Mark Shuttleworth announced on his blog today that Unity will be embracing the X Window System replacement Wayland, the OpenGL based display management system. In his own Words
The next major transition for Unity will be to deliver it on Wayland, the OpenGL-based display management system. We’d like to embrace Wayland early, as much of the work we’re doing on uTouch and other input systems will be relevant for Wayland and it’s an area we can make a useful contribution to the project.
