Re: KVMs and the 2.6 Kernel

I've posted before about some mouse problems with the 2.6 kernel. I've
finally tracked it down to the KVM. Right now I'm using a 4 port KVM
that was never any problem until the 2.6 kernel. Now that I know that
the flakey mouse behavior I'm experiencing is from the KVM, I want to
replace it. I have heard about people using KVMs with the newer
kernels without problems. (I'm currently using Sid with the 2.6.15
kernel, but may be using Ubuntu on a few when Dapper Drake comes out.)
I'm using a Logitech keyboard/mouse combo, both cordless. The mouse is
optical and I do use the scroll wheel a lot (that's where the problem
is). I don't know if that makes a difference, but it might be worth
mentioning.
I am hoping to move to an 8 port KVM. I usually work with some of my
systems through ssh, but it would be nice to be able to have 8 ports so
I can switch over when needed. If necessary, though, I can use a 4
port. If possible, I'd like to find one with an on screen display. It
isn't necessary, but it would be helpful. A quick change time would be
helpful, as well. While the 2-6 seconds my current KVM doesn't sound
like much, when I'm testing software and have to switch back and forth,
it can be a pain.
If anyone is using KVMs that work well with the 2.6 kernel, I'd like to
hear what works, what kind of mouse and keyboard you're using and if
there are any problems. I've seen some good ones on New Egg, with
reviews that said they've used Linux, but the kernel version is never
mentioned.
Hi Hal,
I'm using Belkin Omni, now into its 5th year. It's had its fair share of
problems, but with the latest upgrade of udev, I think it's OK again.
The worst problem when switching to my linux box (testing on 2.6.12) was
that I would have to pull the mouse cable out of the KVM and push it
back in, then linux would register it again.
Now it does it, but there's a 1 or 2 second pause which to me is
acceptable. On windows there's no pause.
Unfortunately the Belkin Omnicube I bought was one of the last models
they sold without flashable ROM. I think if it had flashable ROM, I
could upgrade the ROM and get rid of the problem.
So there you go. I'm happy, but you might not be. I'd say, make sure you
can return the KVM you buy in case it doesn't meet your requirements,
and try another.
Adam
