微軟筆協議支持

我在 Dell Inspiron 靈越 13 7000 二合一黑色版 (7391) 上運行 Ubuntu 19.10。這台筆記型電腦配備了一支非常漂亮的手寫筆，即戴爾 PN350M 有源筆，但不幸的是，它根本無法在我的系統下使用。在網路上進行一些挖掘後發現，該筆使用 Microsoft Pen 協定而不是藍牙與筆記型電腦配對。這些支持嗎？谷歌沒有給我答案。

以下是 xinput 的更新輸出。這裡有一些可疑的東西，特別是「未知」的東西。

我設法使用 evdev 和 libevdev 庫創建了一個 python 驅動程式。我正在創建一個虛擬設​​備，然後簡單地傳遞我從手寫筆找到的事件。它正在處理壓力事件和跟踪，但我無法讓按鈕工作。

只需複製此內容並將其標記為可執行文件，您將看到一個名為“自訂手寫筆”的設備應該可以工作。為了進一步使其無縫，我將其添加到 中，gnome-session-properties以便它在啟動時運行腳本。

希望這可以幫助！

有同樣的問題。我使用的是 15" 銀色。有一個想法，您可能會使用使用該協議的 wacom 驅動程序？但除此之外，您還必須以某種方式獲得 mpp 驅動程序，儘管我不確定在哪裡
