我的 thinkpad x390 上的 wacom 显示屏出现问题。 Linux 不会对手写笔或笔上按钮的任何移动做出反应。我安装了 wacom 驱动程序。
这是输出libwacom-list-local-devices：
devices:
- name: 'Wacom ISDv4 51af'
bus: 'usb'
vid: '0x056a'
pid: '0x51af'
nodes:

- /dev/input/event7
这是输出xinput：

答案1
由于我面前没有该设备，因此我个人会采用以下一些方法来调试它。
如果您尝试xev在终端中运行，然后（当白色窗口聚焦时）查看终端输出，当
- 您按下平板电脑/手写笔上的任何按钮吗？
- 当您将手写笔悬停在平板电脑/屏幕上时？
- 当您将手写笔按下到平板电脑/屏幕时？
这将帮助您确定问题的根源是什么。
其他一些有帮助的问题包括：
- 它可以在 krita 或 inkscape 等绘图程序中运行吗？
- 您使用什么类型的窗口管理器和/或桌面管理器？
也许这可能会让您更接近这个问题的结论，在没有更多信息的情况下，这是我目前可以模糊回答的。
