I bet you do - kde has some real
bastard issues with multi-monitor I've been finding.
If you're on 14.04, you're mostly hozed - they didn't fix kde
remembering display setups until plasma 5.x. This alone drove me
into the 16.04 adventure with plasma 5.
I was actually just digging through their bugs when I saw this,
there are a ton of issues with current releases in ubuntu and
everything really, plasma 5.5 to current 5.7.1 all seem affected.
Now with 16.04 and plasma 5.5 on here, it remembers where my
monitors go, but about everything else is broken. Someone decided
to remove a particular null monitor feature in kde that destroys
it's ability cope with displays disappearing as things toggle
around with xrandr functions, causing kwin, plasma, and about
every other aspect of kde to freak out. Now they seem to be
trying to put it back, but so far everyone is still broken in
5.7.1.
Sadly most of these issues relate I found in the kde trackers
around these issues are a year or more old, and they don't seem
great about actually fixing old/persistent problems. Seems they
just keep making new features without fixing the old ones, like
monitor placement in plasma 4.
Easy for them to say "just upgrade to 5", but not when it requires
a distro release upgrade, and then finding it is even more broken
is slightly infuriating.

Odd KDE multi-monitor behavior with Optimus.
I have it working, and for the most part its
great. But what i am getting now is some really strange
behavior with Nvidia and Intel graphics.
Everything comes up and renders beautifully. I
can even arrange them and move things back and forth. But
anytime i move to the Intel controlled monitor (in this case
laptop display) it slides the Nvidia controlled screens off to
the side (or up if i set it below).
I have no idea where this behavior is
controlled from and my google searching is coming up with
nothing like it before. And while technically functional its
kind of weird and not very helpful behavior.
