FYI, i have taken over maintaining this module and have made some updates. anyone interested can check out at https://github.com/dathbe/MMM-MyScoreboard .

open an issue if you have problems or a suggestion.

@BKeyport Awesome. Unrelated, but I love your MMM-Multimonth.

@sdetweil I like the idea of scheduling display times for pages.

Most of the rest of this it seems like I can do with Carousel–including giving the pages sensible names, and labeling certain modules to correspond with those pages–if, perhaps, in a bit more clunky way.

@sdetweil In case for some reason it’s helpful, I’ve reviewed the contents of /boot/config.txt from my two devices (4B gets errors, 2B does not).

In 2B, not in 4B:

#dtoverlay=vc4-kms-v3d
# see https://forums.raspberrypi.com/viewtopic.php?p=1507622#p1507247
dtoverlay=vc4-fkms-v3d

In 4B, not in 2B:

dtoverlay=vc4-kms-v3d

# Run in 64-bit mode
arm_64bit=1

[cm5]
dtoverlay=dwc2,dr_mode=host

@mdiorio Yes, it should not be hard to do if there’s a source to draw from.

@sdetweil It appears to load labwc by default, but either way it didn’t do anything different – fails to start with start:wayland and multiple phantom errors with start. I guess I just have to close my eyes and not read the logs on startup. Though weird it’s doing it with my Pi 4B, but not my Pi 2B.

@sdetweil Ok. When I have some time, I’m going to test an install with 32-bit PiOS.

@sdetweil

I tried all three options in raspi-config > Advanced > Wayland (those being 1) X11, 2) Wayfire, and 3) Labwc), and was getting the same error on all of them. I went back to Labwc because my understanding is that is the current recommended.

I’ve tried many different combinations. Anything having to do with start:wayland seems to truly fail and get stuck in a restart loop. npm run start:wayland technically works, but throws about 20 ugly error messages on start.

Various options I’ve tried:

# Work with error messages 
DISPLAY=:0 npm start

export ELECTRON_DISABLE_GPU=1
DISPLAY=:0 npm start

export ELECTRON_ENABLE_GPU=1
DISPLAY=:0 npm start 

# Cause endless start loop

npm run start:wayland

export ELECTRON_DISABLE_GPU=1
npm run start:wayland

export ELECTRON_ENABLE_GPU=1
npm run start:wayland

WAYLAND_DISPLAY=wayland-1
npm run start:wayland

DISPLAY=wayland-1
npm run start:wayland

@sdetweil
No luck. with DISPLAY=:0 npm start, I get the long list of errors, but everything seems to work ok with the mirror. with

WAYLAND_DISPLAY=wayland-1   
   npm run start:wayland

It throws other errors and gets stuck in what seems to be a restart loop.

0|mm  | [3351:0415/211257.942494:ERROR:wayland_connection.cc(199)] Failed to connect to Wayland display: No such file or directory (2)

@sdetweil

Is this still the right way to address these errors? This is what my ~/MagicMirror/installers/mm.sh file looks like:

#!/bin/bash
cd /home/mmuser/MagicMirror
'''
if [ $(ps -ef | grep -v grep | grep -e wayfire -e labwc | wc -l) -ne 0 ]; then 
   WAYLAND_DISPLAY=wayland-1   
   export ELECTRON_DISABLE_GPU=1
   npm run start:wayland
else
   export ELECTRON_DISABLE_GPU=1
   DISPLAY=:0 npm start
fi 
'''
export ELECTRON_DISABLE_GPU=1
DISPLAY=:0 npm start  

And I’m still getting the following errors:

Is there any functional difference between MMM-Pages and MMM-Carousel? I’m using Carousel, but just stumbled across Pages and am wondering if the grass is greener on that side…

@BKeyport Awesome. Unrelated, but I love your MMM-Multimonth.
