在 Windows 中，我可以根据需要配置 Synaptics TouchPad（和 TouchStyk）硬件点击按钮的操作。如何在 Kubuntu 中执行此操作？设置中没有触摸板按钮的选项。我只能交换鼠标按钮，并模拟触摸板角落的点击，这不是我想要的。我想将触摸板下方的右键单击硬件按钮更改为中键单击。
我的笔记本是像这张图这样的型号：HP EliteBook 850 G2。如您所见，上面有 2 个按钮（用于“TouchStyk”/指点杆），下面有 2 个按钮（用于 TouchPad）。我只想更改右下角的按钮，并保留其他按钮。
我该如何设置？我需要安装什么东西吗？如果没有实现，我应该在哪里发布问题报告来请求此功能？
我在命令行上运行了它，但我认为它没有帮助。有Synaptics Click Action (338): 1, 1, 0，但info synaptics似乎表明它是用于点击板的（我的不是点击板）。
顺便说一句，我认为PS/2 Generic Mouse可能是它如何在没有特定驱动程序实现的情况下识别“TouchStyk”（指点杆）。（但这并不重要，因为我希望能够更改的按钮主要是下面的按钮，即触摸板按钮）。

已采取指示来自这篇文章。您可以使用 重新映射按钮xinput set-button-map。
有趣的是，文章声称这在 Wayland 上也应该有效，只是按钮映射可能不同，所以你需要重新配置它。另外，请注意，此命令的结果仅在你重新启动之前有效，因此你需要将命令添加到自动启动中。虽然在 X11 上，你也可以使用 X11 配置文件进行设置，但在我看来它们太复杂了，所以我的建议是：只需将命令添加到自动启动中即可。
最后，请不要xinput像在帖子中那样使用数字标识符。这些标识符可能因重新启动而异，因此有时您可能会在错误的设备上设置属性。请改用字符串标识符，如下所示。
为了保持一致性，我将使用来自我的系统的示例。
首先，列出设备，并找出哪一个是你的触摸板：
λ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ A4TECH USB Device Consumer Control id=15 [slave pointer (2)]
⎜ ↳ A4TECH USB Device id=16 [slave pointer (2)]
⎜ ↳ DELL0768:00 06CB:7E92 Mouse id=18 [slave pointer (2)]
⎜ ↳ DELL0768:00 06CB:7E92 Touchpad id=19 [slave pointer (2)]
⎜ ↳ Microsoft Wired Keyboard 600 Consumer Control id=11 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]

↳ Integrated_Webcam_HD: Integrate id=17 [slave keyboard (3)]

↳ DELL Wireless hotkeys id=22 [slave keyboard (3)]
↳ A4TECH USB Device Consumer Control id=24 [slave keyboard (3)]
↳ Microsoft Wired Keyboard 600 id=10 [slave keyboard (3)]

↳ Microsoft Wired Keyboard 600 System Control id=23 [slave keyboard (3)]
这里的触摸板是DELL0768:00 06CB:7E92 Touchpad。现在我们来看看它的按键图：
λ xinput get-button-map "DELL0768:00 06CB:7E92 Touchpad"
1 2 3 4 5 6 7
根据我的理解，索引的含义可能有所不同。要找到哪些按钮映射到哪个索引，您必须执行xev应用程序，并尝试按下触摸板上的按钮。示例：
λ xev
[…]
ButtonRelease event, serial 35, synthetic NO, window 0x5c00001,
root 0x7ba, subw 0x0, time 1191093641, (148,284), root:(1110,286),
state 0x210, button 2, same_screen YES
ButtonPress event, serial 35, synthetic NO, window 0x5c00001,
root 0x7ba, subw 0x0, time 1191096033, (148,284), root:(1110,286),
state 0x10, button 3, same_screen YES
ButtonRelease event, serial 35, synthetic NO, window 0x5c00001,
root 0x7ba, subw 0x0, time 1191096294, (148,284), root:(1110,286),
state 0x410, button 3, same_screen YES
[…]
在这里你可以button 2看到button 3是索引。这些事件是由我按下触摸板中键和右键触发的（需要说明的是：我没有硬件触摸板的中键，而是同时按下左键和右键。另外有趣的是，它是一个点击板，所以……是的，如果有人想知道的话，它也适用于点击板）。
现在，你可以排列按钮了：
λ xinput set-button-map "DELL0768:00 06CB:7E92 Touchpad" 1 3 2 4 5 6 7
瞧！现在每当我按下触摸板上的右键时，我都会收到中键事件。你甚至可以设置，比如说，1 2 2 4 5 6 7 （重复的2s），因此无法通过触摸板触发右键单击。
