Application not starting when OpenGL is enabled

richland007

@klinge I think the appilcationstarts but on server mode only at least thats what it was doing on my case…go on a different computers webbrowser and type your mirrors RaspberryPi IP address and :8080 as the port number http://raspberrypiIP:8080 and see what you get.

I did not find a solution to it i just took OpenGL out of the equation and it works fine

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

Klinge

Thank you for your advice. I will try it on Monday

Klinge

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.

Anthony

@sean Thank you for your fast reply. I’ll give it a try as soon as I get home and see how it goes.

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

Anthony

@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?

Anthony

@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.

@anthony no it’s not that bad it depends what modules you have on it to how much it’s working in the background mine is between.90 and 1.5 cpu usage once everything has loaded, ram is a different story and goes down over time now until it crashes the Pi that’s why I’ve got a Cron Job to reboot the Magic Mirror software every 12hours for me, which has seen it go for days without issues.

Anthony

@dazza120 OK then. I’ll give it a try when I get home and see hoe it goes. Thank you for your reply.

@anthony you will need a heat sink on the Pi my temps with Pi with screen Off is about 47c bare in mind it’s the UK and about 20c in my house at the mo so summertime I expect to see about 60c still well within spec, but now I’ve got a fan on it that only turns on when the monitor is in use which saw temps go to 33c so not bad, hope this helps

Anthony

@dazza120 I already have heat sinks on all 3 chips of my rpi and a fan as well. I bought it like this in a case. I don’t know about temperatures because I haven’t monitor them yet but I hope you are right and not have any overheating problem. Thank you again.

@anthony mines been running for 5days because I was trying to get GL running to see what it was like but so many problems with that on the Pi, anyway yep that’s the readings I just took them today, I have MMM-SystemStats you may want to look at it for the Pi

Anthony

@dazza120 I will install it as soon as I get home and solve another problem with black screen I have right now (too many reasons for black screen). Thank you so much for your help.

dazza120

@anthony yeah found GL caused black screen and running out of ram that’s why I have a Cron Job running every 12hours as after 24hours it would go dark, hence Cron job every 12hours

rts58

@anthony I am also noob. But, I installed pm2 and it allowed me to run OpenGL. I think it keeps electron and other running processes from using up all memory and will help.

dazza120

@rts58 as mentioned GL causes all sorts of other issues for the Pi really not advisable
