Thinkpad T61 － 在Fedora 10下启用小红帽加中键的滚动功能

安装Fedora 10之后，小红帽加中键的滚动功能未开，上网查了方法，如下：
修改/etc/X11/xorg.conf文件，如果没有可以创建，新增内容如下：

Section "ServerFlags"
       Option  "AutoAddDevices"        "false"
EndSection
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

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

在Section "ServerLayout"中，去掉（如果有的话）
 InputDevice    "Synaptics" "CorePointer"

加入：

InputDevice "Configured Mouse" InputDevice "Synaptics Touchpad"

配置完成，重新启动X就可以看到效果。
