My Ubuntu skills are very limited.  However, as long as a user is
running either GNOME or KDE, things should just work.  The mixer
applications pick up the volume up and down events.

Handling brightness events for ThinkPads is another story.  The events
will reach user space but user space is not ought to do anything as they
are handled in hardware (c.f. [1]).  But thinkpad-keys did not do
anything about this anyway.
