Yes I have. And No there's nothing binded to Fn+F(4) and Fn+F(5) key
combinations. And I don't think this is xfce related issue as I have
sual boot setup with another OS being Debian with xfce in which
brightness control works just fine.

So I'm afraid but to infer that this is FreeBSD specific issue.

I think this is FreeBSD specific issue as my another setup Debian+XFCE
is doing just fine with brightness control.
