New update Black Screen #1243

NicoMontanaro · 2018-04-01T14:45:56Z

Just updated to the last version of MM, but when i run the script i get just a black blank screen.

desq42 · 2018-04-01T15:01:11Z

…same here.

kikokazuma · 2018-04-01T15:17:11Z

Same problem here after updating this morning, even after a clean install. I was prepping this as a science fair project for my daughter due tomorrow so the timing is absolutely horrible, lol. Is there a way for me to install the previous version?

NPM log shows the following:

Dear 8 pound, 6 oz baby Jesus, save me.

MichMich · 2018-04-01T15:31:56Z

It seems the port is in use: EADDRINUSE 127.0.0.1:8080 Did you try rebooting you Pi?

kikokazuma · 2018-04-01T15:32:55Z

Yes, I've rebooted several times and even tried a fresh install of Raspbian + MagicMirror.

kikokazuma · 2018-04-01T15:33:20Z

Was working fine last night and broke after this morning's update, much like the OP.

NicoMontanaro · 2018-04-01T15:33:45Z

I did, but still no answer. Thanks!

MichMich · 2018-04-01T15:35:05Z

What commands did you guys use to update?

hermannw · 2018-04-01T15:35:12Z

Same problem here.

kikokazuma · 2018-04-01T15:36:08Z

As per instructions on https://github.com/MichMich/MagicMirror#updating

I ran this from the MagicMirror directory:

git pull && npm install

hermannw · 2018-04-01T15:36:37Z

Michael,

I used the recommended git pull && npm install.

NicoMontanaro · 2018-04-01T15:36:39Z

git pull && npm install

MichMich · 2018-04-01T15:36:42Z

Try disabling all non-default modules.

kikokazuma · 2018-04-01T15:37:47Z

Hi MichMich

Given I am running a clean install, would there by any non-default modules?

MichMich · 2018-04-01T15:38:49Z

@kikokazuma Not by default. - Any messages in your logs?

kikokazuma · 2018-04-01T15:40:11Z

@MichMich pardon my noobishness, is there a log I can provide other than the NPM log I posted above? If so, what command can I run to help?

Thanks in advance!

hermannw · 2018-04-01T15:40:41Z

Nope. Disabling modules did not help.

MichMich · 2018-04-01T15:41:26Z

AH, sorry, no that was what I was looking for (only noticed @hermannw 's log).
@kikokazuma You log states you are already running something on port 8080. Are you sure you're not running two instances at the same time?

MichMich · 2018-04-01T15:42:03Z

@hermannw Try disabling the updatenotification module.

hermannw · 2018-04-01T15:46:17Z

Nope. No change. I disabled everything except the clock.

kikokazuma · 2018-04-01T15:46:39Z

@MichMich Previously, if I ran sudo netstat -lnptu it would tell me electron was already running on that port.

Strangely, just one minute ago, I rebooted again and it seems to be working again.
Others reported similar issues: https://forum.magicmirror.builders/topic/6874/so-to-update-magicmirror-i-would

Something is/was going on.

MichMich · 2018-04-01T15:55:32Z

So, just to be clear @kikokazuma, it is working for you now? If so, what version of Node are you running?

Hurg84 · 2018-04-01T16:04:41Z

Hi MichMich, hi other Magicmirror Users,

I can confirm that after the upgrade the physical display stays black,
reinstalling electron doesnt fix the problem.

On the other hand ip:8080 in a Browser works, so it's just the mirror's browser.

Regards

Hurg

desq42 · 2018-04-01T16:08:07Z

Hi,

same symptoms here as Hurg84. Applications works remotely, but die Screen stays black.
Node -v -> v6.14.1

Regards

desq

kikokazuma · 2018-04-01T16:15:22Z

@MichMich correct. I rebooted again and it is still working for me.

If I run node -v, I get:
v9.10.1

Hurg84 · 2018-04-01T16:19:36Z

I got node v6.14.1 like desq42

hermannw · 2018-04-01T16:23:09Z

Opening from a browser doesn't work for me either.
I white-listed all IP's and the log says server is running but when I try to connect it says "Can't establish connection..."

MichMich · 2018-04-01T16:49:16Z

Could someone try the following in the MagicMirror folder:

npm install electron@1.4.15

If this works, please state your Node version as well. (node -v)

Hurg84 · 2018-04-01T16:53:44Z

@MichMich It works with node v6.14.1

Thanks :-)

MichMich · 2018-04-01T16:54:08Z

So an electron downgrade solved it for you?

bachoo786 · 2019-04-04T11:51:02Z

I dont use mmm pir sensor

sdetweil · 2019-04-04T12:32:02Z

Ok, two debug things to do

start mirror like this, from a terminal window

npm start dev &

watch for error messages in the terminal window
2. in the developers window (on screen)
select the console tab,
scroll up to see if there are any messages, errors in red text

bachoo786 · 2019-04-04T18:16:23Z

so this is the only error in red:

see image below:

bachoo786 · 2019-04-04T18:23:46Z

i just checked the api in openweather and it hasnt changed what else could it be?

sdetweil · 2019-04-04T18:44:03Z

401 sounds like the api-key for openweather wasn't specified correctly,

bachoo786 · 2019-04-04T19:18:40Z

so I removed the weather module all together and the error has gone however I now get this error:

and on my terminal I get this :

........
..........
  errno: 'EADDRINUSE',
  code: 'EADDRINUSE',
  syscall: 'listen',
  address: '::',
  port: 8080 }
MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection    ?

bachoo786 · 2019-04-04T22:17:15Z

So rebooted everything was working fine for few hours and now back to black screen

bachoo786 · 2019-04-04T22:25:54Z

Pm2 list doesn't show mm anymore it seems like its disappearing from pm2 until i reboot the rpi

sdetweil · 2019-04-04T23:40:20Z

pm can't help with, never could get it to work for me..

black screen after a few hours.. comment out the updatenotification module in config.js.. this has caused problems for a while..

a-wenzel · 2019-04-05T05:47:30Z

@bachoo786
sudo nano /etc/systemd/system/pm2-pi.service

check the paths... by default there are wrong for pi-user.

bachoo786 · 2019-04-12T12:38:15Z

@a-wenzel sorry just saw this.

how shall I check the paths? and what are the correct paths?

ukcdrf · 2019-04-14T17:01:14Z

I notice the same behavior as reported by bachoo786 above.
When launching the mirror with start npm & the mirror boots up nicely, reports the correct weather and correct news, but fails with the calendar and MMM-RMV modules.
The console reports that several modules have stopped.:

Whoops! There was an uncaught exception...
{ Error: listen EADDRINUSE 127.0.0.1:8080
    at Server.setupListenHandle [as _listen2] (net.js:1330:14)

  errno: 'EADDRINUSE',
  code: 'EADDRINUSE',
  syscall: 'listen',
  address: '127.0.0.1',
  port: 8080 }

Launching application.
Shutting down server...
Stopping module helper: updatenotification

Stopping module helper: MMM-RMV

However, if I list all running processes while my mirror is running I see four instances of Electron.
Is this expected????

sdetweil · 2019-04-14T17:47:04Z

That means another copy if mm is running already

ukcdrf · 2019-04-14T17:52:43Z

Any idea how this could happen and how to stop this behaviour?
I just ran the "standard" setup on a fresh Raspi using this command:

bash -c "$(curl -sL https://raw.githubusercontent.com/MichMich/MagicMirror/master/installers/raspberry.sh)"

sdetweil · 2019-04-14T18:16:27Z

The install script will register ANOTHER pm2 to start the mirror if one already exists

a-wenzel · 2019-04-14T18:53:32Z

@a-wenzel sorry just saw this.

how shall I check the paths? and what are the correct paths?

@bachoo786 My paste has the right paths.

bachoo786 · 2019-04-14T18:55:16Z

@a-wenzel thanks.. so the path is the reason for the black screen issue then ?

ukcdrf · 2019-04-14T19:15:33Z

@sdetweil
I just ran the script once.
I already formated and started from scratch 3 times, always with the same result.

Do you know where the script registers and calls PM2?
I would like to delete the call of the second instance there.

ukcdrf · 2019-04-14T19:24:02Z

@bachoo786
I have the same path as reported by a-wenzel and run into a similar issue as you.
Please try the following commands in a terminal window:

npm start &

When you see your black screen open another terminal window.
In the terminal window run:

ps -a

How many instances of **Electron ** do you see?

sdetweil · 2019-04-14T20:28:28Z

Pm2 will start mm at boot time if u start another u will see this kind of problem.

I don't use pm2 for this very reason.

Do pm2 list to see what is registered. Pm2 stop to shutdown some instance by name

bachoo786 · 2019-04-15T20:38:31Z

Guys magic mirror process has disappeared from my pm2 list.

What shall I do?

sdetweil · 2019-04-15T21:34:05Z

see the end of the mm/installers/raspberry.sh for the steps used to create a pm2 entry

bachoo786 · 2019-04-15T21:41:08Z

Sorry which part is that?

sdetweil · 2019-04-15T21:43:13Z

you will have to read the code in the batch file

bachoo786 · 2019-04-15T21:44:36Z

When I freshly installed mm pm2 was already installed with the mm process...why is that now it has disappeared?

sdetweil · 2019-04-15T21:45:56Z

i do not know.. i don't own this code, i am just advising what I know.

bachoo786 · 2019-04-15T21:53:30Z

Thank you

ukcdrf · 2019-04-17T17:44:32Z

@sdetweil and @ALL
Thanks for your help :-), I identified the error now.
I was using the Windows Remote Desktop tool to connect to my Raspberry and installed the XRDP package on my Raspi for this purpose. This is working perfectly fine, but the trouble is, that a remote desktop connection does not mirror the Raspberry desktop, but created an additional one.
Since Magic Mirror was autostart enabled, I got duplicated Magic Mirror instances without seeing them.
Now XRDP is removed from my Pi and I am using the default VNC which mirrors the Raspi screen and I no longer suffer from EADDRINUSE errors that kill my modules.

dstoianovici · 2019-06-26T18:08:30Z

Hello all,
I had the EACCESS error running MM on windows as described here fixed it by changing the port number from 8080 in config.js
