MagicMirror stays black, but loading from another browser (Windows, Android) works

ok, I found a simply way to make chromium start in full screen mode, but how do I have to disable electron from entering full screen?

AnduriI

well that didn’t worked. I still only see a black monitor. I did also reinstall MagicMirror and connected to it via VNC. Strange thing is that I can see my MM on my VNC client, but not on my monitor. I didn’t even thought this would be possible…

@andurii, I have no idea then. It worked perfectly for me. I’ll have to take a look at my configuration and let you know. I am currently traveling so I can’t look at the moment.

@andurii Hmm… Sounds like your monitor has gone to standby.
Login via SSH:

Make a sh file named: monitor.sh

Add the flowing to the file:

#!/bin/bash

if [ "$1" == 'on' ]; then
  tvservice -p;
  chvt 6;
  chvt 7;
fi

if [ "$1" == 'off' ]; then
  tvservice -o
fi

Then make it executable with: chmod +x monitor.sh
Turn on them monitor it like this: ./monitor.sh on
Turn it off like this: ./monitor.sh off

And of course, make sure you are on the correct input to actually see the Pi… :)

That should “turn on” (or off) the screen from SSH. :)

trying your script or chvt 6 [or 7] manually does result in this error:

Konnte keinen Dateideskriptor finden, der auf die Konsole verweist.

The monitor is turning on correctly and I can see the background dark grey in the mirror, but it simply does not show the mirror. Maybe it somehow has multiple desktops defined and just showing the wrong on hdmi output…

@andurii Yep, that definetly sounds like your monitor just went sleeping.

@andurii I get the same error message “Couldn’t get a file descriptor referring to the console” but the monitor turn on… :)

I have tow desktops as well, the Mirror shows up on one of them… I can use (in VNC) CTRL + ALT + Right or Left arrow key to switch between virtual desktops.

that only works for PI devices where tvservice command exists… I run MM on an ODROID so, that doesn’t help…

I also use an EnergyStar TV, which freaks out when the video input signal is cut and then powers off after 15 minutes…

AnduriI

I did use CTRL + ALT + RIGHT or LEFT, but that didn’t helped either. Only change was that in the middle of the VNC-session was a small blue notification saying Desktop 1 so I suppose I have only one virtual desktop active.

AnduriI

well something strange I noticed… (don’t know if that’s related)
My Desktop used to be PIXEL I think (this nice road wallpaper and menu bars at the top. Now it looks like it is running Openbox. I don’t know how this happened, but it was not intended by me. Was that changed in the newest version because of my upgrades?
