Problem server client configuration

Akkor

Hi all
I have a MM on my Ubuntu server and it seems to work fine, i can watch on 192.168.x.x:8080 on my browser.
Now the question is…the only way to watch the mirror on a Raspberry pi3 client is by chromium or there is a way with electron ?
I tried to change my mm.sh with: node clientonly --address 192.168.2.100 --port 8080 but I got error:

pi@raspberrypi:~/MagicMirror $ node clientonly --address 192.168.2.100 --port 8080
Client:
(electron:1213): Gtk-WARNING **: cannot open display:
There something wrong. The clientonly is not running code 1

Some help to solve ?

@akkor Are you trying to start the MagicMirror via an SSH connection?

You can’t start an MagicMirror instance via SSH: https://github.com/MichMich/MagicMirror#installation

@idoodler I have tried to start changing the mm.sh
This is the command I’ve put in:
cd ~/MagicMirror
node clientonly --address 192.168.2.100 --port 8080

but when I restart raspberry the system show me only the desktop and MM seems don’t start

@akkor Ok, check the log with the following command: pm2 log mm

On the top you will see the last 15 lines of the error log.

This is the answer

pi@raspberrypi:~ $ pm2 log mm

Pls help I cannot find any solution

if you are trying to start over an ssh session, you need to add this before the node clientonly

if [ -z “$DISPLAY” ]; then #If not set DISPLAY is SSH remote or tty
export DISPLAY=:0 # Set by default display
fi

@akkor - Ugh. Why would you want to use Electron if you didn’t have to? There’s already a web browser on your Pi. Just point it at the MM server and be done with it.

I’ve learned that you can get Chromium to start in kiosk mode at a particular URL with about an hour of research and testing. Minimal swearing was involved.

@bhepler Electron is already a premade solution that works great. However using Chromium in Kiosk mode is also a nice and easy solution. And it may solve the issue here.
