I've been having the same problem and tried a lot to fix it. Today however for some reason my X-server didn't want to play nice, forcing me to remove /etc/X11/xorg.conf. Additionally I set my default-desktop-manager to xfd (from gdm3). One of these steps fixed my problem. Therefore I think that it's either a result of both gdm and xdm (for me) that tried to resolve key-bindings, or X-server that assumed some bad things about the backlight control.
Hope this helps, if you haven't found a solution already.
