The keyboard shortcut system does not detect the brightness button

Hello

The keyboard shortcut system does not detect the brightness button (fn9 and fn10) if I set it with other buttons it works!

What I can do?

Thank you

Devuan 2.0 ASCII with plasma 5.8.6, installed from devuan_ascii_2.0.0_amd64_netinst.iso

Which keyboard shortcut system do you mean? Also do you maybe have acpid installed? Do the keys work for changing the brightness?

I mean the shortcuts on the Plasma desktop.

Also do you maybe have acpid installed?
acpid is not installed, I will try installing it...
already installed acpid and restart the computer, there is no difference

Do the keys work for changing the brightness?
The Brightness keys f9 and f10 do not work, but if I assign the brightness to other keys they work.

Thanks

Re: The keyboard shortcut system does not detect the brightness button

acpid will not do much on it's own. You need to configure it. You can run acpi_listen as root to see if your keys trigger any event. I figure you want to bind brightness control to your brightness keys? As long as your keys trigger events binding 2 tiny scripts that change brightness by adjusting /sys/class/backlight/*/brightness using acpid (see http://www.thinkwiki.org/wiki/How_to_configure_acpid for how to bind them) should work.

On my thinkpad brightness keys work out of the box though so there might be an easier way for your laptop (not necessarily a thinkpad) too. Sadly i am not entirely sure what makes the keys work for me. Might be the thinkpad modules i've installed or it might be the bios. If it's the bios and that doesn't work in your case acpid might indeed be the best approach.

I installed acpid and run acpi_listen as root and it does not detect the f9 and f10 keys

At the moment it is best to simply change the shortcut to Meta F9 and F10, thanks to everyone.
