You have Pm2 install?

I have the script working, but the only way to start mm on boot, was set

pm2 start mm

on LXSession, but yes now once i boot my Pi, mm start without any problem.

I have the same issue, i did put java scrip on startup, i did look on the forum and #sebzx10r, suggest the same solution.

https://forum.magicmirror.builders/topic/1094/pm2-mm2-not-starting-on-start-up/15

In Raspian click Menu,Preferences,Main Menu Editor
Click Preferences and check Default applications for LXSession
Click OK and close main menu editor
Now click Menu and Under Preferences click on Default applications for LXSession
LXSession configuration opens
Click Autostart
Under Manual autostarted applications paste in your java command line
click add
close the LXSession configuration application and reboot your pi
your java app should run after reboot

Hope this help.
Cheers,

:D after fresh install the mirror did came to life :P
