Hi everyone,

I’m trying to set up keyboard brightness control with notifications on my 
Qtile setup. Here’s what I’ve done so far:

   - 
   
   I’ve created key bindings for F2 and F3 to adjust the keyboard backlight 
   brightness using commands that modify 
   /sys/class/leds/asus::kbd_backlight/brightness.
   - 
   
   I want a notification to appear each time I adjust the brightness, with 
   different icons for "Brightness Off" and "Brightness On".
   - 
   
   My current key bindings look like this:
   
   Key([], "F2", lazy.spawn("bash -c 'echo 0 > 
   /sys/class/leds/asus::kbd_backlight/brightness && notify-send -u normal -i 
   $HOME/.config/dunst/icons/keyboard-backlight-low.png \"Keyboard Backlight\" 
   \"Brightness Off\"'")),
   Key([], "F3", lazy.spawn("bash -c 'echo 1 > 
   /sys/class/leds/asus::kbd_backlight/brightness && notify-send -u normal -i 
   $HOME/.config/dunst/icons/keyboard-backlight-high.png \"Keyboard 
   Backlight\" \"Brightness On\"'")),
   - 
   
   However, I’m not seeing any notifications when I press F2 or F3. I’ve 
   verified that notify-send works in other scripts, and I also confirmed 
   the icons are in $HOME/.config/dunst/icons.
   - 
   
   *What I’ve Tried:*
   - Checked the icon paths to make sure they’re correct.
   - Tested the notify-send command directly in the terminal, and it works 
   as expected.

*Question:* Is there anything I might be missing in the key binding 
configuration, or is there another way I could troubleshoot this? Any help 
would be appreciated!

Thank you!
