It’s now possible to login to a Unity 8 session in the latest development builds of Ubuntu 14.04. Well, in theory that is. More on that further down. It has long been the plan to offer a ‘developer preview’ of Unity 8, running on Canonical’s in-house display server Mir, in the next desktop release of Ubuntu. But the packages providing this feature have only been made available for users to install this week. The optional login aims to give users of the upcoming Ubuntu release an easy way to access, evaluate and toy with the Unity 8 interface ahead of its tentative arrival by default in Ubuntu 14.10 later this year.
