Duh.  All this newbie can add is that of all the dropped balls
and blind alleys I have experienced wrestling with FreeBSD,
problems with my four port KVM switch have not been among
them. Make of said switch is lost in the mists of time - it is
whatever CompUSA sells.  I have a Logitech track ball;
It and the keyboard have functioned well through various
permutations of 5.1, 5.2, and 4.10, native and under KDE.
