    @09succotash Umpf…the last thing that comes to my mind…disconnect the PIR-Sensor from GPIO. Maybe it is not connected to the right pins, which may cause that strange behaviour.

    Do you have the MM-software installed? If so, then copy the whole MagicMirror directory to a save place and reinstall Raspbian from scratch. It’s probably the fastest and easiest solution after all, if nothing else is installed on the RPi.

    Maybe someone else here in the forum can help? Guys?

        @Fozi I can’t reinstall Raspbian because this is for a science fair project, due in two weeks, and I put too much work into it for me to be able to finish on time if I reinstall. There has to be a way to get my desktop back without reinstalling.

          @09succotash As said, copy the whole MM-folder, eg. via scp to another PC and then reinstall Raspbian.
          I’m sorry that I can’t provide a more satisfying solution:disappointed_face:

                  @sdetweil I cannot ssh into it. I am able to access the terminal though. MM is running on pm2, I just setup an autostart script for it. I don’t think MM is causing the issue, because the issue started just when I was setting up the PIR sensor.

                    @09succotash but it can’t hurt to stop it…

                    if you can get to terminal, then its not a desktop problem…

                      @sdetweil I could only get to terminal, by right clicking somewhere on the screen. I tried stopping MM using pm2, didn’t have any effect.
