Good morning,
I have two desks into two separate X sessions. The second is connected to a TV where I run XBMC. For a few days it does not show the decoration of windows, however on the screen 1 is displayed perfectly. How can this be?

Please provide the output of "echo $DISPLAY" from a terminal on each screen.
Also, are you able to drag windows between the two screens?

Hello,
Screen output 0 is:
echo $ DISPLAY
: 0.0

output display 1 is:
echo $ DISPLAY
: 0.1

I can not drag windows between the two screens.

The command qdbus org.kde.kwin /KWin supportInformation
shows the following:

Being unable to shift windows to the other screen is a key indicator here they are totally separate. To my knowledge, you will probably need to run a second instance of KWin, or change the configuration you use for your screens to allow applications to cross between them. I'll leave a final conclusion on what is needed to the KWin developers though.

https://bugs.kde.org/show_bug.cgi?id=256242

See the latter posts.

Reason why it does not autostart is fixed with http://git.reviewboard.kde.org/r/112579/

OK. Thank you very much for the info. I will configure my x server with TwinView.
