[Решено] Ошибка consolekit

Сделал, по совету, добавил в ~/.xinitrc следующее:

exec startxfce4 --with-ck-launch

Теперь стартую иксы, смотрю сессии командой ck-list-sessions, их теперь две:

Session1:

	unix-user = '1000'

	realname = '(null)'

	seat = 'Seat1'

	session-type = 'unspecified'

	session-class = 'user'

	session-state = 'online'

	active = FALSE

	x11-display = ''

	x11-display-device = ''

	display-device = '/dev/tty1'

	remote-host-name = ''

	is-local = TRUE

	on-since = '2017-07-25T05:19:37.705383Z'

	login-session-id = '1'

	XDG_RUNTIME_DIR = '/var/run/user/1000'

	VTNr = '1'

Session2:

	unix-user = '1000'

	realname = '(null)'

	seat = 'Seat1'

	session-type = 'unspecified'

	session-class = 'user'

	session-state = 'active'

	active = TRUE

	x11-display = ':0'

	x11-display-device = '/dev/tty7'

	display-device = '/dev/tty1'

	remote-host-name = ''

	is-local = TRUE

	on-since = '2017-07-25T05:19:49.933669Z'

	login-session-id = '1'

	XDG_RUNTIME_DIR = '/var/run/user/1000'

	VTNr = '7'

Иксы запускаю через startx, да. Никакого displaymanager'а нет.

If ConsoleKit is not working (ck-list-sessions command showing active = FALSE), you should start your window manager using the bash_profile method: Start X at login#bash profile.

Как это сделать, не подскажете?
До сих пор проблему не решил, просто не знаю с чего начать. В consolekit совсем не разбираюсь. Маны понять не могу, там не указывается моя проблема. Уж простите мою тупость.
Если добавить в .xinitrc такую строку

exec ck-launch-session dbus-launch --sh-syntax --exit-with-session xfce4

то иксы не запускаются (из-за --exit-with-session вероятно).

Кнопки Reboot, Shutdown активны.
