LinuxQuestions.org - ALPS Glidepoint + scrollwheel - getting the scroll wheel to work.

hey guys.

ive got an ALPS Glidepoint, the mousepad works just fine, but this particular model of laptop also has an additional scroll wheel right below the mousebad buttons that i cant seem to get working.

here are the xorg.conf settings.

Code:

# suggested settings from http://gentoo-wiki.com/

Section "InputDevice"

  Identifier "Synaptics"

  Driver "synaptics"

  Option "SendCoreEvents"            "yes"

  Option "Protocol"                  "auto-dev"

  Option "CircScrollDelta"            "0.1"

  Option "CircScrollTrigger"          "7"

  Option "TapButton1"                "1"

  Option "TapButton2"                "2"

  Option "TapButton3"                "3"

  Option "LockedDrops"                "1"

 EndSection

you can see here that i have turned of the vertial scroll sidebar, i just find it annoying.

heres the out from /proc/bus/input/devices.

Code:

I: Bus=0011 Vendor=0002 Product=0008 Version=6324

N: Name="AlpsPS/2 ALPS GlidePoint"

P: Phys=isa0060/serio4/input0

H: Handlers=mouse1 event2

B: EV=f

B: KEY=420 0 70000 0 0 0 0 0 0 0 0

B: REL=103

B: ABS=1000003

as i write this, im thinking that this is as simple as finding out what mouse button the scroll wheel uses, im just not sure how to do this. would the best method be trial and error? anyone know of another event tracker that i could use? i know that xev doesnt work for this, ive already tried.
