Problems with 2.4 and 2.5 with KVM/mouse

Problems with 2.4 and 2.5 with KVM/mouse

[Stephen Hemminger]

I have two machines on a KVM and when I switch between them the mouse
pointer goes wacky and causes random clicks. This has always been
somewhat of a problem when both machines were running 2.4 but there was
a workaround.  If I switched consoles (alt-F1, alt-F7) then the mouse
would restore back to correct behaviour. 

Now, on my test machine running 2.5 the mouse works until I do a KVM
machine swap. Then the 2.5 machine never clears up the mouse wackiness
and the only choice is to reboot. 

The mouse is a Logitech optical mouse with a wheel "Wheel mouse". The
mouseconfig is the same on both machines. The KVM is a Belkin four port.

Probably the simplest is to buy another mouse or switch to USB...

Have you tried restarting gpm?

No change when gpm is killed and restarted

I do remember that I have one board in my company that doesn't like KVMs 
at all (please don't ask for the brand, I'm offsite for a while and 
don't remember the type). All other boards connected to KVMs (different 
types) and running Linux 2.4 (various versions) work fine.
So I guess you do have a hardware (board) problem.
