Black Desktop after installing PIR-Sensor

  • Hello,

    unfortunately I have a problem with my PIR-Sensor.
    I followed the instructions of MagicMirrorCentral (
    Now the PIR sensor also works. But after I installed that and restarted the Raspi, my desktop is black. But only the desktop. The application, MagicMirror, is displayed. When I minimize MM with Ctrl + M, I only see a black desktop. The mouse pointer is displayed and can be moved. But I can not click on anything.

    Of course I already tried the option with “vcgencmd display_power 1”. Unfortunately with the same result.
    I would really appreciate, if you could help me.

    Thank you in advance.
