speciall thx my dear. I have reached the problem in another way. I wrote this command into the rc.local:
su pi -c ‘/home/pi/mm.sh &’
And now I have the MM after reboot. I am so happy :)

I allready tried your way step by step. Everything worked but not the autostart of the mm. I just can start it manually with pm2 start mm.sh
Don´t know how to get a autostart for the mm.
Here is the information from the pm2 status:
┌──────────┬────┬──────┬──────┬────────┬─────────┬────────┬─────┬──────────┬──────────┐
│ App name │ id │ mode │ pid │ status │ restart │ uptime │ cpu │ mem │ watching │
├──────────┼────┼──────┼──────┼────────┼─────────┼────────┼─────┼──────────┼──────────┤
│ mm │ 0 │ fork │ 1123 │ online │ 0 │ 6s │ 0% │ 2.3 MB │ disabled │
└──────────┴────┴──────┴──────┴────────┴─────────┴────────┴─────┴──────────┴──────────┘
Use pm2 show <id|name> to get more details about an app

Ich have tested directly and with ssh. Ich will try to install pm one more time.

Thx for helping. I have done this in this way (but with pm2 start mm.sh) and I allready became the Raspian Desktop :(

I tested all commands with sudo at the beginning. The same problem. Is it maybe because of the command for reebot (sudo shutdown -h 0)?

thx for the fast answer. :)
I have done this way (just forgot to write down). I got this information after saving:
pi@raspberrypi:~ $ pm2 save
[PM2] Saving current process list…
[PM2] Successfully saved in /home/pi/.pm2/dump.pm2
but after reeboting I just see the desktop

so I tested new. It just needed a restart. Know Calender and News are working. But I have one more problem. Maybe here is somebody who can help?
The MM ist not starting after reboot. I followed the tutorial with pm2 and I can start it with pm2 start mm.sh manually. I also saved the mm.sh like it is written on the tutorial:
cd ~/MagicMirror
DISPLAY=:0 npm start
and I made the:
chmod +x mm.sh
and
pm2 save
but when I am rebooting I just came to the grafical desktop.

I just started a new try from the beginning with new raspian and editing the config.js . It worked but now i have a problem with showing calender and rss news. It is just showing load. Here is my code:
url: ‘https://calendar.google.com/calendar/ical/hXXXXXXXXXXX%40gmail.com/private-XXXXXXXXXXXXXXXXXXXXX/basic.ics’
url: “http://www.tagesschau.de/xml/rss2”
What is wrong?

Here it is [0_1479420812149_config.js](Uploading 100%)

I also tryed jshint.com with the script - he wrote me that there is one undefined variable but I don´t know where it is.

Hello,
at first speciall thx for this project and your great Tutorial, that is also working for noobs like me. But unfortunately I have a problme with the config.js and the mirror ist not really starting. I have a pi 3 Model B.
I allredy installed raspian freshly on the pi. Then I used your automatic installation with ssh. Installatoin worked completely . Then I installed pm2 - that worked, too. Now I could start the mirror with pm2 start mm . I became a black window with the Information, that the config file ist not there or not configured. But I allready changed the config.js.sample into config.js while doing sudo nano /MagicMirror/config/config.js.sample and saved this into config.js But the pi allready asks me for a working config.js File. Where is my mistake? Thx for support. Greatings from germany ;o) Hakupapa
