There are two packages in BLFS that implement the X Window System: X.org and XFree86. These packages are quite similar. In fact the base system of X.org is XFree86-RC2. The primary difference as of this writing is the license provisions of the packages. For someone building a package for their own use, these issues are not significant. Most large commercial distributions have decided to use the X.org package, but several still use XFree86. A second reason for the forking of X packages is the stated goals of the developers. Some developers were unhappy with the administration and progress of XFree86. X.org's future plans include significant improvements to the internals of the system and more frequent releases. XFree86 continues to be a solid, conservitive application with excellent driver support. Both X.org and XFree86 can be installed in the same way, but this section will provide a slightly different and more current variation for installation. X.org is a freely redistributable open-source implementation of the X Window System. This application provides a client/server interface between display hardware (the mouse, keyboard, and video displays) and the desktop environment while also providing both the windowing infrastructure and a standardized application interface (API).
