在xfce環境下設置筆記本觸摸板的點擊功能

xfce桌面默認不支持觸摸板點擊，搜索了一大圈，最後找到解決方式，記錄一下。

第一步，安裝驅動

apt-get install xserver-xorg-input-synaptics

第二步，更改設置，在/usr/share/X11/xorg.conf.d/70-synaptics.conf裏相應地方增加如下設置：

        Option "TapButton1" "1"
        Option "TapButton2" "3"
        Option "TapButton3" "2"
        Option "VertEdgeScroll" "on"
        Option "VertTwoFingerScroll" "on"
        Option "HorizEdgeScroll" "on"
        Option "HorizTwoFingerScroll" "on"
        Option "CircularScrolling" "on"
        Option "CircScrollTrigger" "2"
        Option "EmulateTwoFingerMinZ" "40"
        Option "EmulateTwoFingerMinW" "8"
        Option "CoastingSpeed" "0"
        Option "FingerLow" "30"
        Option "FingerHigh" "50"
        Option "MaxTapTime" "125"
        Option "VertScrollDelta" "-111"
        Option "HorizScrollDelta" "-111"
