rfkill将我的蓝牙列为软阻止：
root@zeljava:~# rfkill --output-all
ID TYPE DEVICE TYPE-DESC SOFT HARD
3 wlan phy1 Wireless LAN unblocked unblocked
4 bluetooth hci0 Bluetooth blocked unblocked
正在运行rfkill unblock all或者rfkill unblock bluetooth似乎无法打开：
root@zeljava:~# rfkill unblock bluetooth
root@zeljava:~# rfkill unblock all
root@zeljava:~# rfkill --output-all

我在 Dell Inspiron 5379 笔记本电脑上运行 Ubuntu 21.04。网络适配器是 Qualcomm 设备：

我检查了 BIOS，发现蓝牙已启用。我能找到的唯一明显相关的消息dmesg是：
[ 3639.167592] Bluetooth: hci0: unexpected event for opcode 0x0c03
[ 3639.169588] Bluetooth: hci0: unexpected event for opcode 0x1003

关于如何去除这个软块，有什么建议吗？
编辑：
我最终购买了一个新的适配器：

绝对地没有区别。在 BIOS 设置中禁用/启用蓝牙。尝试使用connman，将Powered属性设置为On使用bluez-tools，到目前为止没有任何效果...
唯一消耗的进程/dev/rfkill是 GNOME：
itor@zeljava:~$ fuser /dev/rfkill
/dev/rfkill: 6359
vitor@zeljava:~$ ps aux | grep 6359
vitor 6359 0.0 0.0 460376 6624 ? Ssl 18:31 0:00 /usr/libexec/gsd-rfkill
vitor 19955 0.0 0.0 11900 2252 pts/0 S+ 19:03 0:00 grep --color=auto 6359
现在，我可能会尝试删除此安装并再试一次。
