你小黑的滾輪中鍵不理你嗎？

請你跟我這樣作

找到你/etc/X11 下面的 xorg.conf，ok！到終端機去輸入：

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf-backup
sudo gedit /etc/X11/xorg.conf

（先做個備份，再開啟它！）

在gedit中,找到InputDevice部分中Configured Mouse，在EndScetion前增加：

Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"

如果想使用水平scroll增加:

Option "XAxisMapping" "6 7"
Option "YAxisMapping" "4 5"

若要在firefox裡也有這樣的動作還要打開about:config

mousewheel.horizscroll.withcontrolkey.action = 3;
mousewheel.horizscroll.withcontrolkey.numlines = 1;
mousewheel.horizscroll.withcontrolkey.sysnumlines = true;

mousewheel.horizscroll.withnokey.action = 0;
mousewheel.horizscroll.withnokey.numlines = 1;
mousewheel.horizscroll.withnokey.sysnumlines = true;

mousewheel.horizscroll.withshiftkey.action = 1;
mousewheel.horizscroll.withshiftkey.numlines = 1;
mousewheel.horizscroll.withshiftkey.sysnumlines = true;

完成！有人說馬上就可以用！但我覺得X-Window重開會比較好！
