KVM Switch & Erratic Mouse Behaviour

This only applies to wheeled mice - switching to other boxes on a 4 port KVM switch and back to your Linux box results in erratic mouse behaviour.

Here's the solution (for Mandrake - probably applies to other distros too) - your wheel will stop working, but at least you'll be able to switch via KVM without your mouse going crazy.

Edt /etc/X11/XF86Config-4

Go to the "Section 'Input Device' "

Change the IMPS/2 in Option "Protocol" "IMPS/2" to "PS/2"

Restart X (ctrl-atl-backspace)
