mir*_*zal 7 hardware dell stylus
我在戴尔 Inspiron 13 7000 二合一黑色版 (7391) 上运行 Ubuntu 19.10。笔记本电脑配备了一个非常好的触控笔，戴尔 PN350M 有源触控笔，不幸的是，它在我的系统下根本无法使用。在网络上稍微挖掘一下就会发现，该笔使用 Microsoft Pen 协议与笔记本电脑而不是蓝牙配对。支持这些吗？谷歌让我没有答案。

下面是 xinput 的更新输出。这里有一些可疑的东西，特别是“未知”的东西。

我设法使用 evdev 和 libevdev 库创建了一个 python 驱动程序。我正在创建一个虚拟设备，然后简单地传递我从手写笔找到的事件。它正在处理压力事件和跟踪，但我无法让按钮工作。
只需复制此内容并将其标记为可执行文件，您将看到一个名为“自定义手写笔”的设备应该可以工作。为了进一步使其无缝，我将其添加到 中，gnome-session-properties以便它在启动时运行脚本。
希望这可以帮助！
