Black Screen with some modules + linux-armv Error

[JohnGalt]

New install, using Sam D’s install script on buster: It runs OK with default modules as well as MMM-Worldclock [the MM displays on the local monitor, as well as from another machine using the browser]. When I enable either MMM-BackgroundSlideshow or MMM-DynamicWeather I get both a black screen on the local display as well as the web server stops as evidenced by being unable to connect in a browser from another machine. The first thing that catches my eye in the logs is an error that the linux-armv7 binaries cannot be used on the linux-armdefault platform. I am running on a Raspberry Pi 4. Any ideas of what went wrong?

Logs output:

@johngalt said in Black Screen with some modules + linux-armv Error:

MMM-BackgroundSlideshow

yes, this module uses a library,

MMM-BackgroundSlideshow/node_modules/sharp

which has a problem now on 32bit systems…

is reported in the module github… no fix found yet

[JohnGalt]

Sam - thanks. Do you happen to know whether this is also true for MMM-DynamicWeather?

[sdetweil]

@johngalt looking at the code and package.json

its this
https://forum.magicmirror.builders/topic/15778/fix-for-black-screen-in-2-16-and-later

[JohnGalt]

@sdetweil - thanks. I may just disable the two offending modules for now, and then dig thru that post.

[BKeyport]

@johngalt Disable Background slideshow, then dig through the post - dynamic weather will work after you do the steps in the post.

[JohnGalt]

@ BKeyport - thanks. I’ve disabled that module and found one that works. I will work on the MMM-DynamicWeather, hopefully today. Thanks to you and Sam for the support!

[BKeyport]

@johngalt What did you end up using for the background? I’m in the same boat.

[sdetweil]

@bkeyport I use MMM-ImagesPhotos, I added some stuff to retain the image aspect ratio, not cover or contain which both distort the image… then added support for color or blur fill outside the image…

loads from a folder in the module folder (altho that can be a link to wherever, I link it to my file server)

https://github.com/sdetweil/MMM-ImagesPhotos

my uploadPics module will take images from your qr connected device and put them in whatever image storage location u like (it defaults to the ImagesPhotos location (‘uploads’)

I am trying MMM-SimpleBGSlideshow, but may try the one Sam is using. I do have this one up an running, but it appears to have limited functionality.
