can you give instructions on how to do the override?
可以将synaptics配置文件复制到/etc/X11/xorg.conf.d,并为其指定一个比默认值/usr/share/X11/xorg.conf.d synaptics.conf高的编号。然后,突触触摸板驱动程序将具有更高的优先级,从而覆盖libinput触摸板驱动程序。
可以将一个选项添加到libinput.conf中,以防止考虑使用libinput触摸板驱动程序。在“ MatchIsTouchpad”之后添加:
Option "Ignore" "true"
用xinput检查:
xinput list
xinput --list-props "whatever touchpad from above list"
如果触摸板分别使用libinput或synaptics,则将显示libinput或synaptics属性。突触触摸板驱动程序应显示如下输出:

当libinput驱动程序仅打开或关闭一些功能时,synaptics触摸板驱动程序允许调整许多设置,因此对我的触摸板没有用。
