Modify xfce4-power-manager handle brightness keys on different 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. 

It seems as though XF86MonBrightnessUp/Down is also set to to the appletb_backlight 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.
