The X Display Manager (XDM) is the default display manager for the X Window System. It is a bare-bones X display manager. It was introduced with X11 Release 3 in October 1988, to support the standalone X terminals that were just coming onto the market. It was written by Keith Packard.

Functions

[edit]

XDM is used to boot an X.org based desktop environment.[2] It can control a display directly or indirectly in order to start an X session and supports remote login.[3] XDM is initialized on system startup.[4]

It can be edited through the use of a configuration file, modules, or scripts.[5][6] The configuration file is usually found in /usr/lib/X11/xdm/xdm-config.[7]

History

[edit]

XDM is one of the earliest display managers for Linux.[4] It was developed by Keith Packard after he joined the X Consortium due to his frustration using a text-based environment to try and configure X.[8]

XDM is available but unused on most systems because of its rudimentary nature.[9] Desktop environments released afterwards tended to include their own display manager, such as dtlogin on CDE.[3]
