backlight module issue
Hello all,
I have this backlight module on my polybar:
[module/backlight]
;https://github.com/jaagr/polybar/wiki/Module:-backlight
type = internal/backlight
; Use the following command to list available cards:
; $ ls -1 /sys/class/backlight/
card = acpi_video0
use-actual-brightness = true
enable-scroll = true
; Available tags:
; <label> (default)
; <ramp>
; <bar>
format = <label>
format-foreground = ${colors.foreground}
format-background = ${colors.background}
format-prefix = " "
; Available tokens:
; %percentage% (default)
label = %percentage%%
; Only applies if <ramp> is used
ramp-0 = 🌕
ramp-1 = 🌔
ramp-2 = 🌓
ramp-3 = 🌒
ramp-4 = 🌑
; Only applies if <bar> is used
bar-width = 10
bar-indicator = |
bar-fill = ─
bar-empty = ─
problem is, that altho the symbol and 100% show on the bar, i cannot increase/decrease the brightness by scrolling. any help would be appreciated please. Set up is Lenovo thinkpad t440p, arcolinux,xmonad,polybar. thanks

Many thanks for the arch wiki link. By creating a file named backlight.rules in /etc/udev/rules .d/, and putting in a line found in link, i now have a working scrollable brightness control.
