Ich habe da noch ein Problem:
Für die Kinder von Bekannten würde ich gern einen Rechner mit einem 
Mutliseat-Setup versehen, damit die sich nicht mehr beide streiten 
müssen. Da ich noch eine Tastatur und Maus, sowie einen Monitor da 
habe, der sonst weg fliegt wäre so ein Multiseat-Setup nat. ideal.
Hier die Config:
PC mit einer GraKa Nvidia GeForce 8400 GS AGP mit 1x DVI 1x VGA 1x 
SVHS/ TV-out
OS: openSUSE 12.1 (x86_64)
Kernel: 3.4.2-2-desktop
NVidia-Treiber: 295.53
Ich habe als erstes mit "nvidia-settings" eine Dualmonitor- xorg.conf 
und zwei X-screens erzeugt. Also kein TwinView! Die beiden X-Screens 
haben auch funktioniert.
Nachdem also beide X-Screens da waren, habe ich die xorg.conf nach 
folgenden Anleitungen angepasst:

Hier meine xorg.conf:

Warum bricht das ab? Was mache ich falsch?
