有一张 Logitech Casa 弹出式办公桌（键盘和触控板）。使用带有 Ubutnu 20.04 的 Dell XPS 2-in-1。我还有一个 Logtech MX keys 和 MX keys mini，它们都运行良好。
我在将 Casa 的触控板或键盘与电脑配对时遇到了问题。对于键盘，GIU 只会说配对失败。我确实在某个阶段设法让键盘弹出一个 PIN 码，但它不起作用。触控板可以配对，但每次使用它时蓝牙都会完全崩溃。
我通过 sudo nano /etc/bluetooth/main.conf 将蓝牙模式从 bredr 更改为 dual（和 le），这样我就能看到键盘和触控板了
我改用 bluetoothctl，并能够配对键盘。
但是，无论何时我将触控板与 GUI 或蓝牙配对，它都会在我使用时崩溃。
我有点为难，因为 Casa 弹出式办公桌的全部重点在于触控板和键盘，因此如果我不能让它们同时工作，我就必须将其退回。
任何帮助都将不胜感激。我更喜欢 MX keys 的加密狗，但遗憾的是 Casa 和 MX mini 都不再配备加密狗，它们都是 BT。
