如何将 Synaptics TouchPad 的硬件右键单击按钮设置为中键？

  • 772

在 Windows 中，我可以根据需要配置 Synaptics TouchPad（和 TouchStyk）硬件单击按钮的操作。我怎样才能在 Kubuntu 中做到这一点？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。

我的笔记本是这张图片中的型号：HP EliteBook 850 G2。如您所见，上方有 2 个按钮（用于“TouchStyk”/跟踪点），下方有 2 个按钮（用于触摸板）。我只想更改右下角的按钮，并保留其他按钮。

我该如何设置？我需要安装一些东西吗？如果它没有实现，我应该在哪里发布一个问题报告，要求这个功能？

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似乎表明它用于点击板（我的不是点击板）。
顺便说一句，我认为这PS/2 Generic Mouse可能是它在没有特定驱动程序实现的情况下识别“TouchStyk”（跟踪点）的方式。（但这不太相关，因为我希望能够更改的按钮主要是下面的那些，触摸板按钮）。

    说明取自这篇文章。您可以使用 重新映射按钮xinput set-button-map。

    有趣的是，这篇文章声称这也应该在 Wayland 上工作，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，此命令的结果仅在您重新启动之前有效，因此您需要将该命令添加到自动启动。虽然，在 X11 上，您也可以使用 X11 配置文件进行设置，但 IMO 太复杂了，所以我的建议是：只需将命令添加到自动启动。

    最后，请不要xinput像在帖子中那样使用数字标识符。这些可能与重新启动不同，因此在某些时候您可能最终会在错误的设备上设置属性。使用字符串标识符，如下所示。

    为了保持一致性，我将使用我系统中的示例。

    首先，列出设备，找出哪一个是你的触摸板：

     λ xinput list

    ↳ 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，让我们看看它的按钮图：

     λ xinput get-button-map "DELL0768:00 06CB:7E92 Touchpad"
1 2 3 4 5 6 7

    根据我的理解，索引的含义可能会有所不同。要找到哪些按钮映射到您必须执行xev应用程序的索引，并尝试按下触摸板上的按钮。例子：

     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
[…]

    在这里你可以看到button 2和button 3是指数。这些事件是由我按下中间和右侧触摸板按钮触发的（要清楚：我没有硬件触摸板中间按钮，而是同时按下左右按钮。另外有趣的是，它是一个点击板，所以......是的，它也适用于点击板，以防有人想知道）。

    因此，现在您可以排列按钮：

     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，我都会得到一个中间按钮事件。你甚至可以设置，比如说， a 1 2 2 4 5 6 7 (重复2的 s)，所以没有办法用触摸板触发右键单击。
