Modify xfce4-power-manager to use different display device

Hello,

I'm on a macbook pro using arch linux, through t2linux.

When using xfce4-power-manager to handle display brightness keys, it changes the brightness value in appletb_backlight, which I do not want. I would like it to change the brightness value of the acpi_video0 device.

I am currently changing the brightness through my window manager i3 through executing a brightnessctl call on the device, which is not ideal. I prefer to use xfce4-power-manager to handle the brightness keys if possible.

How can I change this?

Thank you
