I'm relatively new to Arch Linux, having just set it up on my Thinkpad using MangoWC. I'm trying to get my brightness and volume buttons to work properly. I thought the easiest way would be to set up a script in my Mango config file. Currently, I've configured it like this:
```
bind=XF86MonBrightnessUp,spawn,/home/shakaka/.myscripts/bright.sh
```
The `bright.sh` script contains:
```
#!/usr/bin/env bash
brightnessctl set +5%
```
I have a similar setup for reducing brightness. Despite rebooting and reloading my Mango config, the buttons still don't work. Any help would be greatly appreciated!

Have you checked if `brightnessctl` is installed and if it works fine when executed from the terminal? Also, try running the `bright.sh` script directly in the terminal to see if it works that way. As a troubleshooting step, set your keybind to spawn a different command, like opening a text editor, to see if the key event is being recognized at all. Since your script runs only one command, you could simplify it by directly assigning:
```
bind=XF86MonBrightnessUp,spawn,brightnessctl set +5%
```
Yes, I confirmed that `brightnessctl` is installed, and the script works when I run it directly in the terminal. I tried changing the keybind to launch foot, but nothing happens there either. For reference, I also have wev installed, and it recognizes the brightness keys correctly as XF86MonBrightnessUp and XF86MonBrightnessDown.
