Blank black screen | Noob

Arod192

So if I use Node serveronly I can see the mirror working just fine in my browser but as soon as I go into the terminal and type in pm2 start mm.sh that mirror is blank. I don’t know what else to do since this is my first time every working with a Raspberry Pi.

I also have two MagicMirrors opening on startup

Confusing … you say you have two instances MM ‘opening’ at start up, and yet you are also trying to manually start it using 'pm2'? You can not run multiple instances of MM. When the first instance boots up, it binds to the configured port, and any instances after that will fail because they can’t bind to that port anymore.

Along those same lines, you say you have two instances of MM ‘opening’ at start up, and you are trying to run it in 'serveronly' mode as well. Again, this will not work because the port is already bound to the first instance that came up. However, if after you execute the 'serveronly' setup, you don’t get any errors, that tells me you do not have any other instances running, despite you thinking there are two others running.

So a few questions:

do you have MM installed in different folders?
are you launching them from different folders?
when you execute 'node serveronly', where are you typing that specifically, which folder?

Arod192

Alright so at startup I have two instances running, one white and one black (both are blank).

I have another folder that I messed up in so I deleted everything in it and just renamed it to something else. Currently it is empty. While the other folder, MagicMirror, is a clean install.
Not manually. Is there a way I can disable MagicMirror from starting automatically?
3.I’m typing ‘node serveronly’ in the MagicMirror folder (It works fine here after I close out all other instances of MagicMirror using ‘pm2 stop mm.sdh’

KirAsh4

you can only run two separate instances of MM is they are on different ports, and for that to work, you will need two separate installations (in separate folders) because of the config file. They can not share it.
Check on 'pm2' documentations on how to delete any configured startup process

Alright so I fixed the problem of the two instances opening but when I run ‘DISPLAY=:0 npm start’ It’s still blank.

Any ideas on how to fix this? Like I said before it works when I use "node serveronly’

KirAsh4

Go back to the beginning. Move your current config.js to something else, like config.js.backup. Then grab the original config.js and try running that, see if it comes up.

You only need to set the DISPLAY=:0 if you are connecting remotely.

Arod192

Did it using the sample config and renaming it to config.js. I still get a black screen, but if I do “node serveronly” with the same files it works in my browser.

I’m getting no errors besides the “No helper found for module” (all of them)

KirAsh4

With the default config.js you get a blank screen when you try to run 'npm start' ? If so, what’s the hardware? Have you updated the OS? All variables.

I used the automatic installer located here, https://github.com/MichMich/MagicMirror, and followed every step.
I’m using a Raspberry Pi 3 Model B.
I’m running Raspian Jesse 4.4, Node v4.4.3.
The MagicMirror is up-to-date

@Arod192
THIS is the setup that worked GREAT for me:
https://forum.magicmirror.builders/topic/236/complete-setup-tutorial

(Surprised KirAsh4 did not mention it. Follow it step by step; first time around will take you 30 min, but after that you will fly through it). Work. It really does.

KirAsh4

@Arod192, that’s a rather old version of node. When you run the automatic install from MM², it installs a more recent version automatically. You shouldn’t have to do that manually.

KirAsh4

@amanzimdwini, I didn’t mention it … yet … because I like to figure out where the problem is, before I tell someone to start from scratch. :)

Arod192

@KirAsh4 Update Node.js and I’m still having the problem

Arod192

@KirAsh4 Okay I just changed the language from en to nl (just to see what’ll happen) and now it works!

But now everything is in the “nl” language but when I change it back to “en” the screen is black again

Arod192

@KirAsh4 Looks like all languages work but when I change the language to en I get a black screen

Arod192

@KirAsh4 Alright I think I fixed it. What I did was I went into the translations folder and I renamed en.js to en-us.js. After that I went into the config and changed en to en-us.

@Arod192 I can confirm this is a bug. Hardcoding ‘en’ in config.js causes black-screen, however, leaving it as ’ ’ or node serveronly runs fine.

noob here reporting same issue and same workaround works for me.

Exact Same issue and hardware and OS as poster. From a clean build, updated all before running MM auto installer as I thought I had made a mistake my first time around.

“used the automatic installer located here, https://github.com/MichMich/MagicMirror, and followed every step.

server nodeonly -works
npm start -does not

changing ‘en’ to ‘’ in config.js works as a workaround. It will now open in electron.

KirAsh4

Odd bug, as I have two different rpi 3s running just fine with 'en' as the value. This makes me wonder … can any of you paste the contents of your ‘/usr/share/X11/locale/’ folder?

$ sudo ls -aF /usr/share/X11/locale/

smithdsl

Hey Everyone,
I was have the same issue. Change from ‘en’ to ’ ’ now it works.
@KirAsh4 this is my “locale” folder.
