Which component communicates with the Linux operating system to manage UI requests?

The Display Server is the component responsible for communicating with the Linux operating system to manage user interface (UI) requests. It acts as an intermediary between the graphical applications and the hardware, typically managing how graphical outputs are displayed on the screen. The Display Server handles input from devices such as keyboards and mice and routes this information to the appropriate applications, enabling users to interact with the system visually.

In a Linux environment, common display servers include X11 and Wayland. They determine how windowing and graphics are managed, asserting control over how graphics are rendered and ensuring that they respect the user’s graphical preferences defined in the Desktop Environment. Consequently, the Display Server plays a crucial role in facilitating the graphical interface that users interact with, making it essential for proper functionality of the UI.
