MDM.8(8) Debian GNU/Linux MDM.8(8)NAMEmdm - MDM Display Manager
SYNOPSISmdmDESCRIPTIONmdm is the equivalent of xdm(1x) or wdm(1x), but uses the GNOME
libraries to provide a GNOME look-and-feel. It provides the GNOME
equivalent of a "login:" prompt.
mdm reads /etc/mdm/mdm.conf for its configuration. For each local
display, mdm starts an X server and runs mdmlogin(8x) on that display.
The main mdm process also listens for XDMCP requests from remote
displays. These requests can either be direct, causing mdm to start a
mdmlogin(8x) on the remote display, or indirect, causing a
mdmchooser(8x) to be opened.
When managing a display, mdm attempts to execute /etc/mdm/Init/display,
or /etc/mdm/Init/Default if that does not exist. When a user logs in,
mdm first attempts /etc/mdm/PreSession/display (or
/etc/mdm/PreSession/Default), and then one of the sessions in
/etc/mdm/Sessions. When the session has completed, mdm attempts to run
/etc/mdm/PostSession/display, or /etc/mdm/PostSession/Default. Of all
these files, only the /etc/mdm/Sessions one is required to exist.
mdm maintains information about the displays it is managing in
/var/lib/mdm. This includes xauth information, so this directory is not
readable to normal users.
mdm uses PAM to perform authentication using the config file
/etc/pam.d/mdm.
