@sdetweil I have about 5 that are sourced in Google and another 2 or so that are subscription-based (i.e. sports teams).
The way that I am starting MM is via ssh since my monitor is inside a frame up on a wall, making it a challenge to connect directly. The script I use is:
sudo -u rudin-fam
DISPLAY=:0
XAUTHORITY=/home/rudin-fam/.Xauthority
nohup chromium --kiosk http://localhost:8080
–noerrdialogs
–disable-infobars
–disable-session-crashed-bubble
–disable-restore-session-state
>/dev/null 2>&1 &
