Turn off screen #174

Hi, is it possible, somehow, to turn the screen off while it is not used?

You mean like a screensaver?

SilasMueller commented 4 years ago

A screensaver would be one solution, yes. The best solution would be some kind of on/off switch that actually cuts the power of the screen. I dont know if this is possible to achieve with a software solution.

+1. I'm working on a small appliance. We need to turn the display off after about 5 minutes, and re-power the display if there is motion. (Similar to a tablet).

Can we get this prioritized? need to power off the screen in the night to save power. The official screen provides this. https://github.com/linusg/rpi-backlight

I have an embedded screen with my 3d printer, and I really hope the screen can be controlled by the power management system of Pi. It seems wiring two points then Pin 18 PWM can be used to change the backlight.

Hi, any progress of some sort on this ? Did anyone found a solution ?

I am using xscreensaver and it does help to dim the screen, but it does not turn off the backlight.
