您可能已经看到了，这是我的第一篇文章。因此，我已经尝试并研究了很多，但我仍然无法解决这个问题。
我真的很喜欢自然滚动，不仅在触摸板上，在鼠标上也一样——但到目前为止，这还不起作用。我目前的设置是 Ubuntu 18.04.2，安装在 2012 年末的 MacBook（第一台 hidpi）上，配有 i3 wm，我使用性能 MX 罗技鼠标。这是我昨天安装的一个相当新的设置。
我确实使用 synaptics 反转了触摸板滚动并尝试使用 xmodkeys 修改鼠标键，但没有效果。
xmodmap -e 'pointer = 1 2 3 5 4 6 7 8 9 10 11 12'
奇怪的是，当我使用 xev 测试时，我的鼠标按钮实际上是反转的（4 和 5），但这不会影响滚动行为。我也可以重新映射其他鼠标键，但滚动似乎无法改变。

答案1
编辑/usr/share/X11/xorg.conf.d/40-libinput.conf
Option "NaturalScrolling" "True"像这样添加：
对于你的鼠标：
# Match on all types of devices but joysticks
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "NaturalScrolling" "True"
EndSection
对于触摸板：
Section "InputClass"
Identifier "libinput touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "NaturalScrolling" "True"
EndSection
然后注销并重新登录进行申请。
