@kellogg76 weird…

and if you do pm2 start 0 it works ok?

[kellogg76]

@sdetweil it works in as much as I can see the magic mirror on another computer when I point to the correct IP, but the pi itself does not display anything at all, it sits at a terminal prompt or if I reboot and let it try to start on its own it’ll switch from prompt to black screen with mouse pointer as if it’s trying to start, then it loops back to a prompt and cycles between the two states.

weird… seems like chrome is having trouble.

if you type

chromium-browser  --app=https://cnn.com

does it come up?

in 2.10, i created a similar script for
pi0w(armv6l) as electron doesn’t exist anymore

try this script

curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/run-start.sh >~/MagicMirror/run-start.sh
chmod +x ~/MagicMirror/run-start.sh

then

cd ~/MagicMirror
./run-start.sh

@sdetweil said in MM on Pi Zero fails after being off for a few days:

./run-start.sh

When I run

chromium-browser  --app=https://cnn.com

I get command not found, so I tried

chromium  --app=https://cnn.com

and I get Illegal Instruction.

i tried your script, and I get the text on screen about no helper found etc, then it gets stuck when trying to fetch the calendar data. I can access it from another computer but the pi is still blank on screen

Edit: It does seem to go through the calendar step but just very slowly, still progressing to each successive calendar now. I’ll leave it running and see if it eventually successfully starts.

@kellogg76 no… its stuck with the chromium-browser not loading…

I think u need to reinstall the chromium browser…

this means there was an update , or there is an sd card problem…

[kellogg76]

@sdetweil looks like the quickest fix is to re-install again. It’s a pain as I probably have to do this about once or twice a year. It can be working great then either the power will unexpectedly go out or I’ll shut it down for some reason and then it takes a full wipe and re-install to get it working again.

[sdetweil]

@kellogg76 use my install script

see here
https://github.com/sdetweil/MagicMirror_scripts

rename existing MM folder out of the way
run the install script… it does everything…

(well, not install chromium browser)
sudo apt-get install chromium-browser

[sdetweil]

@kellogg76 i have a system that is like that… power messes up everything…

I have moved to boot from sd card, RUN from ssd…

@sdetweil I renamed the old MM directory and ran your script

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

Everything went successfully, I can see the display from other computers but the pi just sits at a terminal prompt, is there something I need to do to start things off?
