Backlight key on XPS 13 9360 with 8th gen CPUs

Hi,
I'm trying to get backlight keys (fn+f11/f12) working on my new laptop.
When pressing fn+f11, all I get is this:

FocusOut event, serial 34, synthetic NO, window 0x1800001,
    mode NotifyGrab, detail NotifyAncestor

FocusIn event, serial 34, synthetic NO, window 0x1800001,
    mode NotifyUngrab, detail NotifyAncestor

KeymapNotify event, serial 34, synthetic NO, window 0x0,
    keys:  1   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   1

is this a proper key event?

Please provide more info. Where do you get this? What are you trying to do? What is your problem? Is something not working properly?

As gkaklas said.
Also, how are you planning on increasing/decreasing KbdBrightness? Some laptops has this on a firmware level, others dont.

I am using this script: https://pastebin.com/fmjVt4p5 on my MacBook running Arch to change brightness up and down (passing - or + arguments), and bound the commands through my WM.

Otherwise, how to config you keyboad backlight is described on the Wiki here: https://wiki.archlinux.org/index.php/De … _Backlight
