安装了此项功能，可以在/etc/X11/xorg.conf中，Configured Mouse部分加入：
引用:Option "EmulateWheel" "on"
Option "EmulateWheelButton" "2"
Option "EmulateWheelTimeOut" "200"
Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
以下的配置在我的电脑（IBM R50p,1836）上测试通过
引用:Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "Emulate3Buttons" "on"
Option "Emulate3TimeOut" "50"
Option "EmulateWheel" "on"
Option "EmulateWheelTimeOut" "200"
Option "EmulateWheelButton" "2"
Option "YAxisMapping" "4 5"
Option "XAxisMapping" "6 7"
Option "ZAxisMapping" "4 5"
EndSection
重启X或计算机，滚轮就可以用了。
话说回来,ubuntu 上网就是快,广电网络1.6M带宽+wireless路由:基本没有小于就没有低于400k,
而原来同1台电脑,用xp就貌似没有高于200k,
难道是RPWT?
使用心得随后.
