Ubuntu 16.04 замедляется, CPU, макс. частота является низкой

У меня есть две ОС на моем ноутбуке. Первым является Ubuntu 12.04, и это довольно в порядке, но слишком старое и поврежденное моими неопытными действиями (ручные установки пакета, и т.д.). Вторым является Ubuntu 16.04. Это была новая установка (не, обновляют), и я установил много приложений и библиотек в нем.

Внезапно я заметил, что Ubuntu 16.04 замедляется. Единица становится изменчивой, все приложения, запускаемые медленно. Это происходит однажды некоторое время, особенно после длительного периода работы. (И особенно когда мои друзья, большинство которых является пользователями Windows, работают со мной.)

Переключающийся регулятор не имеет значения.

Pluginn от зарядного устройства и перевключения его назад не имеет значения.

Иногда низкая эффективность появляется в течение нескольких секунд, и затем макс. частота восстанавливает к 2,3 ГГц
