SSH startup

[djbenny07]

I’ve set it up and it all works however i am unable to start the service via ssh and get the message in the screenshot attached

[geeflaxx]

i think a lots of beginners have the same error

@djbenny07 Try to add "DISPLAY=:0’ in front of your command. Do you really need “sudo”?

[Alvinger]

Also make sure that you enable X forwarding in the ssh call, e.g. ssh -X user@host.

[KirAsh4]

DISPLAY=:0 is a must when attempting to start MM through an SSH connection, otherwise it simply doesn’t have a clue what display to use, the one you’re sitting at, or the one on the rpi?
X-Forwarding is not required nor necessary for a simple ssh login, startup, and exit.

[geeflaxx]

i could you say that i don’t have the electron order.

and display=:0 isn’t it for vertical view?

@geeflaxx The display=:0 parameter is to send the output of the electron process to the monitor attached to your Raspberry Pi.

Rotating the display is done by editing the /boot/config.txt file and adding the line display_rotate=1

[KirAsh4]

The ‘DISPLAY=:0’ bit is simply telling the system (in this case the rpi), which monitor it should use, in this case, the attached one.

For rotation, using ‘display_rotate’ you can tell the OS how to rotate the output:

display_rotate=0           Normal
display_rotate=1           90 degrees
display_rotate=2          180 degrees
display_rotate=3          270 degrees
display_rotate=0x10000    horizontal flip
display_rotate=0x20000    vertical flip

a little question:
how i can delete my “desktop” and start with my npm (so i wanna after a restart direct to my npm not on my desktop)?

[KirAsh4]

You can’t. You need the desktop to run electron which is what displays the mirror. What you can do, is run an automatic (re)start of the mirror. For instructions, please visit https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

[geeflaxx]

thanks, but they don’t work
i create the script, and i saved it in the pm2
but if i restart my magic mirror they begin in the desktop
and if i use ‘pm2 start mm.sh’
they go to the mirror

with the command ‘pm2 show mm’ i see that is a x in the field “watch & reload”
what now ?

[KirAsh4]

Then you didn’t do it correctly. Did you launch it, then save the task? You have to follow the steps one by one. Please go back and start from the top and do it again.

i only did it

[KirAsh4]

There’s a glaring instruction right there on the screen that you did not follow. When you typed in pm2 startup it clearly told you what you need to do, which I don’t see anywhere in your command log. I’m sorry, but if you can’t follow directions given to you, there is really not a whole lot anyone can do to help you. The instructions are there for you to follow, please do that.

@bhepler I try to enter ‘display_rotate=1’ in the config.txt file in the boot folder. I try to save the file and overwrite the previous version of the file to only get the message “can’t open file to write”. Where am I going wrong on this?

@Stehman07
you need to edit the file as root, the normal user pi does not have sufficient rights.

Run sudo nano /boot/config.txt instead
