Weston
Weston is a Wayland compositor reference implementation that provides a minimal, functional environment for running Wayland clients. It serves as the standard compositor for the Wayland display server protocol, handling window management, input events, and rendering for graphical applications. Developed as part of the Wayland project, it is often used for testing, development, and embedded systems where a lightweight display server is needed.
Developers should learn Weston when working with Wayland-based systems, particularly for embedded Linux, IoT devices, or custom graphical environments where X11 is not suitable. It is essential for testing Wayland client applications, developing new compositors, or creating minimal desktop environments, as it provides a stable reference implementation that ensures compatibility with the Wayland protocol.
