Making Mouse Wheels Work w/ a KVM? 85
Elvii asks: "My mouse wheel doesn't want to work through my KVM. It doesn't work in X11 under Linux (Debian 3.0, kernel 2.4.20), but it works in Windows on same machine, through same KVM, so that tells me it's a protocol or driver issue , which is beyond me. I have no other OS's to test on, although I read online that FreeBSD can handle the mouse wheel in this type of setup. When I set the mouse type to IMPS/2, it just twitches in corner and randomly clicks. Anyone know if it's a kernel issue or an X11 issue? I've googled and found nothing of real use there - just that some KVMs work and some don't. Plain PS/2 works but I want my wheel too." The kicker is that when the mouse is plugged directly to the machine, the mouse wheel works just fine! Has anyone else experienced the problem? What did you do to fix it?

I always wondered why two-input monitors didn't also include keyboard and mouse switches. It only seems to make sense, that's all. Why would you want to switch monitors, but not the keyboard?

I got a cheapo 4 port kvm switch (although it seems to work fine) from newegg.com. It was about $50 and the cables were around $10 each. Each $10 cable has a separate cable for mouse, keyboard and video tied together to keep things a little neater.
So for around $90 (under $100) you've got the switch and cables for 4 PCs, just supply a mouse, keyboard, monitor and the PCs.

Mouse reset... (Score:3, Interesting)
Every so often a wheel mouse under Linux seems to hang (i.e., not do anything) under RH 8 and 9. This isn't the system, it is some kind of confusion caused by the mouse. Switching virtual consoles away from X then back again seems to clean things up wonderfully.
What I would love to know is where is the mouse reset is being generated, i.e. is this X, /dev/mouse or what? Clearly Win either is sending out a periodic mouse reset or

The point you're missing is that none of the links give an actual solution to the problem. The three best solutions so far (from my research) are:
And while the question is phrased as if it should be posted to comp.os.linux.* or somesuch, the underlying issue is valid. The Windows mouse driver is able to compensate for shortcomings in KVMs, while the various open source drivers are not, despite theories that this could be done in the X mouse drivers. There is no solution and no good workaround, so hopefully publicity will inspire someone to find the solution.

I've got 3 Belkin KVM's with the same problem (Score:5, Informative)
There are two things to check, first turn off gpm. It's never done anything but give me grief in all the time I've ever seen turned on. I know that this will solve problems on several different KVM's I have. I know on one of the KVM's, it fixed all my problems so I could use the IMPS driver without doing the second fix.
Second, is that something is completely screwed about XFree86 of handling the PS2 mice, you can switch to a serial mouse, but no wheel then. The way to fix the problem, is to get XFree86 to resync/reset with the mouse. After switching from once machine to the next, immediately switch to a virtual console, then back to X, and the PS2 drivers will resync/reset/"do the magic to make it go". I've got no idea what the problem is, or why switching consoles works, but on the various Belkin Switches I've seen that is the fix that works best.

Did you bother with the Linksys support site? Perhaps this [linksys.com] is the problem you are having.
The Linksys product description says, "Because they donâ(TM)t use software, the ProConnect Compact KVM Switches are compatible with all major desktop and note-book computers." One might read into that statement that the switch is not altering the electrical signals and that the switch is compatible with all mice. Sadly, that appears not to be the case and although a known limitation they don't mention it in the description. I'd send it back and buy from a company that makes KVM switches that work properly.

The protocols are entirely different, and the PS/2 keyboard protocol is older, simpler, and better understood. It's been a long time since they made any substantial changes to it.
Nonetheless, few KVMs support the entire PS/2 keyboard protocol. I have tried four different KVMs, all different manufacturers, and not ONE of them can properly support the keyboard of an IBM PS/2 95 running OS/2. You type enter and
