5. Problem - Zwei Monitore konfigurieren

Ich habe hier einen 18" und einen 15" (siehe unten) TFT stehen. Bisher gibt meine Grafikkarte aber nur ein Bild auf dem 18"er aus. Ich würde gerne beide Monitore benutzen können wie ich das schon unter Windows mache. Beide Monitore sollen unabhängig voneinander arbeiten. Meißtens habe ich auf dem großen TFT einen Browser offen, während der kleine Monitor mein E-Mail Programm im Vollbild darstellt.
Das hier ist meine aktuelle xorg.conf, wenn jemand den Nerv hat auf Grund dieser Konfiguration eine neue xorg.conf zu erstellen, die meinen LG L1515S anspricht.
Die Specs habe ich hier: http://www.techtree.com/India/Reviews/LG_L1515S_LCD/551-69054-630.html
Ich würde mich freuen, wenn jemand die neue xorg.conf als Kommentar posten würde.
