Монитор больше не работает после обновления видеокарты

Я недавно обновил свою видеокарту с GTX 760 до GTX 1070. Когда я запускал Linux, у меня была ошибка в lightdm . Я решил, что это стандарт, и мне просто нужно было установить новые драйверы, поэтому я нажал CTRL - ALT - F2 и выполнил # apt-get обновите nvidia * . Эта команда зависала несколько раз, и мне нужно было запустить ее вместе с ^ C. Излишне говорить, что это не решило проблему.

Я попробовал несколько других решений, в том числе закомментировал блок «Nvidia» в файле Xorg.conf:

Я надеялся, что это заставит Xorg перестать пытаться использовать драйверы Nvidia и вместо этого будет использовать те, которые уже установлены. ядро. Вместо этого, когда я запустил service lightdm start , мой монитор стал черным и выдал сообщение «Не поддерживается».

Я не могу выбраться из этого: я попытался остановить службу lightdm, перезагрузить компьютер, запустить Xorg: 1 -configure , переустановить драйверы nvidia и переустановить свой DE.

В настоящее время я подключен к своему компьютеру через SSH, поэтому я не могу делать ничего, что потребовало бы изменения сетевых настроек.

Вот еще несколько журналов, которые могут оказаться полезными, а могут и не пригодиться:
