触摸板 - 双指滚动不起作用

我有一台安装了 kubuntu 18.04 的 ASUS N750JV 笔记本电脑，我正在努力让双指滚动工作。默认 libinput 安装为触摸板驱动程序。这是输出xinput -list：

⎡ Virtual core pointer                          id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ PS/2 Logitech Wheel Mouse                 id=14   [slave  pointer  (2)]
⎣ Virtual core keyboard                         id=3    [master keyboard (2)]
    ↳ Virtual core XTEST keyboard               id=5    [slave  keyboard (3)]
    ↳ Power Button                              id=6    [slave  keyboard (3)]
    ↳ Asus Wireless Radio Control               id=7    [slave  keyboard (3)]
    ↳ Video Bus                                 id=8    [slave  keyboard (3)]
    ↳ Video Bus                                 id=9    [slave  keyboard (3)]
    ↳ Sleep Button                              id=10   [slave  keyboard (3)]
    ↳ USB2.0 UVC HD Webcam: USB2.0 UV           id=11   [slave  keyboard (3)]
    ↳ Asus WMI hotkeys                          id=12   [slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard              id=13   [slave  keyboard (3)]

这是输出xinput list-props 14

我已将以下选项设置为/usr/share/X11/xorg.conf.d/40-libinput.conf：

Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
        Option "Tapping" "true" 
        Option "ClickMethod" "clickfinger"
        Option "NaturalScrolling" "true"
        Option "ScrollMethod" "twofinger"
EndSection

但仍然不起作用。谢谢你的帮助。

您可以在系统设置中打开鼠标和触摸板菜单，并确保已启用双指滚动。
