    After I managed to fix problems with wireless and graphics, I ran into a problem with KDE(nothing too serious).

    I have a laptop and often it is plugged into an external monitor via HDMI. This works without problems.

    Installed system is Debian jessie

    The problem is following. I go to display configuration and I turn off the laptop monitor. It should switch to an external monitor and it does for about 3 secs and than it turns on the laptop monitor back on and reports

    Executable: kded4 Segmentation fault


    Can anyone shed any light on the matter.

    On the display configuration is there a tick box or boxes? Does the external monitor have a tick?

    A last resort would be to remove your .kde folder however this will remove all your kde settings which is not good.

    Is your X configuration settings setup for dual screen?

    Yes I have the monitors to tick. Debian sees them both. It just extends the picture. That is all. And it when I tick one to be turned off it turns off for about 3 secs and gives me an error message stated above.

    To add to this, I was unable to start 3D cube desktop effect. Get a message saying OpenGL is required. Perhaps it is related to the current problem.

    Ok so a stupid solution to a stupid problem. Just set whichever monitor you wish to remain running to be the primary monitor and turn the other one off.
