The X.Org project provides an open-source implementation of the X Window System (“X-Windows”). The X Window System, also known simply as X or X11, is a windowing system for bitmap displays introduced in 1984 by the Massachusetts Institute of Technology (MIT). It was developed as a part of Project Athena, a joint project between MIT, Digital Equipment Corporation, and IBM. The purpose was to create a platform-independent system enabling users to access and use graphical applications on multiple types of computers and displays. The X Window System quickly became the standard for Unix-based graphical user interfaces and is still widely used today, particularly in Linux and Unix environments. It is an open-source project, meaning the source code is freely available for anyone to download, modify, and distribute.
To install the X Window System for RPM-based Linux distributions, use the following command-line syntax:
yum groupinstall "X Window System"
