Black screen after MM v2.4.0 update.

A Former User

After 2.4.0, Asus Tinker Board cannot display MM. I think it might be related with this openGL issues. Is there any way to solve this?
ATB has no openGL desktop driver like vc4-kms-v3d. Fake vc4-kms-v3d does not help.

I can’t access my mirror remotely anymore. Will I need to format my sd card and try again?

I am having the same issues and tried alot right now.

Tried the
dtoverlay=vc4-fkms-v3d as well as dtoverlay=vc4-kms-v3d as well as deleting that phrase

I downgraded electron to npm install electron@1.4.15 since i found that helped in the V2.30 problems.

I cant currently show the log from starting MagicMirror since i remotly access it and the MM just goes “all black” over the remote-access-page and I cant close it.

I really just want to downgrad the MM to 2.3 since it worked absolutly fine with it…

Additional software I use is MM-PIR

Thanks Mykle1
Just how do i tell my pi to get the specific version? I am not versed in programming or coding or anything and couldnt find something online that told me how to install a specific version

Did anyone find a fix here? just updated and same thing here. Hopefully i can get this back working tomorrow.

@kastore

One way is to go to that link I gave you and download the version you want and install it manually.

Bumping this because I’m also having issues. A lot of time on google says it’s not just a MagicMirror issue, but lots of people have problems with the OpenGL drivers. My screen is blanking after some time no matter what, but I also found the hard way that it messes with tvservice (like the Remote Control module uses) – turning my HDMI off straight up insta-shut down my pi! Gonna have to keep researching for sure.

I just updated and this is shown at the end of the install.


MagicMirror installation successful!

I applied

dtoverlay=vc4-kms-v3d

to the config.txt ( also tried with fkms)

Reboot and I get a black screen.

When I remove dtoverlay=vc4-kms-v3d then the mirror boots up.
Any suggestions?

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.

Kimzer

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

thenameiwantedwastaken

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.

sdetweil

@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.

Dom1n1c

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)

Kimzer

Is there a different way to turn the screen on/off with the fake kms driver maybe? :s
