Application not starting when OpenGL is enabled

@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
-
@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
-
@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.
-
@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
-
@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.
-
@rts58 as mentioned GL causes all sorts of other issues for the Pi really not advisable
-
@dazza120 I was also running OpenGL because mostly of this thread. I was/am concerned about temps, my pi is stuck in a wall and I’m running modules for background images, weather, nests, calendar and newsfeeds. When I first tried the fake and full I was having startup problems so started using pm2 which fixed them. I just now performed a very unscientific comparison. I ran under each driver and compared the average 15 minute processor usage (after 30 minutes).
Full - .62
Fake - .45
Orig - .36
I wasn’t smart enough to pay attention to the other stats :frowning_face: . But for now I am going to follow your recommendation and drop OpenGL. Thanks. -
@rts58 get MMM-SystemStats works well for the Pi and you can see memory,cpu and temp readings very handy when your running a Pi, if it ever happens that it goes black screen from days of use you will need to set a Cron job that refreshes the MM so memory starts over again hope that helps

@anthony - Just FYI: PM2 is a process manager. It’s purpose is to make sure that the Magic Mirror process is always running and to start it automatically when you Pi boots. That’s all. It won’t help nor hinder your mirror’s performance.
When your Pi starts to overheat, you’ll see a thermometer icon in the upper right corner of your mirror.
