Dear @nathanRamaNoodles,
your backlight_dimmer fork is a great idea, so I appreciate it!

I'am trying to integrate it on my raspberry pi 3b+ with the official 7inch touch display running in kiosk-mode with FullPageOS distro (version 2019-12-01_2019-09-26-fullpageos-no-acceleration-buster-lite-0.11.0.zip) with no success.

After installation, when I fire the command 'sudo ./timeout pi 30 event0 event1' nothing happening.
Do you think my problem it will be the input device?

hi nathan,

i'm trying to get this working with dietpi on my raspi 4 with 7 inch touch screen.
when i'm trying to start it it get "display-manager.service not found". i don't know if the cause is dietpi or backlight_dimmer... can you help me on that ?

best regards

two questions i hope you can answer:

1st:
will your modified backlight_dimmer program work also with a touchscreen hooked up via hdmi (picture) + usb (touch input) ?
2nd:
do you know if it's possible to combine your modified backlight_dimmer program with the pi camera motion detection described here: https://www.youtube.com/watch?v=PGxpndmnYyY
(= wake on motion)

i'm planning to use your script for another pi hooked up to big touchscreen (hdmi + usb) and want to use the pi camera for motion detection. if a motion is detected the screen should wake up and go to sleep after a defined time ...

Hi @nathanRamaNoodles ,

your backlight_dimmer works great. Appreciate it.

However, is it possible to make the screen stay on when a video is playing in chrome or kodi is running with a video or slideshow ?

Actually screen will get turned off, no matter if any media is playing or shown...
