Nvidia optimus - Как настроить xserver на двух экранах?

У меня ноутбук с технологией nvidia optimus. Я установил bumblebee, и все, кажется, работает нормально. Проблема в том, что когда я подключил второй монитор к ноутбуку после входа в систему, он работает хорошо, но когда я запускаю ноутбук с подключенным монитором, Xserver не может запуститься. Как настроить xserver, чтобы он заработал?

Вот моя конфигурация оборудования:

$ xrandr -q
Screen 0: minimum 320 x 200, current 3040 x 900, maximum 8192 x 8192
LVDS1 connected 1600x900+1440+0 (normal left inverted right x axis y axis) 382mm x 214mm

Мой xorg.conf почти пуст:

Section "Device"
    Identifier  "Default Device"
    Option  "NoLogo"    "True"
EndSection

Как настроить Xorg, чтобы он работал?
