Unity 8 – the next major version of the Unity desktop – has been demoed running atop of Mir, Ubuntu’s custom display server.
Both Unity 8 and Mir are still in active development, so to see them running as well as they are in the video below, taken by Michael Zanetti, is exciting stuff.
Unity 8, formerly known as ‘Unity Next’ is expected to arrive as the default desktop in Ubuntu 14.04. The version of Unity 8 demoed above is not the finished article; so expect something more desktop-like when it arrives.
Ubuntu 13.10, due October this year, is likely to include an option to try both Unity 8 and Mir, though neither will be default.
