Please let me know. If you make It work could you share It as an ISO ti flash? Would be so good

So i mad the MM start after a lot of troubles (https://forum.magicmirror.builders/topic/6060/failed-at-the-magicmirror-2-2-2-start-script-sh-run-start-sh?page=1)
Now the problem is that the display/vncview stays black, no module shown. What can i do?
This is the console log from vnc

~/MagicMirror $ npm start

> magicmirror@2.2.2 start /home/pi/MagicMirror
> sh run-start.sh

If i start without anty config i still get a black screen (compared to the old error message about the config file)

@cruunnerr after an auto install without sudo, made it work starting the installation of electron for the 2nd time in it’s folder. Now everything runs smooth if i give him commands but 1:
-server only does not work, i can’t access it remotely
-pm2 start does not work, the display goes all black but no module is loaded, it stays black. I tried with both my old config and the example config
-maybe local launch does not work too? i have no idea since it’s really hard to connect a mouse and keyboard. If i use a VNC can i start it with npm start only?
any idea?

@cruunnerr From when sudo is a bad thing? I’ll try now

@Homerj could you share it?

@Homerj i’m desperate, 2 days no result… i’d love an img to flash with everything working… anyone?

@cruunnerr I went to jessie, tried again… it failed… reinstalled electron 3 times… still fails… always the same damn error…
i think i’m gonna build my own webpage with blackjack and hookers…

This is so incredible…
