lenovothinkpadt460sopensuselinux下禁用多點觸控屏

KDE對多點觸控屏的支援沒有windows那麼優秀，只能使用類似滑鼠的單擊操作。
下面是直接使用xinput禁用。

thinkt@linux-pw37:/usr/share/X11/xorg.conf.d> xinput disable 9
也可以修改/usr/share/X11/xorg.conf.d/10-evdev.conf，新增Option “Ignore” “on”

Section “InputClass”
        Identifier “evdev touchscreen catchall”
        MatchIsTouchscreen “on”
        MatchDevicePath “/dev/input/event*”
        Driver “evdev”
        Option “Ignore” “on”
EndSection
