            Bug ID: 346738
           Summary: Connecting  TV screen fails ( all screens get (partly)
                    blank )
           Product: KScreen
           Version: 5.2.95
          Platform: Archlinux Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: kded
          Assignee: dvratil@kde.org
          Reporter: dbacc@posteo.de

I have a system setup with currently 3 displays on a Nvdia Optimus system, i.e.
I fire up some virtual displays at start of sddm in order to be able to connect
my monitors (intel-virtual-output).
At this stage I also pass some xrandr command, that fits my needs.

Now, if I plug in my TV as a forth screen, things break down immediately after
login or right after plugging in the TV - depending on which occurs first.
That means 3 of the screens are getting dark, and my main screen (laptop LVDS1
) shows half of some of the desktops that were there before.

Reproducible: Always

Steps to Reproduce:
1. Disconnect TV
2. Start KDE
3. Connect TV

Actual Results:  
Screens turn (partially) black

Expected Results:  
4 different desktops showing up

Here is a log file created after plugging in the TV:

And here the output of kscreen-console bug:
