FW 16 Keyboard backlight

No mention of OS. As procedure fails inder Fedora 40, I’m assuming windows.

It works under Linux as well.

Thanks. Please post the udev rule(s)

The instructions are in a collapsed section, which you can click to show. Sorry, that wasn’t clear. I edited it.

No, initially it was snaps, but I changed to regular deb packages for this

Not brightness, cycles through different breathing speeds. All I want is for the backlight to actually stay on, but so far nothing allows that to happen.
