intel + dual screen

Исходные данные:
Ноутбук Acer Aspire 3682

#lspci
00:02.0 VGA compatible controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)
00:02.1 Display controller: Intel Corporation Mobile 945GM/GMS, 943/940GML Express Integrated Graphics Controller (rev 03)

Что хочу:
основные иксы с выводом на экран ноутбука как Screen 0 (DISPLAY=0)
screеn 1 (DISPLAY=1) с выводом на VGA-выход ноута (внешний монитор). Там никаких оконных менеджеров, а просто при необходимости DISPLAY=1 mplayer test.avi (к примеру).

После старта иксов на VGA выходе получаю дублирование Screen0 с экрана ноутбука.
В логе что примечательно:
(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found
Но такая секция присутствует (см. xorg.conf)
Версии пакетов:

x11-drivers/xf86-video-i810-2.1.1
x11-base/xorg-server-1.3.0.0-r6

Надеюсь на помощь, ибо над проблемой бьюсь уже долго.
