Wacom 平板电脑未检测到 ubuntu 20.04、HP probook x360 435 G7

我使用的是 HP Probook x360 435 G7 笔记本电脑，上面安装了 ubuntu 20.04。既没有检测到 Wacom 平板电脑，也没有检测到触控笔。

这是蓝牙已打开的情况： 在此处输入图片描述

以下是各种命令的输出：

注意，安装并尝试了 kde_wacom_tablet，但它崩溃了。它没有检测到任何平板电脑。

您的设备似乎使用了 ELAN 传感器。libwacom 平板电脑数据库不包含很多 ELAN 传感器，GNOME 控制中心不允许您配置数据库中没有的任何设备。您可以按照wacom-hid-descriptors“贡献”说明分享有关您的系统的信息，并希望有人可以根据数据创建平板电脑定义。他们定期为 Wacom 传感器创建定义，但他们的开发人员对 ELAN 硬件不太熟悉...
