Just found your guide: https://forum.magicmirror.builders/topic/5274/how-to-manually-install-mm-on-your-pi-for-absolute-beginners

Going at it now and see if it works - thanks for the patience and writing that guide!

You’re welcome, sir. :-)

Got my mirror working again. Had to go over the opengl drivers again and using the fake kms driver did the trick. However one problem remains, i had to also disable the MMM-Pir-Sensor module because that was messing with the system. But also my custom.css is not being used atm, and i cant figure out why its not grabbing it.

Anyone else struggling with using MMM-Pir-Sensor after the new update?

Yes, I am having the same black screen. I have to disable PIR to be able to use MM at all. I also noted that after I installed PIR I could no longer SSH into the Pi from my desktop computer, whereas I could from my mobile phone. Anyway, the black screen is the main concern right now. I’ll post if I discover anything helpful.

Not sure if I’m having the same issue, stupidly updated electron as npm was claiming 1.7.13 had a critical vulnerability (after installing MMM-voice) Then got the backscreen issue. rolled back electron to 1.7.13 & the issue persists.

Node v9.11.1
npm 6.1.0

Thought I’d uploaded the log file but not sure if others can see it. That snippet below is the first error after ALL_MODULES_STARTED

Any pointers as to how to get it working again? It was working perfectly before MMM-voice & buggering around with electron.
Tried a fresh install with the same result :(

I’m also having the black screen of death. I tried both overlay options, and I tried commenting it out alltogether. I also ran the 2.4.1 update, but still getting black screen. Runs normally with the new update though when I comment out the PIR module in the config.js file.

@shane1234 if u have the PIR module loaded, and do ctrl-shift-i (lower case letter i), it will open the debug env, and then select the console tab… do you see any errors?

also, if u start from a terminal window, alt-spacebar, n will minimze the mirror screen so you can see the terminal window node_helper outputs… anything there?

usually a module.js error kills with MM screen…

Mine after upgrade it’s freezing when trying to run magicmirror. Also try both kms driver and fake kms driver.

mine is also freezing after the update.
No difference if i connect via vnc or using the monitor.

The only thing that does work, is opening the mirror in another browser (http://magicmirror:8080)
