FreeBSD uses X11 to provide users with a powerful graphical user interface. X11 is an open-source implementation of the X Window System that includes both Xorg and XFree86™. FreeBSD versions up to and including FreeBSD 4.11-RELEASE and FreeBSD 5.2.1-RELEASE will find the default installation to be XFree86, the X11 server released by The XFree86 Project, Inc. As of FreeBSD 5.3-RELEASE, the default and official flavor of X11 was changed to Xorg, the X11 server developed by the X.Org Foundation.
This chapter will cover the installation and configuration of X11 with emphasis on Xorg.
For more information on the video hardware that X11 supports, check either the Xorg or XFree86 web sites.
