FC4 - KVM mouse needing reset

[Craig Preston]

This is a problem I had as well, not just with Fedora but other Linux
Distros as well. I believe it is to do with the fact you are using (I
assume) a PS/2 mouse. The cheapo belkin will loose connectivity for a
second with the machine and because PS/2 isn't supposed to be plugged in
while a machine is on, it goes haywire. I haven't seem the problem occur
with USB switches as USB is hot pluggable and seems to work fine.

Anyway, I have never been able to find a fix that worked for me and as I
am just switching between two machines I just plugged in a second mouse.

Cheers,

Craig

indeed this is sage advice.

I live without mouse wheel cuz I am too cheap I guess to switch kvm
switches.

Belkin KVM switches just don't work well with RHEL/Fedora and haven't
for a long time.
