writes "Delays keep piling up for the Mir display server on the Ubuntu desktop. After already being postponed multiple times, Mir might not be enabled by default on the Ubuntu Linux desktop until the 16.04 LTS release — in two years time! This was the estimate by Mark Shuttleworth in a virtual Ubuntu Developer Summit. Using Mir, Mark says, will lead to supporting more hardware, obtaining better performance, and 'do some great things' with the technology. He expects some users will start using Mir on the desktop over the next year. Mir is already packaged as an experimental option, along with an experimental Unity 8 desktop session."
