centos 6.5 thinkpad trackpoint 中间键 滚动设置

在 /etc/X11/xorg.conf.d中建立Trackpoint.conf文件，写下以下内容：

Section "InputClass"
    Identifier        "Wheel Emulation"
    MatchIsPointer        "on"
    MatchProduct        "TrackPoint"
    Option            "EmulateWheelButton" "2"
    Option            "EmulateWheel" "on"
    Option            "XAxisMapping"        "6 7"
    Option            "YAxisMapping"        "4 5"
    Option            "ZAxisMapping"        "4 5"
    Option            "Emulate3Buttons"    "true"
EndSection

然后重启就可以用了。
