触控板停止工作，但蓝牙鼠标照常工作。仅在登录后发生。

xinput 输出：

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ DLL075B:01 06CB:76AF Mouse                id=11   [slave  pointer  (2)]
⎜   ↳ DLL075B:01 06CB:76AF Touchpad             id=12   [slave  pointer  (2)]
⎜   ↳ Designer Mouse                            id=18   [slave  pointer  (2)]
⎜   ↳ Designer Keyboard Consumer Control        id=22   [slave  pointer  (2)]

对于 12，这里是道具：

我该如何进一步修复/调试它？

经过多天调试后发现触摸板设置已关闭，我不知道为什么，也不记得这样做了。
