在 Ubuntu 上恢复 Apple Magic Trackpad 2 设置

尽管花了很多时间（两天），我还是无法解决这个问题，所以我决定在这里询问。 在 Ubuntu 上使用时，如何恢复 Apple Magic Trackpad 2 的默认设置？

我的问题如下：我正在使用 Ubuntu 20.04 LTS。使用 Apple Magic Trackpad 2 一段时间后没有出现重大问题，但它停止工作了。（我通过电缆使用它）。我总是要用力点击才能移动光标。无法使用。我找到了一种解决方法 这里（Apple Magic Trackpad 2 配置）

它建议使用类似命令

xinput 设置属性 17 296 2, 2, 0

我xinput list首先识别触控板的 ID（不是持久的！）。现在是 21。

⎜ ↳ Apple Inc. Magic Trackpad 2 id=21 [从属指针 (2)]

这些是我通过键入来识别的其属性xinput watch-props 21。

到目前为止，我还没有修改任何东西。根据上面提到的解决方法，我们现在需要识别“Synaptics Finger”ID，在本例中为 332（也不是持久的）：

xinput set-prop 21 332 2, 2, 0

此后，它似乎开始起作用了。

但是，每当我重新启动计算机或触控板时，所有更改都会消失。我最初为这些命令添加了快捷方式；但是，它并不有效，因为拔下触控板后 ID 往往会发生变化。我也考虑过编写一个脚本，但是，它应该在我插入/打开触控板时生效 - 而不是在打开计算机时。

我想删除连接此触控板时存储的所有设置。就像一开始一样。 类似于以下解决方案苹果系统。

到目前为止，我还尝试了以下命令恢复设置 - 但它们没有效果。 dconf reset -f / dconf reset -f /org/gnome/desktop/peripherals/mouse/ dconf reset -f /org/gnome/desktop/peripherals/touchpad/

在 Ubuntu 上使用时，如何恢复 Apple Magic Trackpad 2 的默认设置？或者，如何使这些更改持久？

非常感谢您的帮助！

我找到了一种使这些设置永久生效的方法。

将此部分添加到您的 /etc/X11/xorg.conf 文件中：

Section "InputClass"
    Identifier "Apple Magic Trackpad"
    MatchIsTouchpad "on"
    MatchUSBID "05ac:0265"
    Driver        "synaptics"
    Option        "VertScrollDelta" "50"
    Option        "HorizScrollDelta" "50"
    Option        "MinSpeed"        "0.6"
    Option        "MaxSpeed"        "1.3"
    Option        "AccelFactor"     "0.08"
    Option        "VertResolution"  "1"
    Option        "HorizResolution" "3"
    Option        "TapButton1"      "1"
    Option "TapButton3" "2"
    Option "VertEdgeScroll" "on"
    Option "VertTwoFingerScroll" "on"
    Option "HorizEdgeScroll" "on"
    Option "HorizTwoFingerScroll" "on"
    Option "CircularScrolling" "on"
    Option "CircScrollTrigger" "2"
    Option "EmulateTwoFingerMinZ" "40"
    Option "EmulateTwoFingerMinW" "8"
    Option "CoastingSpeed" "0"
    Option "FingerLow" "2"
    Option "FingerHigh" "2"
    Option "MaxTapTime" "125"
EndSection

这两个选项可以像 xinput 一样发挥作用：

Option "FingerLow" "2"
Option "FingerHigh" "2"

使用你的设备 ID 更新 USB ID，通过“lsusb”获取

希望有所帮助。

问候。

我使用以下脚本来设置 Logitech T650 和 Apple Magic Trackpad 2 的触控板设置

我使用 KDE 并将脚本添加为启动脚本，我保存了脚本~/bin/user-settings.sh，您可以通过执行手动调用它~/bin/user-settings.sh

我还需要调整的是

  1. 点按并拖动选择对我来说不起作用。单击并拖动以进行选择
  2. 我很不高兴无法在 KDE 中设置这些设置
  3. 你需要 libinput

我的系统上安装了以下软件包（Ubuntu 22.04 / KDE 5.24）
