Turn off display backlight after xx seconds

[graphiste]

Hello,
My octoprint is aways running and the display stays aways On.
Is it possible to have the display backlight turned Off after some seconds and get it On with touch?
I checked already the available settings, but those dont affect my setup (Octoprint aways running).
I have the official 7" RPi touchscreen V1.1

You have to edit your ~/.xinitrc. Just replace the that reads xset -dpms with something like xset +dpms dpms 600 1200 1800, just adjust the values to your need - more info available here: https://wiki.archlinux.de/title/DPMS

If its not too much trouble I could really use a dummy's guide for this. I was able to ssh and set the xset +dpms as above but that will reset on the next reboot. I don't know how to edit the xinitrc over ssh which is where a dummy's guide would help.

I really need this screen to go to sleep after a few minutes and then wake up if touched. I like to do overnight prints but the screen keeps my wife up at night and that's never going to fly, please help, thank you very much.

after SSH to the pi run sudo nano ~/.xinitrc, make your changes using your keyboard arrow keys to navigate, press ctrl + x to exit, answer y to save and press enter to overwrite existing file.

So im a total beginner but just had a similar problem the last view days.

xset q just spit out the error message Error: Can't open display: (null) for me.
After export DISPLAY=:0 xset q answered something, but this setting was lost at every reboot.
So I wrote export DISPLAY=:0 in .bashrc (with sudo nano ~/.bashrc)
Now you can edit the .xinitrc file with sudo nano ~/.xinitrc and replace
xset -dpms
with something like
xset +dpms
xset 60 120 180

After that you just have to disable the option "Turn screen off while sleeping" in Octodash under Settings or else it will turn off dpms again.
