@sdetweil ok thx

@chndrcks said in Blank Screen in Electron - fresh install on Pi Zero 2 W:

line 55 “if [ 0 -eq 1 ]; then

yes I just disabled that section. for install the log has to be outside the MM folder
(as it doesn’t exist yet, until the git clone, a long way down)

@sdetweil Thank you for the useful hints! I will soon work on them, and consider making a pull request to the community.

@reilley

It works. Thank you

@Amenity4882 its solved

glad you found it

@sdetweil, great, thank you very much!

@frustrated said in MagicMirror/node_modules/electron/dist/electron exited with signal SIGBUS:

I did do a reboot just to be sure everything updates.

yes, for sure… but did it work BEFORE rebooting??

anyhow…

you also have a backup of your mm, right?

if not, see
https://github.com/sdetweil/MagicMirror-backup-restore

and can be versioned with git …

It seems to come up most often when I load the MMM-Pinfo module in my config, though I have seen it at other times as well. The problem is that I don’t see enough information in these logs to find a source myself.

Steps to Reproduce: Load MM, usually with MMM-Pinfo module enabled.

If anyone has any ideas, that would be great.

pinfo doesn’t use fetch…

Sadly, best way is to comment out, or disabled:true
each module til you find the culprit

@Pade2204 i’m surprized that its running…

just to check

output of

grep version ~/MagicMirror/node_modules/electron/package.json

@sdetweil I am running raspbian (debian 11 bullseye) with no pending updates on a pi3B+.
I have cd’d into MagicMirror/fonts, run npm install and restarted the MM. No change. Still displays a square where there should be an icon.

@Dresch360

The Pi5 has new GPIO hardware. It is not compatible with software written for earlier Pi models.

So look at what gpio library is being called by the modules you are wanting to use.

I’ve been rewriting my own code to use gpiozero .
gpiozero works and isrecommend by raspberry pi foundation and works on older pis too.

Lgpio works on rpi5
Gpiod works on rpi5

Pigpio WILL NOT WORK
RPi.GIPO WILL NOT WORK

I haven’t tried rpi-lgpio which supposed to be a drop in replacement for rpi.gpio.

@sdetweil Just letting you know that this fix corrected my issue where my calendar module (setup for iCal) would not show repeating events. The repeating events are showing again. Thanks.

@pencilsharpener I saw. thank you

@davismorehead I updated the installer (raspberry.sh) to use the

systemctl get-default

command instead of looking at the file…

thanks for the info

@sdetweil Thank you for all the help.
The mirror is at my family’s house. So I have to find a way to VPN connect myself to that.

I will come back to you asap.

@jbat66 I opened this issue, with a sample testcase

returned date incorrect caused by TZ rollover #610

@tacotaco

I know this is an old issue, but I had this happen to me while setting up MM on a Le Potato board.

Seems like a GPU issue, and you can bypass this by adding this snippet right before you call npm start:

export ELECTRON_DISABLE_GPU=1

In my case, I’m using PM2 to manage startup, so my ~/mm.sh file looks like this:

cd ./MagicMirror export ELECTRON_DISABLE_GPU=1 DISPLAY=:0 npm start

I don’t know the full extent of the issue, but I know that this works and allows me to run MM.

Hopefully this helps you and anyone else looking for this in the future.

@sdetweil “one event with recurring for f/s/s will be 3 events. 1 for each day”

Totally fine with that. That’s what I have now, but now I have much less typing.
