SOLVED Screen shines black / Don´t know if it´s an Pi or Screen-Error?

[killing joke]

Hello @ all,

unfortunately I don´t know how to describe my problem excactly and therefore I don´t know if its in the right corner of the forum.

After I start my Pi (connected via HDMI to the screen) it works fine. The MagicMirror starts automatically after a few seconds on the destop.
After 10 to 15 minutes the screen turns black but is still on (the notebook screen shines on the backside completly white).
If I connect a mouse and/or a keyboard to the pi and press any key nothing happend, so it seems not to be a screensaver issue?!
On the screen menu I switched the screen sleep mode to off so it can´t be this issue as well?!

Is there an sleep mode on the pi or included in the MagicMirror code?
Any help is appreciated.

Thanks in advance

P.S.: Whenever I switch the screen off and on again it´s still black.

stop the auto run and goo to the magicmirror folder in the command line and type npm start dev

chek if ther are errors… bicase then the application is blank and your monitor is going in sleep…

When I go to the MM folder and type

npm stop

I got an errors:

npm ERR! missing script: stop

npm ERR! A complete log of this run can be found in:
nom ERR!            /home/pi/.npm/_logs/2018-07-26T14_14_20_020Z-debug.log

but I can´t open the folder because there is no folder like this.
So I can´t stop it?!

I can´t stop the npm aswell via remote desktop from Windows...

I´m confused

[jcklerk]

@killing-joke try pm2 stop mm or pm2 stop mm.sh

[killing joke]

It worked with

pm2 stop MagicMirror

after

npm start dev

there are some errors… but they appeared after I connected via remote desktop

@killing-joke
check if the screensaver is deactivated

On the screen the the screensaver is deactivated.

Is there an option on the pi?
