Зависает и не выключается комп

Выключал коммандой systemctl halt
Много ждал и выключил ноут долгим зажатием кнопки включения.

И ещё, как избавиться от ошибок NM? dbus запущен
fuelen
Выключал коммандой systemctl halt
Может лучше
$ systemctl poweroff
?
Да пребудет с нами Сила...!

уже не раз обсуждалось и сам влетал
Ошибки не исчезают с опытом - они просто умнеют
Ну с остановкой системы разобрались.

Нечто подобное было не так давно. Не уверен, но:
systemctl status ModemManager.service
?

P.S. Хотя вряд ли. Тогда сыпало именно сообщениями о незапущенном ModemManager.service. Но чем черт не шутит...
Спасибо, всё помогло :)
