我正在尝试在触控板上默认启用点击功能。设备名称是“bcm5974”。xinput --set-prop "bcm5974" "libinput Tapping Enabled" "1"很有魅力，但是像这样更改的属性在重新启动后不会保留。
根据此处的其他答案，我修改了/usr/share/X11/xorg.conf.d/40-libinput.conf.首先我运行xinput list，我的设备作为指针出现，因此相关部分40-libinput.conf变为：
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "Tapping" "on"
EndSection
这不起作用，所以我查看了/var/log/Xorg.0.log，它表明该设备实际上被识别为触摸板。我改为40-libinput.conf添加Option "Tapping" "on"到触摸板InputClass。
重新启动后，点击点击仍然未启用，但确实Xorg.0.log显示了正在设置的选项，然后设备被删除，然后显然是在没有读取的情况下读取的40-libinput.conf。

我在这里超出了我的知识水平。 udev 是否将其自己的配置应用于我的设备？如果是，配置文件位于何处以及如何修改它？或者我还缺少其他东西吗？
我在一台 2008 年末的 Macbook 上运行 Lubuntu 20.04.5，触控板是笔记本电脑原来的内置触控板。谢谢你尽你所能的帮助！
