csd for keyboard backlight brightness doesn't show up #429
Description
csd for keyboard (similar to audio one like this image)
not shown up,
after digging, I find out that is because for some reason the shortcut for stepping up and down for the keyboard backlight is not detected by X11 (I didn't test on wayland thought) (I tried testing that by using xev)
but...
It is working on Gnome!
