A display server is a software component that manages the display of graphical user interfaces on a computer. It acts as an intermediary between the operating system and the hardware, handling tasks like rendering images and managing input from devices such as keyboards and mice. This allows multiple applications to share the screen and interact with user inputs efficiently. In modern computing, display servers can be part of systems like X Window System or Wayland. They enable features such as window management, compositing, and support for various display devices. By coordinating these elements, display servers enhance the overall user experience in graphical environments.
