Copy & paste from dupe:

My Ubuntu Intrepid installation recognizes correctly trackpoint, but sets option "EmulateWheelButton" to non-existing button 4:

(II) config/hal: Adding input device TPPS/2 IBM TrackPoint
(**) TPPS/2 IBM TrackPoint: always reports core events
(**) TPPS/2 IBM TrackPoint: Device: "/dev/input/event10"
(II) TPPS/2 IBM TrackPoint: Found x and y relative axes
(II) TPPS/2 IBM TrackPoint: Found 3 mouse buttons
(II) TPPS/2 IBM TrackPoint: Configuring as mouse
(II) XINPUT: Adding extended input device "TPPS/2 IBM TrackPoint" (type: MOUSE)
(**) TPPS/2 IBM TrackPoint: YAxisMapping: buttons 4 and 5
(**) TPPS/2 IBM TrackPoint: EmulateWheelButton: 4, EmulateWheelInertia: 10, EmulateWheelTimeout: 200

It can be easily corrected by this piece of xml in /etc/hal/fdi/policy/:

<?xml version="1.0" encoding="UTF-8"?>
<deviceinfo version="0.2">
  <device>
    <match key="info.product" string="TPPS/2 IBM TrackPoint">
      <merge key="input.x11_options.EmulateWheel" type="string">true</merge>
      <merge key="input.x11_options.EmulateWheelButton" type="string">2</merge>
      <merge key="input.x11_options.ZAxsisMapping" type="string">4 5</merge>
      <merge key="input.x11_options.Emulate3Buttons" type="string">true</merge>
    </match>
  </device>
</deviceinfo>

And Xorg.0.log then reports:

(II) config/hal: Adding input device TPPS/2 IBM TrackPoint
(**) TPPS/2 IBM TrackPoint: always reports core events
(**) TPPS/2 IBM TrackPoint: Device: "/dev/input/event10"
(II) TPPS/2 IBM TrackPoint: Found x and y relative axes
(II) TPPS/2 IBM TrackPoint: Found 3 mouse buttons
(II) TPPS/2 IBM TrackPoint: Configuring as mouse
(II) XINPUT: Adding extended input device "TPPS/2 IBM TrackPoint" (type: MOUSE)
(**) Option "Emulate3Buttons" "true"
(II) TPPS/2 IBM TrackPoint: Forcing middle mouse button emulation.
(**) Option "EmulateWheel" "true"
(**) Option "EmulateWheelButton" "2"
(**) TPPS/2 IBM TrackPoint: YAxisMapping: buttons 4 and 5
(**) TPPS/2 IBM TrackPoint: EmulateWheelButton: 2, EmulateWheelInertia: 10, EmulateWheelTimeout: 200
