Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Belkin switch and my solution was to just use 2 mice. (one dedicated to my linux box) I noticed it when I went from Redhat 7.3 to 9 and the problem has been there ever since. Have co-workers with SuSE and it happens to them too.
Some options we have found are adding 'psmouse.resetafter=1' or 'psmouse.proto=bare' to your Grub or LILO load lines. Sometimes they work other times they don't.
I have used a Belkin 4 port KVM with the following combinations without a problem.
Windows 98, Windows 2000 and RH8.
Windows XP, Fedora 1 and RH8
I recently tried the following upgrade.
XP, Fedora1 and Fedora2.
When I would switch from FC2 and return, the mouse has always gone to the Bahamas and I must reboot the FC2 platform.
I went to the following configuration,
XP, FC1 and FC1.
Everything works fine. which indicates to me the problem is in FC2.
Any suggestions? I would love to upgrade to FC2 on both Linux platforms. If I can ever locate the proper software, eg; something to handle my Kodak photos, etc, I would like to upgrade the XP box to FC2.
I and others at my workplace have had problems with mice and KVM switches (never with displays or keyboards, just mice). As others have suggested, I just use separate mice and all is well. Apparently this happens for some people but no others. I might check the model of my KVM switch tomorrow and see if it matches any of the ones here.
I've been successfully using a Zonet 4 port (ps/2) KVM with windows and SuSE 8.1 for a while. I have really loved the kvm and had no trouble at all until upgrading to SuSE 9.1, in which the mouse wigs out after switching back into it. This behavior is consistent on two different computers (both pentium 4's, but with different chipsets and motherboard manufacturers).
So perhaps it is kvm dependent, but it definitely is connected to SuSE 9.1.
I have the same problem with my KVM switch causing the mouse to go crazy. I have not found a "solution" but I do have a work-around. When I switch back to the linux computer, I do not touch the mouse until after I have done these key sequences:
This allows the mouse to reset. I'd like a better solution too.
I have had to use this with RH 7.3, RH 9, Mandrake, and Fedora. My KVM is a Belkin 4 port OmniView PS/2. MS Windows comupters never have the problem with the KVM. (just a fact, not saying windows is better)
We had this same issue with the Belkin KVM switches. We got Linksys switches now and the problem went away. Actually we have one, and we ordered this one and if it doesn't work I'll come back and let you know. I assume it has the correct protocol to avoid the crazy mouse issue. The one we are using that works for certain has an external power plug and is a couple of years old, but the same shape as this one:
I thought it was just my system. Running Redhat Enterprise WS and Belkin 2 port KVM that I just bought (wish I had checked here first!). Running XP on the other machine. When I switch to the RH box it says "1: Analog Input. Cannot display this video mode". Guess I need to try their tech support before I return it and get a different brand. By the way I also had problems with a Cables To Go 2 port USB KVM. Both computers keyboards would lock up. Could have been the USB keyboard, but I never had the problem when it was directly connected to either machine.
Just figured this out! had to run X reconfig program to get it to recognize the monitor. Boy do I feel stupid. Anyway I learned something. The command in RH E WS is "redhat-config-xfree86 --reconfig" once you are in a new screen sesson (ctrl-alt-F2) sign in as root and run "init 3".
I use a Belkin F1D094 4 port KVM which worked fine between 2 mandrake boxes. However I have since upgraded to mandrake 10 and it just goes beserk. I now have to use 2 mice which is a pain. If it ain't broke, why do they have to fix it?
Distribution: RH, FC 1-6, F 7-21, Debian, LinuxPPC, Knoppix, Ubuntu, Yellow Dog
Good point. I have an Avocent 4-port KVM between a linux box and a Windows box. The linux box works fine with the connected hardware, but the Windows box requires a separate mouse. Terrible. On a side note, does anybody know of a KVM switch that accepts USB mouse and/or keyboard?
I cannot use my i386 PC with Linux OS (FC2 then FC3; on two different PCs) with my Belkin KVM model F1DB104P. Each time I leave the Linux PC, then return, the mouse become unstable, and jumps all over the screen, selecting everything it touches. (There is also a prob if I boot the Linux PC, then move to it.)
On cycling through the Windows PCs, it works fine. When the current Lin PC was a Windows PC, it worked OK.
I had this same problem when using a Belkin 2 port -- I could always make *one* switch from one OS to the other, but could never go back to the original OS. Didn't make any difference whether I started in Linux or Windows, I could only switch once.
Problem solved by replacing the Belkin 2 port with a Trendnet 4 port, which is what I'm using now and would recommend. (Model = TK-401R) I've got a few machines, and can happily toggle between my dual boot XP/Linux machines and my 100% Linux boxen. -- J.W.
I happened to recall a not-very-great wireless MS mouse I had lying around, so I removed the KVM mouse OS/2 plug ---replacing it with the USB plug of the wireless one. It works fine; meanwhile the extra mouse, being wireless is not much of a problem.
