Hi all,
My problem is in the subject. I even cannot find anymore where ccould I set it. I have two ASUS laptops, from the K501U series, but they are non identical. Keyboard backlight is lost on both of them. The last 4.17.x kernel had/has keyboard light. I waited for updates but with the coming of 4.18.6 kernel the lights are still lost.

I didn't see a change with my Lenovo laptop, backlight is working as before. But I'm using the hardware key to activate (Fn+Space). I wouldn't know either how/where to do it from software/DE :o

Here it used to be Fn + F3 or F4 (dimming or brightening). There also used to be a slide control (among others), when I clicked on the battery icon on the tray. Now I got a new control for wireless mouse, possibly it measures the cherging of the bartery. It could be also set in system settings, but there is no such item. It looks like the os does not recognize keyboard backlight. I use KDE.

On 15.0, when I press such a key on my Lenovo Yoga using XFCE I see the commands executed by the keys on syslog:
<10.5> 2018-09-13 16:18:05 Legolas pkexec 19424 - - cer: Executing command [USER=root] [TTY=unknown] [CWD=/] [COMMAND=/usr/sbin/xfpm-power-backlight-helper --set-brightness 4200]

Well, not all keys: sound volume did not log.
The command above changes display brightness.

Did the same this morning. KDE/Plasma here. Ran journalctl and then pressed Fn+Space.

me too!!!
i have an asus G750J notebook, and i didn't notice, but for me there is also a change.
in KDE there is no more keyboard backlight control any more in the power settings which i had before.
default seems for my notebook, that the light is on.
as i didn't notice this change, i don't know WHEN it first appeared...

You are right, no control in system settings. For me it first occurred with kernel 4.18.0

Hi again,
Keyboard lights came back with the most recent upgrade. The slider to control it appeared again between that of display brightness and battery charge status.
