Turn off LED when signal is lost ?

[userXinos]

Hi, I think I'm missing something, but is it possible to turn off the LEDs when the computer is turned off (ctrl+alt+del)?

• firmware: firmware_WS281x_RGB.bin
• board: d1 mini
• OS: Fedora 39 (Plasma/Wayland)
• Software: HHDR v20.0.0.0beta2, and platform in web: Linux (V4L2)

Hi
I'm not sure if I understand correctly where is the problem. LEDs should be turned off on HyperHDR exit during the shutdown.

[userXinos]

Yes, it sometimes works, but for some reason the system sometimes does not exit hyperHDR, for example if turn it off via the ctrl+alt+del menu

Could you test installer from https://github.com/awawa-dev/HyperHDR/actions/runs/8215461902 it may have been fixed few days ago.

dnf says hyperhdr-20.0.0.0~Fedora_39~beta2-1.x86_64 is already installed

[awawa-dev]

dnf remove hyperhdr first

[userXinos]

mmhm, okay.

You run the app from the console, not service? Try to redirect HyperHDR logs to some file (also you can use --verbose option). Maybe HyperHDR process is simply killed so there is no time to do anything.

there is something more in logs later? about LED driver?

[userXinos]

I go to the web to disable & enable "Enable system capture" after start pipewire.socket

[awawa-dev]

no, before that. after you've stopper the pipewire was there anything else related to led driver?

[userXinos]

No. before stop I specifically pressed enter a few times and after that too

[awawa-dev]

there should be more at around ~23:57:50.093 I must finish for today because I can barely keep myself together (flu or something). I will let you know later. Probable there is another issue than that you fixed (Pipewire). Something related to LED driver but I must debug it.
