       gnome-session - Start the GNOME desktop environment


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


       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

       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

       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.


       The following options are supported:

              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

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

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

              Enable debugging code.

              Show the fail whale in a dialog for debugging it.


       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.

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

              List of task providers that are required by the session.  A  default  provider  for
              each  task  has  to be defined with a DefaultProvider-TASK key; the provider can be
              overridden by required components, the saved session or autostart applications. The
              task providers will always run in the session.

              Identifier (desktop file) of the default provider for TASK. If no provider for TASK
              is found in the required  components,  the  saved  session  and  in  the  autostart
              applications, the default provider will be started.

       Here is an example of a session definition:

           [GNOME Session]
           Name=GNOME fallback

       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.


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


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


              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.


       $XDG_CONFIG_HOME/config/autostart                        $XDG_CONFIG_DIRS/config/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

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


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