Wayland
Wayland is a modern display server protocol and communication standard for Linux and Unix-like operating systems, designed to replace the older X Window System (X11). It provides a simpler, more secure, and efficient method for graphical applications to communicate with the display hardware and compositor. Wayland enables direct rendering by clients, reducing complexity and improving performance in window management and graphics handling.
Developers should learn and use Wayland when building or maintaining graphical applications for Linux desktops, as it is becoming the standard for modern distributions like GNOME and KDE Plasma. It is particularly valuable for applications requiring smooth animations, touchscreen support, or enhanced security through client isolation. Wayland is essential for developers working on embedded systems, IoT devices, or any project where low-latency graphics and resource efficiency are critical.
