                                                | Chapter 18. X (Topic 2.10)Unix has a long history of utility that                    predates the popular demand for a graphical user interface (GUI).                    However, a GUI is an essential part of running small systems                    today, and the standard GUI on Linux systems is the X Window System, or more                    simply, X. Originally developed at MIT and Digital Equipment                    Corporation, X's current release is Version 11 Release 6. This                    version is more commonly referred to as X11R6, or just X11. X is a complete                    windowing GUI and is distributable under license without cost.                    The implementation of X for Linux is XFree86 (http://www.xfree.org/), which is available                    for multiple computer architectures and is released under the                    GNU Public License. This section covers these four Objectives                    on XFree86 for LPI Exam 102:                       Objective 1: Install and                      Configure XFree86                                           Most distributions install XFree86 when                      Linux is installed, but a number of the configuration                      details are important for Exam 102. This Objective covers X                      servers, fonts, and automated XFree86 configuration tools.                      Weight: 4. Objective 2: Set Up                      xdm                                           This Objective covers the X display                      manager, a graphical login system. Weight: 1. Objective 3: Identify and                      Terminate Runaway X Applications                                           Sometimes an X application becomes                      unresponsive or fails to terminate normally. This Objective                      mentions methods to cope with these situations. Weight: 1                      Objective 4: Install and                      Customize a Window Manager Environment                                           This Objective covers the selection and                      customization of X window managers, including menus, X                      terminals, X library issues, and a number of control files.                      Weight: 4.    |  |  |
