MagicMirror screen goes black



  • I gave you some bum steers on export XAUTHORITY=~/.Xauthority but prob was when I was using lightdm but for it to work omit that line.

    I have 2 monitors running well 1 really as the Chromium one isn’t really doing anything as all is working fine.

    xdotool.sh ended up just being

    if [ -z "$DISPLAY" ]; then #If not set DISPLAY is SSH remote or tty
    	export DISPLAY=:0 # Set by default display
    fi
    xdotool search --onlyvisible --class "chromium" key ctrl+F5  -v 2>&1 | logger &
    

    chrome-log.sh is just

    #Grep is a bit confusing as \| ie OR not AND so you get the following of Or + inline there is the other string
    #grep -q '8080\|ERROR' would return true if either exist (OR)
    ( tail -f -n0 ~/.config/chromium/chrome_debug.log & ) | grep -q '8080.*ERROR\|ERROR.*8080'
    sh xdotool.sh
    

    Main one for me is the PM2 one that waits for MagicMirror to say all is finished and point your browser

    ( tail -f -n0 ~/.pm2/logs/MagicMirror-out.log & ) | grep -q 'Ready to go! Please point your browser to:'
    sh xdotool.sh

  • i have a black screen too. Just got dark sky working. was finally happy and while rebooting after installing another module it goes to black. I thought it was my pi (3b) so I tried my other pi 3b+ and just black. I noticed earlier what looked like a draining battery icon but have no clue what that could mean. I do have a cursor on my black screen. alt tab shows Electon but I cant do anything from there. Help



  • @motdog run

    npm start dev
    

    Select the console tab, and scroll back to find any errors, red text.

    Usually black screen is syntax error in module.js



  • @sdetweil I can’t get to terminal. All I have is black screen with pointer on it. I’m sure it was when I copied a config



  • @motdog ctrl-shift-i



  • Thanks I’ll try in the morning. If I can somehow get to config.js I’ll undo what I did. Appreciate all of your help!



  • @motdog always make sure u have an alternative way into the system. Like ssh from your PC.



  • @sdetweil I use VNC viewer pretty much all of the time to access this and nothing happens. I do see the green light occasionally flash on the pi when I try with the keyboard hooked up to it & my tv.

  • So I am still getting this about every 3-5 days. I have now playing on spotify and am wondering if that is the issue. Dark Sky is my weather app but the issue I had with the number of requests is not an issue any more. Curious as to why this happens. At the same time I can see the screen via my remote module
