Smile Deepin OS - Bluetooth disappeared - New User - Never used Linux before.


Hello everyone. I downloaded and installed Deepin OS yesterday. Never used Linux before.
Everything seemed to be working fine until my battery ran out. After rebooting the system my bluetooth icon disappeared from settings and I cant seem to find it anywhere. I tried searching on Google and YouTube but didn't find any solutions.


TL;DR

Battery ran out, after rebooting Bluetooth disappeared from settings, cannot find it anywhere else. Deepin OS.

Thank you.

Location: Earth? I would say I hope so but I'm not so sure about that... I could just be a figment of your imagination too.
Distribution: CentOS at the time of this writing, but some others over the years too...

You should make sure the system is still 'seeing' your bluetooth device.
Open a terminal window and then run the following command:

Code:
dmesg | grep -i bluetooth
Then post the output, using CODE tags - It should say something about your bluetooth device if it's being detected by the system.

Thank you for answering.

I got this after entering the code. Copy/Paste and typing it out manually.

Code:
dmesg: read kernel buffer failed: Operation not permitted

You need to run the command as the root user. 'sudo dmesg | grep Bluetooth'. Type what is between the quotes. If your system doesn't use sudo, you can use 'su' and enter the root password when prompted. Note, the password does not show, type it, and press enter.

Is this an icon that appears in the bar, at the top, or bottom of your desktop? If yes, in a terminal, type 'blueman-applet &' and press enter, and see if it re-appears.

I could see only Bluetooth in the settings but I cannot anymore after it disappeared.


Code:
[1] 2584
bash: blueman-applet: command not found

Do you have blueman-manager installed? I'm not familiar with Deepin, I run Slackware. Often the packages are different from distro to distro. Have a look in your package manager to see what is installed.

I'd check with rfkill if it is enabled first.
