http://forums.opensuse.org – This thread is based on my experience with KDE-4.3.x in driving an external projector with a cloned output of a laptop display.

With KDE-4.3.2 running, I plugged in the external cable from the projector. There was no response, as expected. I then typed "xrandr -q" and immediately I obtained this popup and I selected "configure): The CRT1(Connected) size was "disabled", and I then selected "1440x900 (Auto)".
