So I found the old thread here:
http://lists.fedoraproject.org/pipermail/kde/2011-April/009337.html
and the related bug
https://bugs.kde.org/show_bug.cgi?id=183143

But I still can't figure out how to revert the settings so that I can use the 
laptop by itself. Now without first attaching an external display, windows 
always shows up somewhere off screen.
