I have XP and Fedora boxes in a belkin KVM. It works fine until I
switch to XP when I'm in Fedora (usually in GNOME) and then come back
to the Fedora box. Usually my mouse goes wild and I have to kill X. What can be done to correct this?
Let me guess, it is a wheel mouse? Those can work in two modes, old legacy PS/2 (no wheel) and new IMPS/2. Of course, if mouse is initialize in one mode, and your OS thinks it is in the other, you'd get what you described. My guess is that one OS initialized mouse into IMPS/2, and the other OS thinks the mouse is in old PS/2 mode.
Simply make sure you have configured mouse same in both Windows and Fedora.
BTW, some KVM switches (especially older ones, predating IMPS/2) have problems with this. I have one Belkin KVM switch that works fine, but my old one (Star-something, don't remember name anymore) had problems with it.
If all else fails, alternative is getting an older (probably no-wheel, don't know if there are any wheel mouses that are not IMPS/2) mouse that has only PS/2 mode (no support for IMPS/2).
