У меня есть Acer Aspire E5-551G. Wi-Fi работает нормально, но Bluetooth не работает ?. Я уже пробовал несколько способов решить эту проблему, но ничего не сработало для меня. Вот некоторые результаты, которые требовались различными подходами к решению моей проблемы.

После перезагрузки Bluetooth больше не работал. Я узнал, что мне пришлось добавить btusb в /etc/modules. Но когда я сейчас перезагружаюсь, у меня есть Bluetooth-записи в моей панели управления Gnome (эта вещь в правом верхнем углу), которая не будет работать и перенаправит меня только на мои настройки сети. После включения Bluetooth в моих настройках появляется вторая запись Bluetooth.
