“Well the surprises just keeps mounting. After shocking everyone
with the announcement that Ubuntu 11.04 will have Unity on the
desktop instead of GNOME Shell, Mark Shuttleworth announced another
possibly bigger change – Unity is going to use Wayland
display server instead of X. This will not be implemented in Ubuntu
11.04 though“This is what Shuttleworth wrote:
“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.”
