I have just brought this KVM switch:

But Im having major problems with getting the mouse to work under
FreeBSD. Even the keyboard does not work sometimes. This KVM switch
support for hotkey and also supports emulation on both mouse and
When I boot up my system and see the BIOS on the computer the
works just fine. Then when it continues to boot and comes to the
it still works. And the it starts to load the kernel. But then when
get to the login prompt the keyboard does not work.

And sometimes even thought I stay with the computer the hole boot
process I can't even use the keyboard. So I have to use ssh to
login to
the computer and make it reboot to regain the keyboard. I have also
tried to change the cables but I get the same results. And It works
no problems under Windows XP Pro.

The system that im using is FreeBSD 5.2.1-p9, at least on this system.

I  have also two other computers that Im running FreeBSD-stable on.
one of my FreeBSD-stable machines I have hade a working mouse under
Windows System (Xorg latest from ports).

But then I rebooted the system and when I started xdm, it found the
mouse but when I move it around It didn't move like it should. It
some seconds before it moved and it did not move like it should,
several ramdom cm/inches on the screen (Perhaps in the direction
that I
move the mouse im not sure). Its on usable in other words.

I have also tryied to use moused under FreeBSD but I get the same
fault/problem. I also have a problem if I do not have this machine
selected when I boot. Then when I switch to it when the boot of the
FreeBSD system has complete, The screen on the monitor just blinks.

Still the keyboard works because I can press two times Left Ctrl
then 1 to 4 to change the computer Im controlling. This I can not
with the FreeBSD 5.2.1-p9 system I can only see the screen but have
change the computer im controlling by pressing the button on the
switch box.

I have tried to remove the cables and put them back again. But that
not help, the only solution I can see is to reboot the system and
let it
boot with it selected. I have also booted up with the mouse
connected to the computer. Then when the system boot was completed
moved the mouse around to see that it did work. After that I
back the cable from the switch in to the computers mouse port. And
plugged the mouse back in the switch box, that did not work either.

I have also added flags to both psm0 and atkbd in my kernel config:

# atkbdc0 controls both the keyboard and the PS/2 mouse
device          atkbdc0 at isa? port IO_KBD
device          atkbd0  at atkbdc? irq 1 flags 0x0
device          psm0    at atkbdc? irq 12 flags 0x0

I have also tried with the flags set to 0x100 on both atkbd0 and
but that doesn't seem to make any diffrance. I have done this on my
FreeBSD 5.2.1-p9 box as well. I have also changed it in:


But I don't get it working correctly either by that.

Does anybody have a clue or have hade any similar problems and/or
could shine some light on this problem?

This all sounds familiar. I too had a lot of trouble
with a KVM switch. Actually, I tried two with the same
problem you are alluding to.

I came to the conclusion that the mouse will not work
through the KVM switch using FBSD, or at least I never
got it to.

Duh. All this newbie can add is that of all the dropped balls and blind alleys I have experienced wrestling with FreeBSD, problems with my four port KVM switch have not been among them. Make of said switch is lost in the mists of time - it is whatever CompUSA sells. I have a Logitech track ball; It and the keyboard have functioned well through various permutations of 5.1, 5.2, and 4.10, native and under KDE. -LenZ-

What you are saying In short is that you did not experince any problems?

I have two computers that are both running 5.2.1

I have connected a mouse directly to each computer.
I still had to shutdown both computers and connect
the cables for the monitor and keyboard from each to
the KVM. I also connected and old mouse to the output
of the KVM.

With all this connected, I then powered up both computers. All seems to
work fine with the inconvenience of having to use 2 meese. I seldom have to
go into one
fo the computers, so I can live with it.

This is probably not the answer you were looking for
but you were also looking for others who had problems.

Best of Luck
