gdm1

Usage

Overview

GDM is a replacement for XDM, the X Display Manager. Unlike its competitors (X3DM, KDM, WDM) GDM was written from scratch and does not contain any original XDM / X Consortium code. GDM runs and manages the X servers for both local and remote logins (using XDMCP). See http://www.gnome.org/projects/gdm/ for more details.

gdm is main executable. gdmsetup is a graphical tool for easily changing the most commonly used options.

For full documentation see the GNOME help browser under the Applications / System Tools section.

Options

gdm and thus also gdm accept the following options:

-nodaemon

Do not fork into the background

--no-console

No console (local) servers to be run

--preserve-ld-vars

Preserve LD_* variables

--version

Print the GDM version

--help

Print simple description of accepted options

gdmsetup accepts all standard GNOME options.

Configuration

Configuration is done either by running gdmsetup or by editting the /etc/X11/gdm/gdm.conf (usually, could also be /etc/gdm/gdm.conf) file. The graphical tool does not support all the options possible so editting the configuration file is sometimes necessary.
