"ThinkPad USB Keyboard with TrackPoint" 在 Ubuntu 10.04 的中鍵滾動設定方式

參考了我與小黑(ThinkPad X200s)之小紅點文章後，可輕鬆地設定了我的 R60e 中鍵滾動功能，然而一直無法在我的桌上型電腦上以 gpointing-device-settings 方法或是用 xinput 指令設定成功。因為設備名稱不同所以 "TPPS/2 IBM TrackPoint" 要改成 "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" ，但它就是不成功，指令如下：

# 啟用中鍵模擬功能
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Evdev Middle Button Emulation" 8 1
# 啟用滾輪模擬功能
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Evdev Wheel Emulation" 8 1
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Evdev Wheel Emulation Axes" 8 6 7 4 5
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Emulation Button" 8 2

# 靈敏度
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Evdev Middle Button Timeout" 8 50
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Evdev Wheel Emulation Inertia" 8 10
xinput set-int-prop "Lite-On Technology Corp. ThinkPad USB Keyboard with TrackPoint" "Evdev Wheel Emulation Timeout" 8 200

還好該文章有詳細參考文件 How to configure the TrackPoint ，從該文中，得知還有別種設定方法，所以我在 /usr/lib/X11/xorg.conf.d/20-thinkpad.conf 中，置入文句如下：

Section "InputClass"
 Identifier "Trackpoint Wheel Emulation"
 MatchProduct "TPPS/2 IBM TrackPoint|DualPoint Stick|Synaptics Inc. Composite TouchPad / TrackPoint|ThinkPad USB Keyboard with TrackPoint|USB Trackpoint pointing device"
 MatchDevicePath "/dev/input/event*"
 Option  "EmulateWheel"  "true"
 Option  "EmulateWheelButton" "2"
 Option  "Emulate3Buttons" "false"
 Option  "XAxisMapping"  "6 7"
 Option  "YAxisMapping"  "4 5"
EndSection

然後重開機，就搞定了。
