Yes but how is the checkbox supposed to work? There's no point in xfpm
having the checkbox if it doesn't work. Is it possible for pm-utils to
co-exist with other power managers? How do other desktop power
managers override/control pm-utils? Should upower have the depend on
pm-utils removed, and then add a conflict between pm-utils and
xfce-power-manager?
