Title:
  scroll wheel events not available to X under synaptics driver

Status in xorg package in Ubuntu:
  Expired

Bug description:
  Binary package hint: xorg-driver-synaptics

  under breezy and dapper, but not some other older configurations
  (mandriva), my laptop's hardware scroll-wheel (also the middle button,
  button 2) is not accessible as X events.

  I have an ALPS touchpad on a Toshiba Satellite 2410.

  Using the Synaptic driver, I get nice features on the touchpad, including a software-run scrolling on the right side of the touchpad,
  but the scroll-wheel (a hardware wheel that also works as mouse button 2) does nothing.

  When I run xev, it notices button 2 being pressed but gives no notice
  of it being scrolled (in particular, there is no mapping of the up and
  down rotation of the scroll wheel to buttons 4 and 5).

  I have the default entry in xorg.conf:

  Section "InputDevice"
          Identifier      "Synaptics Touchpad"
          Driver          "synaptics"
          Option          "SendCoreEvents"        "true"
          Option          "Device"                "/dev/psaux"
          Option          "Protocol"              "auto-dev"
          Option          "HorizScrollDelta"      "0"
  EndSection

  
  These buttons should be available to X somehow.
  Ideally, the xorg.conf line
          Option          "ZAxisMapping"          "4 5"
  should then be useful.
