Always on Linux Mint

I am using Linux Mint on a NUC that is connected to a TV at work that is always on showing some information. After some time, Mint just locks the screen. I don’t want Mint no go into standby or lock the screen. I tied deactivating it in the settings, but it seems to have some problems, and it still does lock the screen. Is there a way via the terminal to deactivate it for sure?

Is this setting toggle resetting, to the default position, after update/shutdown/etc.?

Just download caffeine. Then run it and it will show you an indicator when your system gets caffeinated, or when it can go to sleep.

Yeah, I’ve got Mint connected to a telly and yes it locks the screen.
