GDM(1) The GNOME Display Manager


gdm [options]
gdmsetup [options]


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 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.


gdm and thus also gdm accept the following options:
Do not fork into the background
No console (local) servers to be run
Preserve LD_* variables
Print the GDM version
Print simple description of accepted options

gdmsetup accepts all standard GNOME options.


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.


GDM is being written and maintained by George (Jiri) Lebl <[email protected]> based on the original codebase by Martin K. Peterson <[email protected]>.
