I agree with this, I posted a similar analysis a month or so ago. In
fact, as of a couple of days ago I began working around the problem in
KDE by shutting down guidance-power-manager and running gnome-power-manager.

If these analyses are correct, then I'm at a loss as to how it seems to
be overlooked that Kubuntu appears to have no facility for handling
brightness key events, and how the actual brightness-changing
functionality got removed from /etc/acpi/events before
guidance-power-manager (or whatever) grew a replacement for it.

Agreed, I'd like to repeat my opinion that having to be logged into your
desktop environment to change the brightness of your LCD using
*dedicated hardware keys* is less than ideal.
