breaks KDE and any other software that assumes setting 0 will induce the
minimum brightness. Maybe it would make more sense to set the brightness le=
vel
to "1" if userspace requests brightness level "0" so pr=
ograms still function
correctly.

If desired the call could still return false to indicate it was out of boun=
ds,
but still lower brightness.
