Redhat 9 mouse lost problem when using input switch


By Rachel007 - usenet poster


I have an input switch so i can use two
machines with the same mouse/keyboard/monitor.
Unfortunately in redhat 9, if u switch from a machine
and back again, u have lost contact with the mouse
and u have to restart x, to get the mouse back.
I am using a ps/2 standard mouse.
This is probably a xfree 4.3 problem but I
cant find a way to fix it?
(this problem did not exist in redhat 8.0)

anyone knoes a fix?
I have the same problem.

i now found the fix to my own problem on the net:
add the kernel option psaux-reconnect.
so update /etc/grub.conf so there is a line similar to:
kernel /boot/vmlinuz-2.4.20-8 ro root=LABEL=/ hdc=ide-scsi psaux-reconnect

xfree86 4.3 does not handle reconnects anymore like 4.2 did.
instead it now leaves that to the kernel.

btw complete waste of time in this thread when people talk about their
fancy inputswitches (and where you can buy them).
i said it worked in redhat 8 but not redhat 9.
i am very happy with my low end $20 manual inputswitch
and plan to keep it

Thanks for the tip Kalle, very helpful.

By the way I echo your comment about where to purchase a KVM,
especially so as I am *not* in the USA. It's a big wide world out
there!

I also have a mix of machines including RH 9.0. My KVM is the Ultraview
from Rose Electronics (high end).  I also use IOGEAR's Miniview 4 port
KVMs but haven't tested with RH 9.0.  A 4 port Miniview, including
cables (2 3 foot and 2 6 foot) can be purchased online from CompUSA for
approximately $ 110 delivered!

Sounds really strange, I run XF86 4.3 on my machine and  I don't have this
problem when switching between the linux machine and my MorphOS machine.

You could post about this at comp.os.linux.x (this is a XFree86/X11 newsgroup).

Probably depends on the switch.  Seems like some switches actually
provide feedback to the machine that you are NOT using at the moment,
or something like that.

Anyway, I run a KVM here on the RH 7.3 server and my "development and
testing" machine. Currently running RH 9.0.   Works fine here.

Exactly the same with me. Logitech 3-button wheel mouse with PS/2
connector. I have a mechanical KVM and on R.H. 8 this was fine. I have
just gone to v9 and it's really annoying. Not only does X have a sulk
but alternate times I boot kudzu adds/deletes the mouse from the
configuration. The other machine sharing the KVM is a Windows box, but
I don't really think that would be an issue.

The Logitech mouse part number is 851393-0000, it's an OEM item and I
can find very little information about it.

Any help is gratefully received.

It definitely depends on the switch. In our cubicles, we use
consumer-grade Belkin two-port switches (~$100 or less at Fry's) and
they have problems with keyboard lockup on more finnicky OS'es --
particularly Windows NT boxes.

In the development lab, we use more expensive enterprise-class KVM
switches from Raritan -- a 2-port can go for almost $300. But they
never lock up, and never require a reboot. Thus, the extra $200 is
definitely worth it in the lab and data center.
