        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

              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.
