I could setup xorg.conf to force things. Buts that is not how the
modern Linux desktop is supposed to work right?

I login and my preferences get used. Expect that is not working.

I assumed that KDE will read my display config and do the xrandr
stuff that is necessary to setup my two displays.

KDE can clearly setup my displays as I do that every time I login
with the System Settings app.

When I click the apply button does KDE save my display settings
to disk?

When KDE starts up is it expected to read the settings back in?
