Ubuntu 20.04 становится очень медленным

Моя Ubuntu внезапно становится очень медленной. Когда я перезагружаюсь, она некоторое время работает, а затем снова становится очень медленной.

У меня есть Dell lattitude 7400, подключенный к DisplayLink D6000

Это происходит в основном при подключении док-станции, но не только.

Например, во время индексирования файлов в PHPStorm мой компьютер не работает. Вот htop во время ex htop

Вот несколько журналов, которые я смог найти, когда он начинает работать медленно:
