Good input. I did have to add option " -B pull-down" or it gave me syntax errors. sudo gpiomon --num-events=1 -B pull-down -f gpiochip0 9 && halt I also couldn't get it to register the button press immediately. I'd need to do more testing but it seemed I needed to hold it down for seconds before it'd register. I also wasn't sure how to get a wall message and 5 second wait in there, so in the end I went with a script that loads on startup. That said, what you said was a perfectly solid answer so you get the solution. Thank you for the response!

Hello. I've searched here, the Libre computer forums, even tried "cheating" with asking chatgpt. Using a "Le Potato" AML-S905X-CC with Armbian Jammy 22.04.2 LTS. I've gotten far enough to be able to read the switch on the GPIO with pulled to 0 reading as 1. button untouched: ~$ sudo gpioget --active-low gpiochip1 97 0 button pressed: :~$ sudo gpioget --active-low gpiochip1 97 1 From here though, I can't seem to figure out what to do next. I've seen suggestions to use a python script with a sleep to using device overlays. The device overlay examples I see using armbian are typically for orange Pis and I can't seem to extrapolate to the le potato gpio, or are Libre's support saying how to do it with their custom kernels and device tree overlay tools, which I (in my foolishness? long term wisdom?) chose not to use over Armbian. If anyone has some input on what to throw at this next I'd love it. I am using this le potato as a klipper server with Fluidd and would love to be able to hit my pretty led backed power button to power down the server board and a second led lit power switch to power down the printer. In the end it's no big deal if I can't get this working, I can just shutdown the pi via Klipperscreen and then use the modified power switch on the 3d printer. But that's not as much fun as changing everything. Thank you!
