Wayland Wayland Wayland is a replacement for the X11 window system protocol and architecture with the aim to be easier to develop, extend, and maintain Wayland is the language (protocol) that applications can use to talk to a display server in order to make themselves visible and get input from the user (a person) A Wayland server is called a
Wayland Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a Wayland client itself The clients can be traditional applications, X servers (rootless or fullscreen) or other display servers
Wayland Architecture - freedesktop. org Wayland Architecture A good way to understand the wayland architecture and how it is different from X is to follow an event from the input device to the point where the change it affects appears on screen This is where we are now with X: The kernel gets an event from an input device and sends it to X through the evdev input driver The kernel does all the hard work here by driving the device

Wayland FAQ - freedesktop. org Wayland doesn't have to compete with other projects for drivers and driver developers, it lives within the X org, mesa and drm community and benefits from all the hardware enablement and driver development happening there
Wayland Protocol and Model of Operation - Wayland Wayland Protocol and Model of Operation Basic Principles The Wayland protocol is an asynchronous object oriented protocol All requests are method invocations on some object The requests include an object ID that uniquely identifies an object on the server Each object implements an interface and the requests include an opcode that identifies which method in the interface to invoke The
Wayland Architecture - Wayland The Wayland protocol lets the compositor send the input events directly to the clients and lets the client send the damage event directly to the compositor: Wayland architecture diagram The kernel gets an event and sends it to the compositor This is similar to the X case, which is great, since we get to reuse all the input drivers in the kernel
X11 Application Support - Wayland Therefore, Wayland compositors should use Xwayland, the X11 server that lives in the Xorg server source code repository and shares most of the implementation with the Xorg server Xwayland is a complete X11 server, just like Xorg is, but instead of driving the displays and opening input devices, it acts as a Wayland client
