Angry Mouse does not work through KVM


OK, I have a compaq evo n610c notebook running SuSE 9.2 plugged into a 4 port starview KVM. The mouse doesn't work, it's not recognized. If I cat /dev/input/mice or /dev/psaux I get nothing. However if I plug the mouse directly into my notbook I get

evdev_connect: evdev cdffcd80 handle cdffcd9c name event1
input: PS2++ Logitech MX Mouse on isa0060/serio1

in my dmesg. And it works!, but the KVM stops it... however, I have a SuSE 8.2 box that is plugged into the KVM, and the mouse works on /dev/psaux

The mouse is a logitech mx700 wireless that uses a usb to ps/2 adapter to plug into the KVM, and the KVM interfaces with the computers via ps/2.

Please help, I am losing my mind over this. (I tested the cables... they are functional)

My experience with a KVM switch has been a pain at times.

Sometimes the KVM installation instructions will tell you to power everything off. Plug everything in. Turn on the KVM switch. Turn on the computers. And don't hot-swap any cables. Always power down.

Just before Christmas I was doing some work on 2 servers connected to the same KVM switch and I guess I was moving the mouse when I pushed the switch button and the KVM stopped working. I powered everything off. Powered up the KVM. Powered up the servers. Voila! The KVM started working again.

Your mileage may vary.

Thanks for the quick reply.... I though this was the problem as well (I too have had that same headache ) but I don't think it's the order of powering on or off or resetting the KVM because the notebook is a dual boot, and in Windows 2000 it recognizes the mouse.

You might find some help here.

Protocol "Auto" seemed to be a fix for a mouse issue.

Here's some more info:

Thanks for your reply, but this was unhelpful. My notebook running SuSE 9.2 never recognizes my mouse when plugged through the KVM. I tried reboots, and different KVM methods. All do not work, it's not like other cases where the mouse works, but when I switch to another computer, and back it stop working. IT'S NOTHING LIKE THAT!! It is never recognized, I tried playing with the hotplug settings without luck... anyone else?

Have you tried connecting a mouse directly and see if it works. If it does not then I believe you need to edit your X confiuration file. Look at this post for pointers. http://www.linuxquestions.org/questi...light=ps+mouse You need to setup a 2nd mouse option.

Hi,

It does work if you plug the mouse directly into the notebook. Just not through the KVM

I assume you are still using the usb to ps2 adapter to plug into the notebook. You are not using straight usb here. Are you using a splitter for keyboard/mouse to connect to notebook. Most notebooks only have one port. You can connect either a keyboard or mouse or both with a splitter.

A lot people that uses wireless mouse should not use KVM switches. The reason for this is that KVM switches have to emulate a mouse that is connected. If the KVM does not have support for a certain mouse protocol that a wireless mouse uses, it will not work. Some KVM switches gets power from the PS/2 connector. Because of this you need atleast one computer powering the first port. Use a wired PS/2 mouse instead of a wireless mouse. USB to PS/2 converter has nothing to do with this problem.

I have a Miniview 4 port IOGEAR KVM switch. The mouse and keyboard that I use is a Logitech MX300 and a Microsoft Natural. The mouse has a USB to PS/2 connector that works with out any problems. The KVM switch is connected to three computers. I have no problems when switching from computer to computer and no problems disconnecting the mouse, keyboard, and monitor while other computers are running.

Are you serious that this is your answer? I mean I really appreciate the helps from these forums as I couldn't figure a lot of this out on my own, but if you are not at least going to read what the problem is, at least provide a solution for something... I mean not only does your answer not address my problem, it's just a statement and provided a solution for nothing!

Posts like this seriously degrade the integrity of linuxquestions.org

Thanks Electro,

I have tried using a wired mouse and it doesn't seem to work still, and my SuSE 8.2 desktop sees the wireless mouse fine through the KVM... I can switch off, and back on to the desktop and the mouse always works!! It's just my notebook running SuSE 9.2

Do you think that a USB KVM will help?
