Bluetooth включается, но не подключается к устройствам Ubuntu 18.04

У меня возникли проблемы с интерфейсом Bluetooth на ноутбуке Asus.

Bluetooth, кажется, включен, но он не может подключить устройства. Я попытался обновить ядро ​​с 4.15 до 4.17, но ничего не изменилось.

Когда я набираю sudo service bluetooth status, это печатается на терминале:

giu 16 12:38:43  bluetoothd[1052]: Bluetooth daemon 5.48
giu 16 12:38:43  bluetoothd[1052]: Starting SDP server

giu 16 15:37:48 bluetoothd[1052]: Can't get HIDP connection info
giu 16 15:38:29 bluetoothd[1052]: connect error: Connection refused (111)

Я читал о других пользователях с той же проблемой, но их решения не работают на моем ПК.

Есть предложения?
