From my understanding, too many other non-kde things including many things in Unity rely on specific versions of QT, so the Kubuntu team uses the version of QT included with the system, so I wouldn't have gotten upgraded with the new version of KDE.

Perhaps you can find a pattern that you can turn them back on in that will give you the proper setup.  In theory it should always put them back in the proper order.  My guess would be that they are checking their database of monitors incorrectly so that monitor A + monitor B is not looked up the same way as monitor B + Monitor A.

That's why I went with a $35 HDMI splitter that sounded like it would do the same thing. I'll have to remember to let you know if it works when I finally get it hooked up.
