Public bug reported:
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?
