ubuntu如何开启触摸板的点击功能

今天突然发现ubuntu的触摸板点击功能失效了，可以是升级的原因吧

现在触摸板可以移动鼠标

那么解决这个问题也很简单

首先终端输入以下命令查看当前状态

synclient -l

显示如下内容

Parameter settings:
    LeftEdge                = 1756
    RightEdge               = 5258
    TopEdge                 = 1622
    BottomEdge              = 4256
    FingerLow               = 25
    FingerHigh              = 30
    MaxTapTime              = 180
    MaxTapMove              = 224
    MaxDoubleTapTime        = 100
    SingleTapTimeout        = 180
    ClickTime               = 100

    LockedDrags             = 0
    LockedDragTimeout       = 5000

    LBCornerButton          = 0
    TapButton1              = 0
    TapButton2              = 0
    TapButton3              = 0
    ClickFinger1            = 1
    ClickFinger2            = 3
    ClickFinger3            = 0
    CircularScrolling       = 0
    CircScrollDelta         = 0.1
    CircScrollTrigger       = 0
    CircularPad             = 0

    PressureMotionMinFactor = 1
    PressureMotionMaxFactor = 1
    ResolutionDetect        = 1
    GrabEventDevice         = 0
    TapAndDragGesture       = 1
    AreaLeftEdge            = 0
    AreaRightEdge           = 0
    AreaTopEdge             = 0
    AreaBottomEdge          = 0
    HorizHysteresis         = 8
    VertHysteresis          = 8
    ClickPad                = 1
    RightButtonAreaLeft     = 3507
    RightButtonAreaRight    = 0
    RightButtonAreaTop      = 3918
    RightButtonAreaBottom   = 0
    MiddleButtonAreaLeft    = 0
    MiddleButtonAreaRight   = 0
    MiddleButtonAreaTop     = 0
    MiddleButtonAreaBottom  = 0

上面代码我加粗变红色的代码是我们需要更改的代码

TapButton1              = 0
TapButton2              = 0
TapButton3              = 0

那么如何修改呢？

请输入以下命令

synclient EmulateMidButtonTime=1    //改为1表示，开启中键功能
synclient TapButton1=1　　                  //改为1表示开启左键
synclient TapButton2=3　　                 //改为3表示，在未开启中键时代表回车，开启中键后代表中键
synclient TapButton3=2　　                //改为2，表示右键
