MM keeps freezing

@requiemmg - I have some general troubleshooting suggestions, but unfortunately nothing approaching a solution.

For starters, you can examine the system log at /var/log/syslog which may give you some insight to system-level events. My gut tells me it’s a power problem, but my gut is notoriously bad at debugging.

Since you have two mirrors, I would back up your config.js file on one and sacrifice it to the troubleshooting effort. Reflash the SD card, format the USB and reinstall Raspbian. Perform a barebones Mirror installation on it using @sdetweil’s script. Do not install anything other than the OS and Magic Mirror framework. Then wait and see if the freeze behavior affects the slicked mirror.

If the rebuild mirror stays up, start adding things one at a time. I would start with the Lights-Out client as it is unknown to me and I am inherently suspicious of it.

Thanks. I have never seen the lightning bolt icon on any of the mirrors displays. I use the USB output of the display controller. Power comes from this https://www.amazon.de/gp/product/B01AA83VHA/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 and is attached to this display controller: https://www.amazon.de/gp/product/B0756ZBB2G/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

@requiemmg IIRC, the lightning bolt went away with Raspbian Buster.

@requiemmg Did I understand correctly that the display controller powers the Pi via its USB port? If so, I very strongly believe that this might be the source for the problem for two reasons:

The USB port does not provide enough power for the Pi
If the display controller goes in standby, then probably the power provided via its USB port might also be reduced.

I would always recommend to connect the Pi directly to a dedicated power supply, which can supply min. 2.5A.

@Fozi Oooh, good call. Strong power is good power. Part of the reason I upgraded to Pi4’s for most everything, honestly. Got tired of the weak power supplies on the old USB spec, so…

requiemmg

Okay, I’ll try this. Did also not know that the bolt signal is no longer available with current Raspbian.
Oh, the controller does not enter standby, I have it running 24/7.
Ordered a power supply with 3A to be sure. I’ll report back.

BKeyport

FYI. the bolt is still active, fresh copy of the OS downloaded from their website, on RPI3b+. whipped it together so to test for mirror frame placement.

@BKeyport - Good to know, thanks.

requiemmg

So, both mirrors are now running on an external 3A power supply.
Unfortunately, the still keep freezing. I fear that I have to setup from scratch, step by step, to see what is causing this. :-(

BKeyport

Yeah, that would be a good idea, who knows what got screwed up on the old SD cards with the freezing.
