X 中使用第二个鼠标 mini-HOWTO
上一篇下一篇

5. XFree 4.x

使用 XFree 4.x，任务变得更加简单。首先，主鼠标通常已经存在于配置文件中
Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Device" "/dev/mouse"
        Option      "Protocol" "PS/2"
        Option      "Emulate3Buttons" "off"
        Option      "ZAxisMapping" "4 5"
EndSection
要添加另一个鼠标，只需复制以上部分并进行修改，使其读取
Section "InputDevice"
        Identifier  "Mouse1"
        Driver      "mouse"
        Option      "Device" "/dev/input/mice"
        Option      "Protocol" "IMPS/2"
        Option      "Emulate3Buttons" "off"
        Option      "ZAxisMapping" "4 5"
EndSection
这样，您可以根据需要定义任意数量的附加指针，这同样适用于操纵杆和平板电脑。

为了使两个鼠标协同工作，还需要对XF86Config文件进行另一项更改。有一个名为 *ServerLayout* 的部分，其中指定了所有组件。以下是在添加第二个鼠标*之前*的样子
Section "ServerLayout"
        Identifier "XFree86 Configured"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection
这是添加第二个鼠标*之后*的样子
Section "ServerLayout"
        Identifier "XFree86 Configured"
        Screen      0  "Screen0" 0 0
        InputDevice    "Mouse0" "CorePointer"
        InputDevice    "Mouse1" "AlwaysCore"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection
