Re: Restarting the mouse after KVM switch

[David G. Miller (aka DaveAtFraud)]

I've had a similar problem and I think the problem has more to do with the
mouse and/or the kvm.  I typically see the problem when I either traverse
a system on the kvm that isn't in graphical mode or a port on the kvm that
doesn't have a system attached.  Generally, I can get the mouse back under
Linux by switching to a different virtual console (CTRL-ALT-Fn where n is
not 1 or 7) and restarting gpm from the command line.  Sometime I have to
unplug and then plug the mouse back into the kvm before restarting gpm.

This problem was absent when I was using a non-optical mouse.  It only 
showed up as I have replaced my mice with optical versions.

I think that you are right- now that I am very cafeful not to move the
switch over to an empty position (and VERY careful not to let the
mouse move while I switch), I have not yet had any problems. I have
not yet added the kernel parameters.

Now if I could just get my rat to behave as well as the mouse (yes, we
have a pet rat)...

C.F,
Thanks for the suggestion. Swithcing between terminals has not worked
for me. So far, only restarting X has been useful!

The CAB4WAY that you suggest appears to be a printer switcher.

Thanks, CK! Now that I've learned to be careful about moving the mouse
when switching machines, the problems have just about disappeared! But
your thinking about sending a switch is very generous.

Just as an aside, I've used both Linksys and IOmega switches with a
lot of success.  I've got a four-way Linksys that switches between
three FC machines and a Mac Mini and it's never glitched--and that's
even when the cat's been batting the mouse around (yes, my cat finds
even computer mice facinating...she's a geek).

Rick,
You cat should meet our rat! She thinks that plastic mice are the most
common type... But she also thinks that their 'tails' are tasty, which
encouraged us to switch recently to the cordless type.
