помогите настроить Xinerama на intel

Имеется ноут с видюхой intel 945GM, и внешний моник Samsung 710N, xorg-server-1.6.2, дрова xf86-video-intel-2.7.1. Находил в инете какие-то разные маны, которые по большей части совпадают, но так ничего и не добился. xorg.conf довел до вот такого вида:

Если раскомментировать любую из строк #Option "Xinerama" "True", то иксы не грузятся, вот лог, а в текущем виде, на втором монике клон левого верхнего угла дисплея ноута размером 720х400 или 640х480.
DE - xfce, и в некоторых настройках показывает наличие двух моников, но в настройках дисплея показывает только один дисплей с выбором вышеперечисленных разрешений на выбор, то есть позволяет настраивать внешний моник.
