      Try this
      npm start — —disable-gpu
      — is - -(dash twice.) I’m not sure disable or disabled. Try both.

          I tried both. …disable-gpu unfortunately does not not bring any improvement. So I took OpenGL out of the equation and it works.

            I have the same problem. When OpenGL is enabled the application freezes at launching and I must unplug my pi from power and plug it back. I even tried to update electron to a newer version but I got another error there so I end up disabling OpenGL again.

              Just use serveronly (node serveronly) instead npm start.

                  Are you using pm2? I was having same issue, and was able to resolve by following pm2 setup process.

                    OpenGL causes nothing but problems on the Pi I had to go back to legacy, full GL caused locked up the Pi causing black screen from the start of the MM, Fake GL caused MMM-voice not to work, so had to go back to legacy and all problems above gone

                      @rts58 No I am using npm to start the mirror. Also I am completely noob about coding and I am trying through googling and the forum for answers. So if I install pm2 will work when OpenGL is enabled?

                        @dazza120 Same thing here but I’ve read that the latest versions of electron use an extreme amount of CPU power when no Open GL driver is loaded. This will result in an overheating Raspberry Pi. That’s why I am trying to enable it.
