            @KI6UVE - I also have this error on a Innovatek Quadra (can’t find an RPi for sale for love or money).

            Bah. I thought I had something helpful to add. Never mind. It’s not working for me either.

                I know this is an old issue, but I had this happen to me while setting up MM on a Le Potato board.

                Seems like a GPU issue, and you can bypass this by adding this snippet right before you call npm start:

                export ELECTRON_DISABLE_GPU=1

                In my case, I’m using PM2 to manage startup, so my ~/mm.sh file looks like this:

                cd ./MagicMirror
                export ELECTRON_DISABLE_GPU=1
                DISPLAY=:0 npm start
                

                I don’t know the full extent of the issue, but I know that this works and allows me to run MM.

                Hopefully this helps you and anyone else looking for this in the future.
