![XPS 13 上的蓝牙问题](https://linux22.com/image/1183537/XPS%2013%20%E4%B8%8A%E7%9A%84%E8%93%9D%E7%89%99%E9%97%AE%E9%A2%98.png)
我在 Dell XPS 13 9300 上运行 Ubuntu 21.04。
我的所有蓝牙设备都不断断开并重新连接。
这是一个问题,因为我的鼠标、键盘和耳机都使用蓝牙。我以前可以同时使用这三个设备,没有任何问题。
我尝试将内核从 5.11 降级到 5.10,但没有效果。
该问题于本周某个时候开始出现。
附件是过去 3 天内升级的所有软件包,以及过去 14 天内所有升级的软件包的列表,以防新软件包均未成功。
知道其中哪些会影响蓝牙吗?
