Wayland 是一种 Linux 协议和显示服务器，旨在成为 X 窗口系统（通常称为 X11）更简单、更现代的替代方案。它促进了显示服务器与其客户端（应用程序）之间的通信，以渲染图形输出。
Wayland 的主要功能:
1. 简单： Wayland 的设计比 X11 更简单明了，可减少复杂性和潜在的安全漏洞。
2. 性能： 它减少了渲染的开销，允许客户端直接与合成器通信，从而带来更流畅的图形和更低的延迟，从而提供更高的性能。
3. 合成： Wayland 将合成集成到显示协议中，从而可以更高效地处理窗口和图形效果。
4. 安全性: 有了 Wayland，每个应用程序都是独立的，这有助于最大限度地降低一个应用程序干扰另一个应用程序的风险，从而提高安全性。
5. 现代图形: 它的设计利用了现代图形硬件和应用程序接口，使其适用于当前和未来的应用程序。
尽管 X11 仍在广泛使用和支持，但许多桌面环境（如 GNOME 和 KDE）都在逐步采用 Wayland。过渡到 Wayland 有很多好处，但在与某些应用程序和硬件的兼容性方面可能仍有一些挑战。
Wayland is a protocol and display server for Linux that aims to be a simpler and more modern alternative to the X Window System (commonly known as X11). It facilitates the communication between a display server and its clients (applications) to render graphical output.
Key Features of Wayland:
1. Simplicity: Wayland is designed to be more straightforward than X11, reducing complexity and potential security vulnerabilities.
2. Performance: It provides better performance by reducing the overhead of rendering and allowing clients to communicate directly with the compositor, which can lead to smoother graphics and lower latency.
3. Compositing: Wayland integrates compositing into the display protocol, allowing for more efficient handling of windows and graphical effects.
4. Security: With Wayland, each application is isolated, which helps improve security by minimizing the risk of one application interfering with another.
5. Modern Graphics: It is designed to take advantage of modern graphics hardware and APIs, making it suitable for current and future applications.
Many desktop environments, like GNOME and KDE, are gradually adopting Wayland, although X11 is still widely used and supported. Transitioning to Wayland offers benefits, but it may still have some compatibility challenges with certain applications and hardware.
