Re: KVM -> jumping mouse... still no solution?

[Rajendra P Mishra]

One quick solution I know of is to restart the gpm daemon,
(/etc/init.d/gpm  restart) that resets the mouse settings.
But this is not the correct way, there should be some way
where the driver automatically detects and resets the mouse.
