@tomyboy96 test with pm2 start mm.sh in crontab -e then and see if that works

have you put pm2 start mm in crontab? if you havent you can do so with
crontab -e then type @reboot pm2 start mm at the end of the file then restart it to test

On the Module MMM-SL’s github it says
“updateNotification The notification to listen for. If received then will trigger update of departure times.”
and
“I recommend that you don’t update it with a timer, otherwise you will see that after a while you will get an error message instead. The recommended way is to trigger the update either with a button or similiar.”

but i have no idea how to actually trigger the update and i havent found any guidance on how to do it on the modules github,
if anyone got the answer it would be to great help

After you type nano x11vnc.desktop you should type

[Desktop Entry]
Encoding=UTF-8
Type=Application
Name=X11VNC
Comment=
Exec=x11vnc -forever -usepw -display :0 -ultrafilexfer
StartupNotify=false
Terminal=false
Hidden=false

which causes x11vnc to autostart
