Stop the screensaver!

Anthony · Mar 12, 2019, 7:52 AM

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

@sdetweil
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 upgrade might 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 a sudo apt-get update && sudo apt-get upgrade although. It is always usefull. Thank you.

This is a screenshot of what happened after about half an hour after restarting magic mirror.
