Неустранимая ошибка сервера: (EE) не найдено ни одного экрана (EE) в любом tty

Я хочу создать «виртуальный дисплей», чтобы использовать другое разрешение экрана.

Я открыл любой tty от tty2 до tty6 и попробовал это:

sudo startx -- :1

... но всегда получаю:

xauth: (stdin):2:  unknown command "f86ae7809cf17138ea28ef7a7e32d2bb"

Я не знаю, как мне действовать

Кстати, у меня есть графика Nvidia и Intel, и я использую драйверы nvidia (проприетарные) и i915 соответственно
