Developers of FreeBSD are making strides in Wayland support for FreeBSD. Wayland is a display server protocol that specifies communication between display servers and clients. Check out the discussion at Phoronix in the link provided.
FreeBSD is making some progress on supporting Wayland/Weston as an alternative to running the X.Org Server.
Wayland support on BSDs and other non-Linux platforms has lagged behind, but Johannes Lundberg is one of the FreeBSD contributors working on getting things into shape.
