Дистрибутив Debian Etch. Хочется поднять несколько рабочих мест на одном системном блоке.
Пошарил в инете -- нашел примерные конфиги для Xorg, gdm. Состряпал свои (только у меня kdm)
Пока начинаю для 2-х рабочих мест.

================= xorg.conf ====================

И вот в чем проблема...
Если набрать в консоли# "X -layout X1", то запускаются иксы на первом рабочем месте (серый  экран и курсор мыши), если "X -layout X2" тоже самое запускается на втором рабочем месте. Но ни как не получается заставить KDM выдать loginscreen на оба рабочих места, что бы ни делал запускается только на первом. Возможно нужно еще какие-то конфиги крутить?
