Stop the screensaver!
-
Update.
Last 3-4 days my MM was running just fine without screensaver appears. Last night it happened again so I restart MM in dev mode to see if I find an error after the the screensaver’s black screen. When I moved the mouse (after some time the screensaver had appeared) the screen was white and in dev console I had a message saying websocket disconnected or something like that. Usually when I moved the mouse after the screensaver and without the dev tools enabled the black screen dissapears and I get my MM screen back. This time was different. I’ll try to upload a screenshot when I get home. -
usually when u see that the MM runtime has crashed for some reason… even the debug console is gone
I haven’t found a way to debug what has happened… I see this occasionally…
-
This is getting too weird. Yesterday I had the MM running in dev mode and after I saw the screensaver I moved the mouse and everything came back as normal and no errors in the console. I don’t know why this happens not all the time and with different characteristics everytime.

@Anthony when the screen went to sleep was the developer window hidden too?
when my MMM-SleepWake hides all the modules, the Developers console is still on the screen

In my case when the screen goes to sleep everything is hidden, modules, dev console etc. I see only black screen. Is there any possibility that pi “forgets” the setting to disable the screensaver? I will try to go and change this setting and after put it back again to see if anyhting changes. -
@Anthony interesting… neither of my systems has forgotten the screen saver setting, been running for over 2 years now…

@sdetweil
I don’t think that this is the problem but I want to test it just in case. -
At this point, I’m thinking a
sudo apt-get update && sudo apt-get upgrademight be in order. There could be a bug in the Pi’s power management routines. -
@bhepler
I will try this as well but 3 days now the problem does not appear. I haven’t touch anything on my MM and I don’t see the black screen. I will try asudo apt-get update && sudo apt-get upgradealthough. It is always usefull. Thank you. -
This is a screenshot of what happened after about half an hour after restarting magic mirror.
