NAME

gnome-session - Start the GNOME desktop environment  

SYNOPSIS

gnome-session [-a|--autostart=DIR] [--session=SESSION] [--failsafe|-f] [--debug] [--whale]  

DESCRIPTION

The gnome-session program starts up the GNOME desktop environment. This command is typically executed by your login manager (either gdm, xdm, or from your X startup scripts). It will load either your saved session, or it will provide a default session for the user as defined by the system administrator (or the default GNOME installation on your system).

The default session is defined in gnome.session, a .desktop-like file that is looked for in $XDG_CONFIG_HOME/gnome-session/sessions, $XDG_CONFIG_DIRS/gnome-session/sessions and $XDG_DATA_DIRS/gnome-session/sessions.

When saving a session, gnome-session saves the currently running applications in the $XDG_CONFIG_HOME/gnome-session/saved-session directory.

gnome-session is an X11R6 session manager. It can manage GNOME applications as well as any X11R6 SM compliant application.  

OPTIONS

The following options are supported:

--autostart=DIR

Start all applications defined in DIR, instead of starting the applications defined in gnome.session, or via the --session option. Multiple --autostart options can be passed.

--session=SESSION

Use the applications defined in SESSION.session. If not specified, gnome.session will be used.

--failsafe

Run in fail-safe mode. User-specified applications will not be started.

--debug

Enable debugging code.

--whale

Show the fail whale in a dialog for debugging it.

 

SESSION DEFINITION

Sessions are defined in .session files, that are using a .desktop-like format, with the following keys in the GNOME Session group:

Name

Name of the session. This can be localized.

RequiredComponents

List of component identifiers (desktop files) that are required by the session. The required components will always run in the session.

Here is an example of a session definition:

[GNOME Session]
Name=GNOME
RequiredComponents=gnome-shell;gnome-settings-daemon;

The .session files are looked for in $XDG_CONFIG_HOME/gnome-session/sessions, $XDG_CONFIG_DIRS/gnome-session/sessions and $XDG_DATA_DIRS/gnome-session/sessions.  

ENVIRONMENT

gnome-session sets several environment variables for the use of its child processes:

SESSION_MANAGER

This variable is used by session-manager aware clients to contact gnome-session.

DISPLAY

This variable is set to the X display being used by gnome-session. Note that if the --display option is used this might be different from the setting of the environment variable when gnome-session is invoked.

 

FILES

$XDG_CONFIG_HOME/config/autostart $XDG_CONFIG_DIRS/config/autostart /usr/share/gnome/autostart

The applications defined in those directories will be started on login. gnome-session-properties(1) can be used to easily configure them.

$XDG_CONFIG_HOME/gnome-session/sessions $XDG_CONFIG_DIRS/gnome-session/sessions $XDG_DATA_DIRS/gnome-session/sessions

These directories contain the .session files that can be used with the --session option.

$XDG_CONFIG_HOME/gnome-session/saved-session

This directory contains the list of applications of the saved session.
