XF86Config file has: Section "InputDevice" Identifier "Mouse0" Driver "mouse" 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" EndSection 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 xorg@freedesktop.org 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 here. 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 centrally. 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.
