Nevermind -

my last two replys are not published yet.
Anyway - I read about a smiliar problem and tried the following:

• backup MM folder
• use your install-script
• removed module and config-content from backup to new folder

MM starts up as intended.
No idea, what was the issue exactly, but after your installation-script-usage it works as a charm.

Thanks for support!

backup MM folder
use your install-script
removed module and config-content from backup to new folder

also, I have backup/restore scripts that will do that AND allow you to keep different versions, AND save on github
NOT on local machine where it might be lost
only saves the config, custom.css and a LIST of the modules (where from)
on restore, reinstalls all the modules (in case node.js changed during the time between backup and restore)

Unfortunately not:

ozone_platform_x11.cc(245) Missing X server or $DISPLAY
env.cc(258)] The platform failed to initialize.
/home/pi/MagicMIrror/node_modules/electron/dist/electron exited with signal SIGSEGV

pm2 stop all
cd ~/MagicMirror 
npm start

does it come up?

Perhaps I should have named the title “MM not showing” instead of “MM not starting”.

U’re absolutely right. Just removed the handy PIR-script and installed PIR-Sensor-Lite and forgot the “”. My bad.

But: Beaviour is like before. I can start the process and access the MM via Browser but it does not start on the local display.

What works is:

Browse the MM-IP from whitelistet IP. That’s nice but I’d like to have the MM just showing via autostart on the display which is attached to the PI:(

@sdetweil Thank you for your reply.
You’re talking about this script?

Do you have a further advice? Thanks in advance!

if you had used my install script this was a choice
there is a separate script so yiu can add pm2 later
