ubuntu Linux下指点杆中键滚动功能的配置

第一种方法，不但可以上下滚动，还可以左右滚动：
修改/etc/X11/xorg.conf，找到Configured Mouse一段

Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "Emulate3Buttons" "true"
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

但在默认配置下，firefox里的左右滚动是前进和后退功能，这样在上下滚动时一不小心就会出现网页前进和后退，很不爽。
修改左右滚动功能的方法是，在firefox地址栏中输入

about:config

回车。更改下列设置：

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;

firefox的配置项很多，别忘了使用过滤器。
修改完以上配置就可以了，这时中键的左右滚动就可以控制网页的左右滚动，很适合浏览大的网页。

第二种方法，不支持左右滚动，也不用修改firefox的配置

还是修改xorg.conf，但内容略有不同：
Section "InputDevice"
Identifier "Configured Mouse"
Driver "vmmouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ImPS/2"
Option "Emulate3Buttons" "true"
Option "EmulateWheel" "true"
Option "EmulateWheelButton" "2"
Option "ZAxisMapping" "4 5"
EndSection
