imps2 mouse doesn't work with KVM switch
 

I have a Belkin KVM switch and I got it all setup and everything and everything worked fine. A few days later when I restarted one of the computers, the keyboard worked fine but then when I typed 'startx' I couldn't move the mouse. I restarted the computer and tried again and again and again with no luck. This happened on the other computer, but the mouse always worked after two or so restarts. I have Slackware 9.1 and running KDE

I can't say this will solve the problem, but I used a Belkin to swtich between Linux and Windows, and the mouse would always successfully go from "A" to "B", but if I then tried to go back to "A", it hung just as you described, regardless of which OS I started with.

Solved the problem by replacing the Belkin with a Trendnet TK-401R, which works flawlessly. -- J.W.

heh damnit lol I can't get a new one I'm poor :P

Try a different mouse.... Yeah, same KVM and same system, but different mice types (both the XFree config type and the actual hardware) respond differently to being switched.

Well, maybe this is a signal that it's time for you to dump Windows and go 100% with Linux :) -- J.W.

I'm gettin' close to that

Check if you are using a PS/2 -> USB converter
 

All of my KVM problems went away when I noticed that the actual mouse I was using was connected to the
KVM through one of those PS/2 (round plug) to USB (rectangle plug) converters.

I found another mouse that didn't need the converter, but still has the wheel and everything works great.

For me the IMPS/2 didn't matter and getting rid of the scroll wheel in XF86Config didn't help but getting that converter out of the way made everything work like magic.
