely new display server that Canonical is building from the ground up, Ubuntu developers are doing something radically different. They're bringing a crucial part of the open source ecosystem into the modern age, creating a display system tailored to work well on the types of hardware—especially phones and tablets—that will define the future.

In short, is this Canonical's answer to Microsoft's "Metro" and Apple's "iOS/OS X" device cross-overs? – gravity Jun 12 '13 at 14:23
@gravity No Mir is a display server like X11 or Wayland, Metro is a GUI, and iOS/OSX are OSs, I don't know about OSX but the (roughly) Windows equivalent would be WDDM (Windows Display Driver Model). However the concept of a unified platform is the same. – Uri Herrera Jun 12 '13 at 22:25
That's much clearer to me now, thank you. Before, I was thinking it was a stylistic unification, now it sounds more of substance instead. – gravity Jun 13 '13 at 13:07

Mir will affect you in future releases of Ubuntu - by making desktop more efficient and attractive!

You can run it now if you want to, though it is still being developed and still sits on top of the X windows stack at the moment. You have to be running 13.10 though.

efficient and attractive! can your provide any cue/evidence for your answer? – Anwar Shah Apr 4 '15 at 3:35
