Не может настроить двойной экран на Lenovo W530 с Optimus на 14,04

Мне удалось установить nvidia-331-updates драйверы на моей Lenovo W530, и если я запускаю настройки Nvidia, она говорит:

** Message: PRIME: Requires offloading
** Message: PRIME: is it supported? yes

Который является большим. Кроме того, моя установка xrandr кажется очень хорошо:

Содержание xorg.conf - как они должны быть:

    Identifier "layout"
    Screen 0 "nvidia"

Но когда я выполняю настройки Nvidia, это просто клонирует экран и не позволит мне изменить установку. Я хочу распространиться на вторичный экран, когда он включается в порт дисплея.

Править:

Когда я выполняю следующую команду:

# xrandr --output LVDS-1-0 --auto --output DP-0  --mode 1680x1050 --right-of LVDS-1-0 --verbose

это говорит:

crtc 0:    1680x1050   60.0 +1920+0 "DP-0"
crtc 4:    1920x1080   60.0 +0+0 "LVDS-1-0"

и следующее добавляется к Xorg.0.log:

похоже, что это устанавливает DP 0 (внешних) экранов на очень большой дисплей с тем же источником (так клонированный)
