GIMP: GIMP not detecting / recognize WACOM

The pen pressure setting of GIMP works on the office computer, but not my laptop.
I googled " GIMP WACOM NOT" etc...
And try any ways I could do.
Actives GIMP by pen not mouse.
Updated and reinstall WACOM Drive.
Reinstall GIMP.
a couple hours later it was 1:30 am them I gave up.
I though it might be the wacom intous2 problem.
But when I waked up this morning, I found this site

The " Tablet Preference File Utility ", which I haven't find in other article.
So I removed My Preferences and All User Preferences both, then launch GIMP again.
It works!!!

The version of GIMP : 2.8
Windows system : win7
Input Device : wacom intuos 2

GIMP - How to settup pen Pressure 如何設定筆壓感應

It was first time using GIMP, the function I need was pen pressure!
I tried to changed the setting on Tool Options panel but it seems not working.

without pen pressure, GIMP will be useless!
I took a quick look the tutorial but  there has nothing I need.
Finally, I found the Input Devices in Edit menu.
Select "WACOM Tablet Pressure Stylus" and change the "Mode" to Screen.
change the Pressure Curve if you need.
That's it!!
now you should get the pen pressure!

第一次使用GIMP，而第一個要找的功能就是筆壓感應！
一個繪圖軟體怎麼可以沒有這個功能！
筆刷設定裡找不到
教學裡也找不到
最後在編輯（edit）裡發現輸入裝置（Input Devices）的選單
選擇 "WACOM Tablet Pressure Stylus" 將"mode"改成Screen就可以了
可以再另外調整壓力曲線。
