      The version is “version”: “2.27.0”,

      The config for the background is

      
      {
        module: 'MMM-BackgroundSlideshow',
        position: 'fullscreen_below',
        config: {
         imagePaths: ['modules/MMM-BackgroundSlideshow/fotos/'],
         randomizeImageOrder: true,
         slideshowSpeed: 60000,
         backgroundAnimationEnabled: false,
         gradient: [ "rgba(0, 0, 0, 0.5) 0%", "rgba(0, 0, 0, 0.15) 40%", "rgba(0, 0, 0, 0.15) 80%", "rgba(0, 0, 0, 0.5) 100%" ],
         horizontalGradient: [ "rgba(0, 0, 0, 0.5) 0%", "rgba(0, 0, 0, 0.15) 40%", "rgba(0, 0, 0, 0.15) 80%", "rgba(0, 0, 0, 0.5) 100%" ],
         gradientDirection: 'both',
          },
      },     
      
      

      Thanks for your help

        @Dotmatrix812 ok, 2.27 turns off use of the gpu by default

        do this, open a terminal window

        pm2 stop all
        cd ~/MagicMirror 
        export ELECTRON_ENABLE_GPU=1
        npm start
        

        and see if that message continues

        you will have to minimize MagicMirror to get back to the terminal window
        ctrl-m
        should work

            Seems so.

            Strange that the time stamp is so different …

              No. Monitor is connected to the raspberry. Or could this happen when the monitor gets switched off via the MMM-PIR module ?

              Sorry that my answers take so long. But I still need 3 reputations as new user.

                    Time with the grandson is very important 👍

                    I will check if I can find out if the errors appear after the monitor gets switched off.

                      I have MM v2.27.0 on a Pi 3 running bookworm with a monitor attached and I get the same 3 lines in my npm logs.

                      The Pi is using a PIR to monitor presence and turn off the screen after a fixed period of inactivity from the PIR. The screen is turned off by calling a shell to execute xrandr.

                      I can reproduce the error by issuing the command:

                      DISPLAY=:0.0 xrandr --output HDMI-1 --off
                      

                      while the screen is on. No errors occur if I use the same command and the screen is already off.

                      Hope this helps.

                        @tinkertailorgeek thanks… so the code managing the screen doesn’t like having the hdmi channel chopped out from under it…
                        I assume the errors go away when the hdmi port is turned back on
