| 2. The Procedure This section details the procedure for setting up Xterminal using XDMCP. The pre-requisite is to have a (any) Linux distribution installed and running X. 2.1. Before you begin, some background Before you begin, it is better to have a basic understanding of how this works. (More details are at the Resources below and LDP HOWTO page) The X server is usually started from the X Display Manager (DM). Almost all the Linux distributions include the xdm, kdm and gdm to you as your choices. (This document will use gdm and kdm as an example). The Display Manager provides a nice and consistent interfaces for general users (X-based login, starting up a window manager, clock, etc.). X Display Manager manages a collection of X displays, which may be on the local host or remote servers. It is worth noting that the Xsession file is what runs your environment. When xdm runs, it offers display management in two different ways. It can manage X Server running on the local machine and specified in "Xservers", and/or it can manage remote X Servers (typically Xterminals) using XDMCP as specified in the "Xaccess" file. (refer to the xdm man page). For kdm (which comes with the KDE desktop), it is a replacement of xdm and configures the same way, except its files are in /etc/X11/kdm in Caldera, /etc/kde/kdm in Red Hat and /usr/share/config/kdm in Mandrake. The gdm (Gnome Display Manager) is a re-implementation of the well known xdm. gdm has similar functions to xdm and kdm, gdm is the Gnome Display Manager, and its configuration files are found in /etc/X11/gdm/gdm.conf. The gdm.conf file contains sets of variables and many options for gdm, and the Sessions directory contains a script for each session option; each script calls /etc/X11/xdm/Xsession with the appropriate option. gdm has similar functions to xdm and kdm, but was written from scratch and does not contain any original XDM / X Consortium code. RH 8.0 introduces the new graphical interface called "Bluecurve". The new interface is aimed for XP feel and styles. The setup makes no difference in this case!
