Archlinux Touchpad 设置

在安装完成Archlinux之后，发现Touchpad过于灵敏，指针跑来跑去很不舒服，而且Touchpad侧边也没有翻页的功能。

修改方法如下：

1. 安装synaptics：sudo pacman -S xf86-input-synaptics RET
2. 修改10-synaptics.conf文件：sudo kate /etc/X11/xorg.conf.d/10-synaptics.conf RET
Section "InputClass"
Identifier "touchpad"
Driver "synaptics"
MatchIsTouchpad "on"
Option "TapButton1" "1"
Option "TapButton2" "2"
Option "TapButton3" "3"
Option "VertEdgeScroll" "on"
Option "VertTwoFingerScroll" "on"
Option "HorizEdgeScroll" "on"
Option "HorizTwoFingerScroll" "on"
Option "CircularScrolling" "on"
Option "CircScrollTrigger" "2"
Option "EmulateTwoFingerMinZ" "40"
Option "EmulateTwoFingerMinW" "8"
EndSection

3. 保存之后，重启电脑即可。
