Hi All,
Something that just has been annoying the daylights out of me for the past 9 months with no resolution in site. I've got a Hawking HKS 104 4 port KVM connecting my Linux workstation, 2 servers, and my wife's windows workstation to one monitor, mouse, and keyboard.
No matter how I toggle back and forth whether by keyboard or directly on the device once I come back to the linux desktop scroll wheel on mouse no longer functions. Except for a brief time while running CentOS 4.4 it's always been this way. I've googled until there were just no more places left on the internet and searched through CentOS archives until I'd read everything from balls to bones without finding any helpful information.
Does anyone have any ideas or thoughts on how a fella might resolve this? When I restart the machine (Linux) the scroll mouse works normally, that is until I toggle to the windows machine and back again or to one of the servers and back again. Then the mouse functions like a two button mouse not having a scroll wheel. I appear to be stuck in KVM hell with this.

I have problems, but not yours.
1. Replug the mouse? 2. Replug everything in the KVM? Sometimes mine (Laser junk) requires this. 3. Different mouse?

I've seen that before. I had to change my KVM. The newer Belkin and Trendnet work. If you get a new one make sure it says that it's compatible with Linux or Unix, I had the same problem with Solaris 10 but not anymore...

Hi
this was my nightmare for about few days. I was and still am running hdd install of knoppix 4.02 on main pc and second testing pc with (win xp, debian, knoppix, kbuntu,ubuntu, freebsd and now centos :o). Using Belkin KVM for two computers.
The only solution i found was to put " psmouse.proto=imps "to grub. It is also working when booting knoppix live cd as cheat code. But did not succed on *buntu. I did not test it on Centos, as i am only using terminal.
good luck

Hi Pavel,
That sounds interesting, but I'm still wondering what happens at boot time that makes the mouse function properly and gets broken when I toggle the KVM?

Hi Mark
Mouse(genius netscrool + eye) and keyboard are both ps/2. If you remember old mouses had a button on bottom for two options: mouse and x11 (or something like that). So i believe that win want to use IMPS.
I also found many info when using google : KVM linux Windows mouse problem
But to be honest, i believe the mouse was also crazy when switching between two linux systems.

I've had the same problem with Belkin with PS/2 connections (erratic mouse movements after switching from Windows). But after a change to Aten KVM with USB kbd/mouse everything works as expected when switching between Windows and Linux boxes and with working scoll wheel on the mouse.

yeah... the overall concensus is that a different KVM and possibly a different mouse/keyboard will fix the problem, but since that is very unlikely to happen I'm going to have to find a software/OS solution. That's the biggest reason I'm now looking at what happens at boot time to allow the mouse to work correctly and then breaks and doesn't function after a KVM toggle back from Windows.

Either try 'chkconfig gpm off; service gpm stop', or (after every KVM toggle) try running 'service gpm restart'.
If GPM isn't chkconfig'd on in the first place, also try that (followed by the restart after every KVM toggle).
This is a little bit of a shot in the dark, but I've found in the past (with older versions of RH/CentOS, but still) that when a PS/2 mouse is unplugged and then plugged back in, GPM has to be kicked before the mouse will respond properly, even if the console is running X11 at the time.

Different KVm's handle the switching and emulation differently, and I have found that it seems to be more of a bios issue than a software issue. I had an old server running Windows 2000 that behaved badly on the KVM. When the system was retired from Windows use and re-christened with Linux, the problem stayed. It has an Intel STL2 motherboard, so there won't be any bios updates for it.
