The older Intellimouse protocol uses the full fourth byte for wheel data. Your KVM doesn't understand the Explorer part of the protocol (which the PS2/USB Intellimouse supports), and while it allows the Linux kernel to detect and set up the extended protocol, it cannot pass it back, passing back the older version, where the bits depend on the sign of the mouse wheel rotation. Thus, with older systems you'll experience no problems. Without the KVM you won't experience any either. But with a new Linux, old KVM and a new mouse, spurious button events will appear when the wheel changes direction. The only solution (since the KVM cannot be detected by software) is to force the kernel to use the older Intellimouse mode of your mouse. To do that, use "psmouse.proto=imps" on the kernel command line (in /boot/grub/menu.lst). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
