Недавно я получил 2-ую видеокарту для добавления 3-го монитора, но у меня были проблемы с отображением 3-го монитора. Конфигурации сервера nvidia x распознают 3-й монитор и 2-ю графическую карту. Когда я пытаюсь включить третий монитор через настройки nvidia и перезагружаюсь, он просто возвращается без изменений. Я открываю настройки nvidia и 3-й монитор снова отключен. Я попытался отредактировать файл xorg.conf вручную, чтобы попытаться добавить третий экран, но пока мне не повезло.
Я использую Linux Mint с 2 графическими картами Geforce 750ti. Насколько я понимаю, они не соответствуют SLI, но используют настройку MultiGPU, которую я включил в файл conf.
Вот мой файл конфигурации, расположенный в: /etc/X11/xorg.conf
Я попытался добавить Screen2, но это не имело никакого эффекта. Любая помощь в правильном направлении была бы отличной!
