Обновление apt-get не удалось подключиться к

С включенным Optimus и обнаружением ОС в BIOS, у меня есть 2 внешних монитора, подключенных к DVI (док-станция - карта Nvidia) и ЖК-дисплей для ноутбука (плата Intel). Я также получил карту VGA (Intel) на стыковке, но не смог ее использовать в качестве клона ЖК-дисплея для ноутбука.

Вот моя конфигурация xorg с включенным Xinerama: [!d1 ]
