Hi, new Debian user here.
Lenovo ThinkPad X280 20KES8D300 running Debian 12 (Plasma, idk if important). I cannot get my keyboard backlight to work in any capacity (apart from mic mute, caps lock etc.)
Fn+Space does nothing.
xset does nothing maybe because of wayland.
There is no config file related to keyboard in /sys/class/leds
Any help is greatly appreciated.

Re: Keyboard Backlight not working.
Hi,
I've had this problem but never solved it. Now my current laptop doesn't have that feature.
I do remember trying the following:
Turn on the lights:
If nothing happens check if brightnessctl is installed and check for the device name:

Re: Keyboard Backlight not working.
Thank you for the speedy reply,
xset does nothing.
brightnessctl output is this:
All LED's work besides keyboard backlight.
xset does nothing.
brightnessctl output is this:
Is there any way to reconfigure the thinkvantage (I do not have that button) config file to make it act as the config file for the keyboard light? The max brightness suggests it might be possible?cal@Tomato:~$ brightnessctl -l

Does
I don't have a model that has a backlit keyboard and I'm using Gnome for the moment, so I am out of ideas now. Good luck!

Re: Keyboard Backlight not working.
No. Fn + Space does nothing.
I also doubt that a ThinkPad with a Touchscreen and LTE, which also has backlight markings on the space bar, would be missing the hardware for some reason.
Keyboard part number is 01YP052.
