Почему Xorg отказывается генерировать файл xorg.conf для меня?

У меня есть монитор DisplayLink, который я пытаюсь добавить на рабочий стол Ubuntu. После подключения к нему экран становится полностью зеленым, и я понимаю, что модуль ядра DisplayLink установлен и может взаимодействовать с устройством.

Добавление монитора к моему xorg.conf не должно быть слишком сложным кроме есть no /etc/X11/xorg.conf. По-видимому, мне нужно сгенерировать одно - так вот что я пытался сделать с помощью следующей команды:

Xorg -configure

Однако это, похоже, терпит неудачу. Вот результат команды:
