@vinnie1 did u add the
export ELECTRON_DISABLE_GPU=1

to the correct file

vinnie1

@sdetweil

yes

/MagicMirror/installers/mm.sh

I also have a mm.sh in my home directory (not sure why), I put it in there as well.

@vinnie1 to figure out which script needs updating use pm2 commands

pm2 status

will show you all the apps it is managing

for each, using the number or name do

pm2 info x

where x is the number or name
for example
pm2 info 0
or
pm2 info MagicMirror

it will tell you lots of things, but one is the name of the script used to launch the app

With all my fiddling, my MagicMirror is now broken, it wont start.

Over the next few days I will do a clean install, and then take it from there.

Thanks for your help.
