Comment 117 for bug 257827

It was already proposed to add a checkbox for wether xfpm should control display brightness. That was over a year ago but it did not appear - developers could you please add this, along with a short description what problem it fixes? It's bad enough that display brightness setting cannot work with all computers correctly - having to dig into bug reports to correct this is inacceptable when there are actually that two xfconf settings that you can use to correct behaviour.
