Been through this before... upgraded from FC-1 to FC-3 - using a Belkin KVM things worked ok on FC-1 when switching back to FC-3, mouse is erratic and unusable. Doesn't help to switch to text console (Control-Alt-F2) and back to X. Doesn't help to add psmouse.proto=imps to grub boot. Anyone else seeing this on FC-32.6.9-1.681_FC3 ? Craig
