"Why is this interesting? Well, Wayland, a lightweight display
server which is supposed to deliver a better user experience, with
smooth graphics and effects, gets closer to becoming default in
Ubuntu (Mark Shuttleworth announced that Ubuntu will switch to
Wayland in a few releases). It's still unsure when Ubuntu will make
the switch to Wayland, but it will definitely be some time after
Ubuntu 12.04 LTS. By the way, MeeGo and Fedora are likely to switch
to Wayland too."
