How I got my Magic Mirror working on a Raspberry Pi 0 (zero)

NoNameRo

@janth said in How I got my Magic Mirror working on a Raspberry Pi 0 (zero):
Chromium only shows a line at the top of the screen saying it can’t be run as sudo.

Any idea on how to fix this? Or how to get midori to work?

Thanks in advance :)

add --no-sandbox
for example - chromium-browser --no-sandbox --disable-infobars --start-maximized --noerrdialogs --kiosk --incognito http://localhost:8080

Thank you @NoNameRo !! It works now on Stretch. I can’t use localhost:8080 but xxx.xxx.xxx.xxx:8080 works fine.

Since initd is replaced by systemd, how do I run a script at boot up? For the last couple of days, I’ve been using a solution using pm2, but it seems to run the “node serveronly/” process multiple times so that my pi’s cpu has been at 100 % all the time.

Where do I have to place the script with
cd ~/MagicMirror
node serveronly &
sleep 45
sudo xinit /home/pi/chromium_start.sh
and how do I activate it for boot up?

have them under /home /pi/

Auto Starting Chromium


sudo nano /home/pi/startChromium.sh

#!/bin/sh
unclutter &
xset -dpms # disable DPMS (Energy Star) features.
xset s off # disable screen saver
xset s noblank # don’t blank the video device
chromium-browser --no-sandbox --disable-infobars --start-maximized --noerrdialogs --kiosk --incognito http://localhost:8080

	Control + X > Y > Return

sudo chmod a+x /home/pi/startChromium.sh

	Add the following lines before exit 0:

(/bin/sleep 30 && sudo xinit /home/pi/startChromium.sh) &

	Control + X > Y > Return
	
		sudo reboot

@janth - thanks I also used pm2 but your way is better.

But I have other problem - I do not see right modules on the mirror. There is no problem from the local net.
I checked top_right and bottom_right - same result.
I moved clock module from top_left to top_right and it became invisible.
Any clue?

@jpvalery I did have the same problem with black and/or white screen as you had, it seems it was related to the old v4.xx version of nodejs.

Once i installed the newest armv6 version (at this time: https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-armv6l.tar.xz) it started working in Chromium but not in Midori. Good enough for me though.

Hi,
I have Pi1, beend following the guide with the exception of installing latest software.
I was not installing wifi, using wired connection.

So now I’m on step 6
cd /home/pi/
sudo apt-get install git
git clone https://github.com/MichMich/MagicMirror
cd MagicMirror

all good, but on next command sudo npm install getting error message:

pi@raspberrypi:~/MagicMirror $ sudo npm install
/usr/bin/nodejs: relocation error: /usr/bin/nodejs: symbol , version GLIBC_2.4 not defined in file libc.so.6 with link time reference

epi

Anyhow, I did a fresh install and tried this both with the latest and originally mentioned software and it does not work. I think this guide is outdated.

Hello,

I tried running the instructions provided in the guide and I get stuck on running npm install . The error occurs when trying to download electron package. how did you all proceed.

I am running rasbian Stretch lite

Thanks

@chilln

How did you upgrade Node ?

@asaxena11

sudo wget http://node-arm.herokuapp.com/node_latest_armhf.deb
sudo dpkg -i node_latest_armhf.deb
sudo apt-get install npm

My problem:
I made fresh installation of whole magic mirror about 2 weeks ago because I had a problem with screen size - have huge black part of screen which is “covering” right modules.
I tried electronOptions, modifiyng the /boot/config.txt and without luck.
I am running 2.4.1 on fresh installation of Stretch Lite
