在 /etc/hal/fdi/policy/ 下建立文件 mouse-wheel.fdi，加入下述內容：
<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.YAxisMapping” type=”string”>4 5</merge>
<merge key=”input.x11_options.XAxisMapping” type=”string”>6 7</merge>
<merge key=”input.x11_options.Emulate3Buttons” type=”string”>true</merge>
<merge key=”input.x11_options.EmulateWheelTimeout” type=”string”>200</merge>
</match>
重開機，然後就可以使用滾輪功能了。

在 10.04 中：
回覆刪除在終端機輸入sudo gedit /usr/lib/X11/xorg.conf.d/20-thinkpad.conf
