蓝牙突然关闭，不再活动

Question

突然我的蓝牙被关闭了，我几乎做了我所知道的一切让它处于活动状态，没有任何反应！

看一下这个！我的蓝牙连接的屏幕截图

这是一些信息：

系统控制| grep -i 蓝色

输出：

我还尝试禁用和启用 bluetooth.service

须藤 systemctl 禁用 bluetooth.service

须藤 systemctl 启用蓝牙服务

我还重新安装了蓝牙：

sudo apt 删除 blueman

sudo apt 安装 blueman

然后我运行：

blueman-manager

输出：

blueman-manager version 2.1.2 starting
blueman-manager 14.45.44 ERROR    Manager:118 on_dbus_name_appeared: Default adapter not found, trying first available.
blueman-manager 14.45.44 ERROR    Manager:122 on_dbus_name_appeared: No adapter(s) found, exiting

所以，现在我很困惑。请问有人可以帮我吗？

Answer 1

我遇到过同样的问题。我找到了一个建议的解决方案：

1. 在 UEFI/BIOS 设置中禁用蓝牙
2. 重启
3. 在 UEFI / BIOS 设置中再次启用蓝牙
4. 重启

这对我有用。希望它也适合你。
