       console-kit-daemon - ConsoleKit daemon

       console-kit-daemon [--debug] [--help] [--no-daemon] [--timed-exit]

       console-kit-daemon  is a	service	for defining and tracking users, login
       sessions	and seats.  It provides	interfaces for managing	switching ses-
       sions  and session migration when using mechanisms such as Virtual Ter-
       minals (VT).  ConsoleKit	provides a number  of  interfaces  to  specify
       what displays are managed by the	display	manager, and how.

       ConsoleKit maintains a database of which	users are logged into the sys-
       tem.  ConsoleKit	groups sessions	by seats  which	 represent  a  set  of
       hardware	 (usually  a  keyboard	and mouse).  Other process communicate
       with ConsoleKit via D-Bus.

       One session leader process is responsible for asking console-kit-daemon
       to  open	 a new session.	 In the	typical	case, the session leader would
       be a ConsoleKit enabled display manager,	 such  as  GDM.	  This	leader
       makes  a	connection to the D-Bus	system bus and asks console-kit-daemon
       to open a session when needed.

       If the operation	succeeds, console-kit-daemon will return a  cookie  to
       the  session  leader.  The session leader should	store this variable in
       the environment as XDG_SESSION_COOKIE so	that it	may be shared with its
       child  processes.   The	environment variable contains the UUID used to
       tie processes to	a session.

       At this point the session will be registered with ConsoleKit and	a par-
       ticular	set of information about the session will be stored along with

       The Session will	remain open until the Session Leader disconnects  from
       the  D-Bus  system  bus.	The session will be removed from its seat, and

       Various other programs need to know information about running user ses-
       sions,  such  as	 the  Fast User	Switch Applet and other	mechanisms for
       switching the console to	use a different	 VT  display.	Such  programs
       make  use  of  ConsoleKit  interfaces to	determine if user switching is
       supported and to	manage the switching of	different sessions on the same

       ConsoleKit  provides  a	pam_ck_connector  so that non-graphical	logins
       (e.g.  telnet, ssh, etc.) are registered	with ConsoleKit.   This	 func-
       tionality  works	 if this PAM module is enabled in the pam.conf(4) con-
       figuration.  Thus ConsoleKit can	be used	 as  a	utmp/wtmp  replacement
       since it	stores a superset of the information as	in the utmp/wtmp data-

       The ConsoleKit database is stored in the	file /var/run/ConsoleKit/data-
       base.  It stores	information about active Seats,	Sessions, and the cur-
       rent SessionLeader.

       The following options are supported:

       --debug		       Enable debug output.

       -h, --help	       Display detailed	usage message.

       --no-daemon	       Avoid starting console-kit-daemon as a  daemon.
			       Useful for debugging.

       --timed-exit	       Exit after 30 seconds.	Useful for debugging.

       See environ(5) for descriptions of environment variables.


	   This	 environment variable corresponds to the Xserver display value
	   associated with the ConsoleKit session.


	   ConsoleKit  provides	 this  environment  variable  to  the  session
	   leader.   The  session leader is expected to	ensure this is set for
	   the session process started.	 It contains a UUID used  to  tie  the
	   processes  to  the session.	This is	used to	support	user switching
	   on displays that support it (currently only graphical  VT  displays
	   on the console).


	   The	XDG_RUNTIME_DIR	 defines the base directory to which user-spe-
	   cific files and objects should be stored.  The  XDG_RUNTIME_DIR  is
	   the	same  for  all sessions	of the same user and will be automati-
	   cally removed once the last session of the user is closed.

       The following environment variables  are	 set  when  console-kit-daemon
       runs  the  run-seat.d scripts.  These values correspond to those	values
       returned	by the ck-list-session(1) utility.


	   The seat ID associated with the session.


	   The user id associated with the session


	   The display device associated with the session.


	   The value of	the display device that	the X11	display	for  the  ses-
	   sion	 is  connected	to.  If	there is no x11-display	set, then this
	   value is undefined.


	   The value of	the X11	DISPLAY	environment variable for this  session
	   if one is present.


	   If  the session is not local, the value is the host name associated
	   with	the session.  If the session is	local, the value is empty.


	   The value is	"TRUE" if the session is active	on the seat  to	 which
	   it is attached, and "FALSE" otherwise.


	   The value is	"TRUE" if the session is local,	and "FALSE" if remote.


	   The	value  is "TRUE" if the	session	was started with ck-seat-tool,
	   and "FALSE" otherwise.

   ConsoleKit Seat Configuration
       ConsoleKit seat	configuration  files  are  located  in	the  /etc/Con-
       soleKit/seats.d	directory.  Each seat configuration file ends with the
       .seat suffix.  ConsoleKit provides a default seat  file	named  00-pri-   Additional	seat  configuration files may be added.	 These
       files are in standard INI format.

       The settings below are in "group/key=default_value"  format,  and  show
       the  default values of the file.	 For example, to spec-
       ify a different "Seat Entry/Name" value,	you would modify the this file
       so it contains these lines:

       [Seat Entry]
       Name=Customized seat name

       The following keys are supported	for configuring	ConsoleKit seats:

       Seat Entry/Version=1.0

	   Version number of the seat file.  This specifies the	version	number
	   of the configuration	file format used.  Currently  only  the	 value
	   "1.0" is supported.

       Seat Entry/Name=Primary seat

	   Name	of the seat.

       Seat Entry/ID=StaticSeat

	   Specifies  the  unique  ID of the seat.  If the value is NULL, then
	   console-kit-daemon will provide a value.  The ID may	 only  contain
	   the ASCII characters	[A-Z][a=z][0-9]_".

       Seat Entry/Hidden=false

	   If  this  value is set to "false", then ConsoleKit will create this
	   seat.  Otherwise, the seat will not be created.

       Seat Entry/Devices

	   This	value is not  currently	 supported.   In  the  future,	it  is
	   planned  that ConsoleKit will provide the ability to	manage how de-
	   vice	permissions are	managed, and this key is a placeholder.

       Seat Entry/Sessions=Local

	   List	of sessions to start on	the seat, separated by the ";" charac-
	   ter.	 Each session must be defined in a ConsoleKit session configu-
	   ration file named /etc/ConsoleKit/sessions.d/sessions.session where
	   sessions is the value of this key.

   ConsoleKit Session Configuration
       ConsoleKit  session  configuration  files  are located in the /etc/Con-
       soleKit/sessions.d directory.  Each  session  configuration  file  ends
       with  the  .session suffix.  Additional seat configuration files	may be
       added.  These files are in standard INI format.

       The settings below are in "group/key" format, so	to specify  the	 "Ses-
       sion Entry/Name"	value, the file	shoulld	contain	these lines:

       [Session	Entry]
       Name=Customized Session

       The following keys are supported	for configuring	ConsoleKit sessions:

       Session Entry/Name

	   Unique name of the session.

       Session Entry/Type

	   Type	of the session

       Session Entry/Description

	   Description of the session.

       Session Entry/DisplayTemplate

	   This	 specifies the display type to be used with the	session.  This
	   corresponds	to  the	 file  /etc/ConsoleKit/displays.d/display_tem-
	   plate.display where display_template	is the value of	this key.


	   The	ConsoleKit display configuration file associated with the "En-
	   try/DisplayTemplate"	key specifies the command to run to launch the
	   display.  This command is defined in	the ConsoleKit display config-
	   uration file	in the key "X11/Exec".	This command can include vari-
	   ables  that	begin with the "$" character, such as "$display".  The
	   values to be	used for these variables can be	defined	in  this  sec-
	   tion.  So if	the session configuration file contains	the value "Lo-
	   cal/display=:0", this will cause the	variable used  when  launching
	   the command to be replaced with the value "0".

   ConsoleKit System Restart and Stop
       console-kit-daemon  provides D-Bus interfaces that will restart or stop
       the system.   When  console-kit-daemon  receives	 a  D-Bus  request  to
       restart the system, it will run the /usr/lib/ConsoleKit/scripts/ck-sys-
       tem-restart script if the user has  privilege  to  do  this  operation.
       When console-kit-daemon receives	a D-Bus	request	to stop	the system, it
       will run	the /usr/lib/ConsoleKit/scripts/ck-system-stop script  if  the
       user has	privilege to do	this operation.

       Example 1: To start the ConsoleKit daemon

       example%	console-kit-daemon

       Example 2: To configure ConsoleKit to start multiple sessions on	a sin-
       gle seat

       To start	two local displays: DISPLAY ":0" on vt7	and  DISPLAY  ":1"  on
       "vt8", edit the file as follows:

       [Seat Entry]
       Name=Primary seat
       Description=start static	displays :0 on vt7 and :1 on vt8

       Then, in	addition to the	original /etc/ConsoleKit/sessions.d/
       sion file, add the following  /etc/ConsoleKit/sessions.d/Local2.session

       [Session	Entry]
       Description=Local Login Screen
