Ubuntu 17.10 не удается заблокировать экран

Независимо от того, как я пытаюсь заблокировать свой экран (Super + L, Пункт меню или Тайм-аут), экран пытается заблокировать, но на секунду останавливается и возобновляет мой текущий сеанс работы с GNOME. Если после этого я попытаюсь снова, мой сеанс останавливается и должен быть перезапущен.

Если мой компьютер останется на обычном экране входа в систему без входа пользователя, он будет соблюдать настройки электропитания и выключит экран через 10 минут.

Ниже приведен дамп моего системного журнала во время сбоя.
