I am happy to report that I got my dual monitors working.  I don't know
what exactly did it, but here is what I did.

I suspected that the laptop display was not working due to a power
management issue, ie the screen was dimmed too dim to view.   I
suspected this because I have seen this happen after the laptop comes
back from a suspend event. 

So... I went into KDEStart->Settings->System Settings -> Advanced ->
Power Management-> Edit Profiles -> Screen.  

I then disabled "Enable display power management" on each of the
profiles, saving them as I went.

The I logged out of my KDE session and logged back in.   The laptop
monitor was then functional. 

I'm not certain that power management was the issue, but this sequence
of changes fixed my issue.
