Starting from Kubuntu 14.04, when I open systemsettings > Monitor > Display Configuration, I see, additionally to my built-in monitor on my laptop (Samsung RF511 - monitor displayed as "Seiko Epson Corporation"...) an additional screen named "VGA-1-2" - which is enabled.
This "monitor" is detected despite it does not exist. I discovered that because some apps I started did not appear on screen, and the mouse cursor somehow "vanished" behind the right screen edge, until I found out that they were placed on that second screen - I could "drag" the windows per Alt+LeftClick blindly from somewhere in the right to my actual monitor.

a screnshot of systemsettings is attached.
Then I attached a *real* second monitor to my laptop - systemsettings detects it correctly and expands the screen - but now tells me that I have *three* monitors...

This is really a regression to 13.10, and as the monitor is detected
*and* enabled by default, it is not really good to work with, as windows
are "vanishing" somwehere.


I can reproduce this behaviour with a Kubuntu live ISO on my system. So it is NOT my misconfiguration ;-)
I before had Kubuntu 13.10 with KDE 4.12.5, running well without this bug.
I am using a laptop with optimus graphics: intel/nvidia card, corresponding lspci lines:

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 3D controller: NVIDIA Corporation GF108M [GeForce GT 540M] (rev a1)

What else (log files etc) do you need from me to help resolve this bug?
