我是直接关闭蓝牙的。
你先看看sudo systemctl status bluetooth是否有状态

你这蓝牙服务未启动

1. 首先你得有蓝牙模块。笔记本应该自带，台式机我就不知道了。没有的话，就买一个。并且BIOS里面不能禁用蓝牙。
2. sudo systemclt start bluetooth; sudo systemctl enable bluetooth

microcheung@microcheung-PC:~$ sudo systemclt start bluetooth
sudo: systemclt：找不到命令
microcheung@microcheung-PC:~$ sudo systemctl enable bluetooth
Synchronizing state of bluetooth.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable bluetooth
microcheung@microcheung-PC:~$

是不是驱动问题，升级内核试试。而且命令应该是 systemclt不是systemctl，应该是他写错了。说下你的网卡型号。

systemctl，我命令打错了

https://github.com/charlesvg/wifiscan
只找到一个无线网的，蓝牙的不清楚。。。

谢谢了 我试试

不会用github上面的东西

翻译成中文啊！他说的意思是运行setup.sh .
你可以试试 sudo bash ./steup.sh

我把内核升级到5.6了都不行

更新硬件驱动：linux-firmware
可以从这里下载Ubuntu的硬件驱动最新版：http://ftp.sjtu.edu.cn/ubuntu/pool/
main/l/linux-firmware/
例如当前最新版：http://ftp.sjtu.edu.cn/ubuntu/pool/main/l/linux-firmware/
linux-firmware_1.186_all.deb
下载安装，重启。
如果问题仍然无法解决，请尝试升级内核。

我试试吧 现在内核已经升级到5.6了

内核是最新的 驱动也是最新的 还是不行啊

楼上liwl兄弟的命令输错了，他后面又提到过，不知楼主有没有按他的方法再试一下，如果试过了，也更新了驱动和内核，还是不行的话，那只说明不支持你的蓝牙了

蓝牙现在是弄出来了就是不能搜索   重启后就就又不行了 笔记本肯定是支持蓝牙的啊  以前win10就可以用 现在就是单独的deepin系统了

我之前也出现过这个问题，双系统win10和deepin15.11，一直到好的不知道什么时候蓝牙就没了，设置里也看不到蓝牙选项了，进win里蓝牙正常，上面的办法我也都试过了，最后重装deepin差不多有半年了吧，蓝牙一直正常，没有换任何驱动和内核
