  The KVM causes problems when you use a wheel mouse and tell Linux it
is a wheel mouse. It tries to emulate the mouse when it isn't connected
to a computer for input. The mouse it emulates is a non-wheel mouse, and
hence causes the problem. So you can either reconfigure the mouse on the
Linux box to non-wheel, or replace the KVM. There are a variety of
temporary workarounds, but no solution I have found.

  I own a Belkin 4port ps/2 kvm and ended up replacing it with a Iogear
Miniview SE 4port ps/2 kvm. The Iogear does the emulation properly, at
least for the wheel mice. As for more complex mice with extra button I
haven't dared.
