X server log
XF86Config file has:
Option "Protocol" "MouseManPlusPS/2"
Option "Device" "/dev/input/mice"
Option "Buttons" "7"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "4"
#Option "EmulateWheelInertia" "50"
Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"
#Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "no"
This configuration worked with RedHat 9's XFree86 packages (with
appropriate device string).
The wheel button is absorbed by the mouse driver, so you can not use
that button for other purposes. Your config section in comment 2 sets
button 4 as the wheel button, so this would explain it.
I didn't get the expected results correct. Pressing button 4 by itself
should not report any event, as you say. Pressing it and moving the
track ball should report buttons 4, 5, 6, or 7, depending on
direction, as given by the X and Y axis mappings.
It should not be reporting button 1, though.
I also agree with Kristian above for this issue. It seems to
be misconfiguration resulting in unexpected behaviour. Your best
bet is to subscribe to the email@example.com mailing list and
ask for help configuring the mouse to have the behaviour you
expect. That way it will be clear what is wrong with your
configuration, or wether there is a legitimate bug being triggered
If it does turn out there is a bug being triggered, then please
file a bug report in the X.org bugzilla and cut and paste the
bug URL here and we will track the issue in their bugzilla
Setting status to "NOTABUG".
The configuration given above worked in RH9 (and previous versions,
don't know how far back exactly: from when EmulateWheel and
XAxisMapping was added to X) and it works in Mandrake 9.2. I'll look
into reporting it to Xorg.
