NAME

default.session - GNOME Default session configuration file.

The /usr/share/gnome/default.session file contains a list of programs to be launched the first time a user logs into the GNOME environment.

The format of the file is the one used by the gnome_config libraries, and it looks like this:

[Section]
SEQID,id=uniqueID
SEQID,Priority=PRIO
SEQID,RestartCommand=command
num_clients=TOP

There are three possible names for Section And they are:

Default: This specifies the Default session to load
Chooser: Lets the user configure which non-session aware programs should be started up when the session begins

Since the gnome_config file format is not very flexible, an array of data is emulated by listing starting from 0 chunks of "id,Priority,RestartCommand", and at the end the num_clients variable lists the number of chunks listed.
The uniqueid key provides a name that is unique within this file and passed to the app as the client id which it must use to register with gnome-session.
The RestartCommand specifies the command to run from the $PATH.
The Priority determines the order in which the commands are started (with Priority = 0 first) and defaults to 50.
The clients must be numbered from 0 to the value of num_clients-1
