Настройка мультистанции (Dual Seat) на паре видеокарт.

В этой статье рассказывается как настроить Dual Seat на паре видеокарт (встроенная+внешняя).
Если у вас встроенная видеокарта не настраиваемо отключается при наличии внешней, или есть только внешняя
двухголовая видеокарта, то вам сюда /AltLinux/Dokumentacija/Multistation.

Оборудование

мама Gigabyte GA-M55plus-S3G со встроенной nvidia 6150LE (Низкий поклон Саше led@ за совет)
внешняя nvidia 8400GS
2 монитора
2 мыши Logitech (ps/2+usb)
ps/2 клавиатура
usb клавиатура A4tech-KIP800

Софт

архитектура x86_64
xorg-x11-server-1.4.0.90-alt8
xorg-x11-drv-evdev-1.2.0-alt3
пакеты установлены в branch 4.0 из Сизифа 200801xx.
пришлось еще дополнительно обновить ряд пакетов и обновить все пакеты шрифтов (важно).
(в бранче 4.0 xorg-x11-drv-evdev сломан для клавиатур, да и xorg-x11-server лучше брать 1.4.0).

Грабли

есть.
1) evdev не нашел устройства через
Option “Name” “string”
Option “Phys” “string”
пришлось использовать
Option “Device” “string”
хотя use of this option is strongly discouraged.

2) Нельзя инициализировать 2 X сервера сразу.
