Before Linux support for acpi_osi("Windows 2012") (and when booting with acpi_osi="!Windows 2012"), brightness keys were handled by the kernel just fine, whether in console, in the display manager or in my desktop environment (Xfce). xfce4-power-manager just needs to be told that the brightness keys are already handled and it doesn't need to do anything.
How do you tell xfce4-power-manager that?
xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/change-brightness-on-key-events -s false
You might have to create the key before. See https://bugzilla.xfce.org/show_bug.cgi?id=7541 for more information.
