我正在尝试设置启用的“模拟中键单击属性”：
xinput set-prop "Logitech Gaming Mouse G402" "libinput Middle Emulation Enabled" 1
作为永久设置。
我试图通过配置 "/usr/share/X11/xorg.conf.d/" 来实现此目的。
目前我已经创建了一个文件，其中包含：
Section "InputClass"
Identifier "Mouse Middle click emulation"
MatchIsPointer "on"
Option "MiddleEmulation" "true"
Driver "libinput"
EndSection
理论上应该可以实现这一点。从我在日志中看到的内容来看，它至少被阅读了，但我不明白其中的大部分内容。
这是我在日志中读到的有关鼠标行为的内容：
