Digging somewhat more, it appears that none of the seats allow to
activate sessions (CanActivateSession) except one. The strange thing is
that that one seat doesn't contain any session. The other strange thing
is that none of the seats are associated with any device (GetDevices).
Anyway, here is what a slightly more complete version of the script above tells
me in a graphical session:
-----------------------------------------------------------------------------
# Seat '/org/freedesktop/ConsoleKit/Seat2':
can_activate: 1
devices: dbus.Array([], signature=dbus.Signature('(ss)'))
active_session: None
# Seat '/org/freedesktop/ConsoleKit/Seat14':
can_activate: 0
devices: dbus.Array([], signature=dbus.Signature('(ss)'))
active_session: None
# Session '/org/freedesktop/ConsoleKit/Session12':
Traceback (most recent call last):
File "./x.py", line 25, in <module>

message, timeout)
DBusException: org.freedesktop.DBus.GLib.UnmappedError.CkSeatError.Code0:
Activation is not supported for this kind of seat
-----------------------------------------------------------------------------
One last strange thing... When I log out from my graphical session and type
ck-list-sessions in a console terminal, I can notice that gdm has a session of
its own, but that session is not active either and, in fact, none of the
sessions is marked as 'active', even my console session:
-----------------------------------------------------------------------------
Session16:
unix-user = '1000'
realname = 'david'
seat = 'Seat18'
session-type = ''
active = FALSE
x11-display = ''
x11-display-device = ''
display-device = '/dev/tty1'
remote-host-name = ''
is-local = TRUE
on-since = '2009-11-14T15:38:16.887770Z'
login-session-id = '4294967295'
Session13:
unix-user = '105'
realname = 'Gnome Display Manager'
seat = 'Seat15'
session-type = 'LoginWindow'
active = FALSE
x11-display = ':0'
x11-display-device = '/dev/tty7'
display-device = ''
remote-host-name = ''
is-local = TRUE
on-since = '2009-11-14T15:37:34.131625Z'
login-session-id = '4294967295'
-----------------------------------------------------------------------------
Would anybody have any clue for that ?
