Несколько мониторов с оконным менеджером i3

Я только начал использовать i3 (версия 4.17.1) и не могу понять, как заставить его работать с двумя мониторами. Я использую Ubuntu 20.04, и когда я вхожу в gnome, он использует их обе. Мое исследование показало, что мне нужно выполнить следующую команду. HDMI-0 - мой основной монитор (тот, который работает), а DVI-1-0 - мой второй монитор (не работает).

$ xrandr --output DVI-1-0 --auto --right-of HDMI-0

Насколько я могу судить, это ничего не дало. Я запускал xrandr как в gnome, так и в i3, чтобы, надеюсь, помочь мне в устранении неполадок. Их содержимое вместе с моим файлом конфигурации i3 ниже. Я вижу различия, но у меня недостаточно опыта, чтобы знать, что с ними делать.
