有人知道为什么在 Wacom Intuos Pro M 上翻转笔似乎无法可靠地工作吗？通常当我翻转笔时，功能会从触控笔变为橡皮擦。但并非总是如此。因此，在 Gimp 或 Inkscape 中，当我翻转笔时，工具不会改变。奇怪的是，有时它可以工作，有时则不行。
如果笔记本电脑进入睡眠模式，这种情况似乎最常发生，睡眠时间越长，发生的可能性就越大。同样，如果 Gimp 在笔记本电脑睡眠时运行，这种情况似乎更有可能发生。通常，如果它在应用程序中不起作用，它在“设置”>“Wacom 平板电脑”>“测试您的设置”中也不起作用，但并非总是如此。有时在设置中检测到笔翻转，但在 Gimp 中未检测到。
有时关闭打开的应用程序，拔下 Wacom 并重新插入可以解决问题，有时则不行。注销或重新启动通常可以解决问题，但并非总是如此。
我已经无数次重新安装了 Wacom 库，包括删除它们 - 提示不要这样做。
禁用安全启动没有什么区别。
重新安装 Gimp 没有任何区别，将输入设备重置为默认值也没有区别。
下面发布了我认为可能有帮助的内容，但如果有事件日志或其他内容，请告诉我。
提前致谢。
