從這邊 http://ubuntuforums.org/showpost.php?p=127713&postcount=4 看到的, 完全不用動到驅動程式的部分, 只要改一下 xorg.conf 就可以了, 我是加了倒數四行, 中鍵捲軸就有作用了:
Section “InputDevice”
Identifier “Configured Mouse”
Driver “mouse”
Option “CorePointer”
Option “Device” “/dev/input/mice”
Option “Protocol” “ImPS/2”
Option “Emulate3Buttons” “true”
Option “ZAxisMapping” “4 5”
Option “EmulateWheel” “true” < == add this line Option "EmulateWheelButton" "2" <== add this line EndSection
