Размер экрана и разрешение конфликта

Я новичок в Linux и могу немного помочь с проблемой.

Я пытаюсь добиться очень конкретного разрешения и размера экрана (720x480 @ 59,94) для моей безголовой настольной коробки Ubuntu 12.04.2-64 с картой nVidia GeForce 8400 GS.

Машина используется главным образом для SSH и GUI (удаленно). Ограниченные драйверы не работают для моей ситуации. Я создал и попытался изменить файл xorg.conf в соответствии с пользователем, но я не достиг желаемого результата. Отредактированный файл xorg.conf отображает рабочий стол в желаемом масштабе или разрешении, но на экране всегда отображается 1280x768. Когда я пытаюсь добавить DisplaySize 720 480 в раздел «Монитор», он разрывает файл и не создает рабочий стол.

Вот файл xorg.conf:
