lenovo thinkpad t460s opensuse linux 下禁用多点触控屏

KDE对多点触控屏的支持没有windows那么优秀，只能使用类似鼠标的单击操作。

下面是直接使用xinput禁用。

也可以修改/usr/share/X11/xorg.conf.d/10-evdev.conf，添加Option "Ignore" "on"

Section "InputClass"

        Identifier "evdev touchscreen catchall"

        MatchIsTouchscreen "on"

        MatchDevicePath "/dev/input/event*"

        Driver "evdev"

        Option "Ignore" "on"
