MM2 not loading text

Beth

hi i made my MM2 a year or so ago and it has worked fine but recently on boot it will show the mm2 screen and then not load the text it just shows a black screen i have tried to log into vnc but the RPI refuses the connection i tried swapping RPI’s and that didn’t work i also can’t open a command window or shut it down what should i do?

@beth run it in ‘dev mode’ and see what the output is.

@cowboysdude they can’t get into the machine… vnc doesn’t connect

Did the IP change by chance? Check to see if IP is static and ssh into pi that way.

Beth

@swvalenti how do i check?

sdetweil

@beth check your router to see if the system has a reserved address

u can find its address with
ifconfig command in a terminal window

ethxx is ethernet wired
wlanxx is wireless lan

@Beth what Sam said

Beth

UPDATE: there is a command window that papers on the boot up screen it does not leave i connected keyboard/mouse to it and can enter commands like a terminal window although pm2start will not work and npm start gives the following err (note i copied this by hand so there may be slight imperfections)

npm ERR! code ENOENT
npm ERR! sysca11 open
npm ERR! path /home/pi/package . json
npm ERR! errno -2
npm ERR! enoent no such file or directory, open ‘/home/pi/package . jason’

@beth said in MM2 not loading text:

/home/pi/

u are not in the MagicMirror folder for npm start

and its pm2 start (notice the space)

pm2 status will show u the pm2 currently managed apps

Beth

@sdetweil i did that and it gave me the following err:
[PM2] spawning PM2 daemon with pm2 _home=/home/pi.pm2
[PM2] PM2 successfully daemonized
[PM2] [ERROR] Script not found: /home/pi/MagicMirror/mm.sh

sdetweil

@beth said in MM2 not loading text:

: /home/pi/MagicMirror/mm.sh

ok, you used some old instructions, cause the file was moved to the installers folder a long time ago…

pm2 status
pm2 delete xx
where xx is the number of the line in the status (usually 0)
or the name in the line

pm2 save

then use my script to fixup pm2
see https://github.com/sdetweil/MagicMirror_scripts

the last command listed, fixuppm2.sh is the one u want to copy/paste to your terminal window

Beth

@sdetweil how do i use your script?

sdetweil

@beth said in MM2 not loading text:

how do i use your script?

it says

fixuppm2.sh, cut/paste this line into the terminal window on your device

Beth

@sdetweil also i did the command and it said to type pm2 save so i did (i don’t remember the txt) then it gave me a err and said if i want to force save to type pm2 save --force i did that and now when i plug in the pi after showing the mm2 screen it just goes to a black screen

sdetweil

@beth this is the line you copy/pasted

bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"

right?

u don’t need to git clone this repo, just copy/paste the line

sdetweil

@beth black screen is another problem… (but pm2 launched MM on boot, so pm2 is ok)

typically it means a library needed by one of the MM modules you are using is missing
(we removed some dead libraries, in 2.16 and 2.17, but many modules didn’t document needing them, so oops…)

SO, you need to look at the logs

minimize MM, alt-spacebar, n

then open a terminal window

ctrl-alt-t

then type

pm2 logs – lines=100

and look for module not found

we know about

request
rrule-alt
valid-url

Beth

i can’t “minimize” mm2 it is just a black screen with a terminal window it just shows the mm2 logo and to the left a terminal window (it is rlly weird and looks the same as the backround all black)on the bottom left (below the terminal window) it says dphys-swapfile.service

sdetweil

@beth that is something else.

do you have ssh enabled?

Beth

@sdetweil i don’t have ssh although i do have vnc

sdetweil

@beth I think that is hung before mm gets running. the bottom message is a boot time message
