A Display Server is a software component that manages the display output for graphical user interfaces on computers. It handles the rendering of windows, graphics, and user interactions, allowing multiple applications to share the screen space effectively. Display servers are essential for providing a smooth visual experience in operating systems like Linux. There are different types of display servers, such as X11 and Wayland. Each has its own architecture and features, impacting performance and compatibility with various applications. Display servers communicate with both the hardware and the applications, ensuring that visual elements are displayed correctly and efficiently.
