IMAC со вторым экраном Apple на Ubuntu 18.04

После 2 недель тестирования и не найдя решения, я решила обратиться за помощью. Я подведу итог моей ситуации.

imac 27" (from 2014) + Thunderbolt display 27" + Linux

Он работал отлично, когда я использовал Ubuntu 14.04 LTS в прошлом, но после некоторого обновления второй монитор не работал.

Итак, я решил почистить свой компьютер и установил свежую Ubuntu 18.04 LTS.

Во время установки с работающим USB он работал, но после перезапуска выключен.

Мне действительно нужен второй экран, поэтому я ценю любую помощь экспертов.

Некоторые примечания:

1. дисплей подключен с помощью кабеля Thunderbolt ( как этот ), а динамики и USB работают. Только экран выключен.

2. Я пытался использовать драйверы: nvidia-driver-390, nvidia-driver-340 и xserver-xorg-video-nouveau.

3. У меня все еще есть обновленный раздел с MacOS Mavericks, и там все хорошо работает.
