How to hide desktop screen when raspberry turned on?

@bhepler - Nice, thank you.

FWIW, there’s lots of modules available for turning off/blanking the screen when not needed - that way you can leave the pi running (at minimal power use) and just have the screen turn off and on with a sensor or button…

@BKeyport or webcam in my case

@sdetweil I’d put that under “sensor” – but how do you do that?

[sdetweil]

@BKeyport i didn’t want to program for every webcam out there, so I found a system level library that does it

the motion project… it can do all kinds of video/pics on motion…

but it also can call a script/program when motion starts/ends… so I wrote a MM screensaver module that watches for the events from the external motion module… now my TV’s don’t support any cool way to turn off the display, so I hide all the modules… and show later on motion…

(and I use this same approach on a different smart-mirror that I found before MM)…
