Lenovo Thinkpad T480s keyboard backlight

Hello

I recently got myself a Lenovo Thinkpad T480s. The keyboard on this laptop has backlighting.

I did some reading on the Arch Wiki, and apparently I'm supposed to have the following directory:

/sys/class/leds/tpacpi::kbd_backlight/max_brightness

However, I do not! I do not have the "tpacpi::kbd_backlight" directory.

Is there a way I can fix this so that I can get my backlight working?

If it's not too different from T440s I have, you should be able to do it by pressing Fn+Space; I have tpacpi::kbd_backlight in my /sys/class/leds, but I can't write into brightness even with root privileges, altho Fn+Space changes the value of tpacpi::kbd_backlight/brightness.

Thank you so much for this hint, it worked for me! (the tips from the arch wiki did not work for me)
