Bug ID: 501346
Summary: KCM reports impossible and wrong configurations,

setups

Screenshot of the KCM in an inconsistent state
SUMMARY
With multi-monitor setups, the KCM reports patently absurd screen
configurations that make no sense whatsoever. As an example, see the
screenshot: there are three monitors (one is the laptop's), and one is enabled
but not correctly displayed so it can't be dragged nor interacted with. The KCM
does not enable the "apply" button if I change the mirroring (so it stays
disabled whether I make it mirror the laptop's screen, or whether I don't). The
whole thing is inconsistent to the point I cannot understand what is going on.
I suspect this might be related to bug 466297, as this situation arises when
the laptop screen is disabled (e.g. if I close the lid, or if the system boots
with the lid closed).
In any case, this makes it extremely frustrating to use Plasma as it requires
10+ minutes of troubleshooting every time.
STEPS TO REPRODUCE
1. Use a laptop with a multi-screen setup
2. (maybe) mirror your laptop's screen to another monitor
OBSERVED RESULT
The KCM reports wrong, inconsistent and/or impossible configurations, and
behaves erratically.
EXPECTED RESULT
The KCM reports the actual state and allows you to modify it.
