Xfree86

Xfree86 is an open-source software system that provides the fundamental framework for displaying graphics and managing user interfaces on Unix-like operating systems, including Linux. It acts as a bridge between the computer's hardware, like graphics cards and monitors, and the software applications you're using. By handling the drawing and rendering of windows, icons, and other visual elements, Xfree86 enables a graphical user interface (GUI) to function smoothly. It serves as the core component of many desktop environments, allowing users to interact visually with their computer's resources effectively.
