Порт HDMI и порт VGA не распознаются в Fedora 27

В моем новом ноутбуке есть видеокарта NVIDIA (не знаю, какая именно). Я недавно установил Fedora 27. Однако я не могу заставить мой порт HDMI или VGA работать или даже быть распознанным. Я пробовал следовать инструкциям в https://www.if-not-true-then-false.com/2015/fedora-nvidia-guide/ и https://fedoraproject.org/wiki/Bumblebee (а также некоторых других), но пока безуспешно.

Вот некоторые результаты различных команд для контекста:
