![]() Will video drivers need to be rewritten for Wayland? Thus Wayland, from a high-level view, is about making the compositor the central process and the X server the optional add-on you can activate for legacy X applications. Most of that stuff we don't really need or use in modern desktops.Īt the same time, with today's 3D-centric desktops, toolkits, and window managers, the compositor is a critically important piece and in the future will likely become a hard requirement, yet in X11 it is limited to being merely an out-of-process extension to the X server. X11, by definition, is a big protocol of rendering primitives and font management and lots of other stuff. These days we only use a fraction of what X was originally designed to do. ![]() What is the reason for making Wayland? Why does X have to be replaced? ![]() It's possible we'll roll it out for some limited scope initially, since it may take time before it's adequately supported across a broad enough range of hardware. This decision will be made at a future Ubuntu Developer Summit (UDS). When will Wayland become the default on Ubuntu? It will be run inside the Wayland/Unity instance when needed. No, X will be retained for backwards compatibility. See the Wayland website for more details. Or, in layman's terms, it assumes you're using a 3D desktop from the start, instead of bolting on 3D capabilities to an 2D framework. Wayland is a new protocol that enables 3D compositors to be used as primary display servers, instead of running the 3D compositor as an extension under the (2D) X.org display server. It was originally written for moving Unity to Wayland *** ![]() This section likely needs a lot of review. *** We are no longer moving to Mir and now switching back to Gnome-Shell which already has a wayland implementation in it. ![]()
