Erratic behaviour of kudzu and mouse

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; it-IT; rv:1.4.1) Gecko/20031030 Description of problem: when I start kudzu in a terminal window, my wheel mouse becomes erratic and I lose its control, many windows open in the graphical window. Furthermore, in the window, kudzu start in the window after a while and says that mouse has been removed, asking if I want to remove/keep modifications. I have to log out by Ctrl-Alt-Backspace Version-Release number of selected component (if applicable): kudzu 1.1.36-1 How reproducible: Always Steps to Reproduce: 1.Open a Terminal Window 2.become su 3.start kudzu Actual Results: 1) Lost of control of my Wheelmouse 2) Crazy behaviour of kudzu that start by itself 3) kudzu tries to remove my mouse from configuration Expected Results: Kudzu should start and let me probe my Soundcard (as in RedHat9 working till last night) Additional info: I get a message at shut-down saying that mouse service fails: I do not know if connected.
I switched to a text window by Ctrl-Alt-F1, I logged as a different user, I became su, I typed /usr/sbin/kudzu, but kudzu doesn't pop up and I go back to the command line, with no action. Very disappointing as I cannot setup old Soundblaster, that was fine in RedHat9 through kudzu.
kudzu really shouldn't be run under X, especially in the presence of a PS/2 mouse. You can run it with '-s' to skip the mouse probe.
I ran "kudzu -p" under X. Since the man page says "Print probe information to the screen, and do not actually configure or unconfigure any devices" about the -p option, I thought this was safe under X. It isn't. The PS/2 wheel mouse is correctly detected, but after running "kudzu -p" some ghost makes the mouse pointer jump around and click like crazy; it even tried to do a shutdown. I suggest a warning in the man page for the -p option, or a safer behaviour of "kudzu -p".
Here are some observations that I think are related. On my Compaq Armada M700 running RHEL 3 (kudzu-1.1.22-1.1) I have a built-in keypad and also a mouse that plugs into the PS/2 port. I don't know what type of mouse this external mouse is, but on it the words Dell by Microsoft are written and also PN X06-08477 Product ID 63618-OEM- Now if this mouse is plugged in while starting the computer I get the following entry into /etc/sysconfig/hwconf class: MOUSE bus: PSAUX detached: 0 device: psaux driver: msintellips/2 desc: "Generic PS/2 Wheel Mouse" And this is very wrong, neither theinternal nor the external mouse works. Now if the external mouse is _not_ plugged in while starting the computer the entry looks like this: class: MOUSE bus: PSAUX detached: 0 device: psaux driver: genericps/2 desc: "Generic Mouse (PS/2)" Now I the internal pad works fine, and if I now plug in the external mouse it works fine as well. So my conclusion is that kudzu for some reason misinterprets this mouse as intelimouse although it really is a generic PS/2
This is fixed with FC2 and later releases.
