Wayland is a protocol for a compositor to talk to its clients, as well as a library implementing this protocol
Compared to the X protocol, Wayland aims to be simpler and more efficient. Here are some advantages of using Wayland over the traditional X server system:
1. **Improved Performance:** Wayland is designed with modern hardware and software technologies in mind, allowing for better utilization of system resources and improved overall performance. It reduces latency and provides smoother user interface interactions.
2. **Simplified Architecture:** Wayland simplifies the graphics stack by eliminating the need for a separate window manager and compositor. It integrates the display server and compositor into one, leading to a more streamlined and efficient system.
3. **Enhanced Security:** Wayland offers improved security features, such as isolating applications from each other. This means that one application cannot access the memory of another application, providing a more secure environment, especially for systems where security is a top priority.
4. **Better Handling of Graphics Hardware:** Wayland provides better support for modern graphics hardware and features, such as hybrid graphics and high-DPI displays. It is more capable of handling diverse and advanced hardware configurations.
5. **Smoother User Experience:** Due to reduced input latency and efficient rendering, users often experience a smoother and more responsive interface when using Wayland. This is particularly noticeable during tasks that involve a lot of graphical elements or animations.
6. **Standardized Protocols:** Wayland defines a standard protocol for communication between the compositor and its clients. This standardization helps in creating consistent user experiences across different Wayland-based desktop environments.
7. **Easier Development and Debugging:** Wayland's codebase is considered to be more maintainable and easier to work with compared to the aging codebase of X.Org. This can lead to faster development and easier debugging of issues, resulting in a more stable system.
8. **Adaptability to Modern Computing Needs:** Wayland is designed with modern computing needs in mind, including touchscreens, mobile devices, and other emerging technologies. It can adapt more easily to new hardware and usage scenarios.
However, it's important to note that while Wayland offers these advantages, it might not be suitable for every use case. Compatibility with X applications is still a consideration, although there are compatibility layers like XWayland to run X applications on a Wayland desktop. Additionally, the choice between Wayland and X server often depends on the specific requirements and preferences of the user or the distribution maintainers.
