Hope you have a lovely weekend and thank you again for working with me.

sorry try again

pm2 stop 0

then do

cd ~/MagicMirror
bash -x ./run-start.sh  >somefile 2>&1
wait 10 seconds, then ctrl-c

and post or send me somefile

my email is the same userid at gmail.com

pi@raspberrypi:~ $ which chromium
pi@raspberrypi:~ $ which chromium-browser
/usr/bin/chromium-browser
pi@raspberrypi:~ $

I’ve rebooted the pi before trying to start MM up again

BUT it should start chromium-browser

can u do

which chromium 

and

which cromium-browser

on a terminal window on the pi (or ssh session to the pi)

because electron won’t run, we launch MM in server mode
and then launch chrome over it…

i had a case where the previous server mode was still running, and so I don’t have to tell u how to correct that, I kill it…

pm2 job is to keep MM running… so, when the script ends, pm2 restarts it…
over and over…

oh by the way… the column on the pm2 status that looks like a circle with an arrow tip is the number of restarts… for your case at the moment, it should be going up

unless there is another problem…

do
pm2 logs --lines=50

pm2 status to show whats running

pm2 stop all

pm2 --help
for more options

Should the monitor that is connected (its connected via a microHDMI to HDMI and then an HDMI to DisplayPort adapter at the other end) automatically display once I’ve run pm2 start MagicMirror? Or do I need to take an additional step?

It indicates process successfully started, however the monitor doesn’t show anything.
I should note we’ve only ever ssh’d into the Pi from our desktops and I’ve never used a GUI connected to the Pi before, so very possible I’m not doing something correctly in that regard.

remove or rename the MagicMirror folder to some other name
the script assumes starting fresh
