Bluetooth has stopped working

General system Kernel, boot, graphics & hardware

I don’t know what happened, but my bluetooth stopped working.
It’s been working fine so far and suddenly can’t find the adapter.

#bluetoothctl
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# power on
No default controller available

Is it turned off? rfkill list ?

Have you just updated the kernel and need to reboot?

Have you made any other recent changes, like this one:

?

3 
# rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

I have updated the kernel but not today.
I have installed libva-mesa-drivers, libva-utils, libva-vdpau-driver-chromium, then I deleted it libva-vdpau-driver-chromium.

I know a little about Linux because I’ve been using it for almost 20 years

What does this show

systemctl status bluetooth

Edit: If it is not working then try

sudo systemctl start bluetooth.service

sudo systemctl enable bluetooth.service

I did

sudo systemctl start bluetooth.service

sudo systemctl enable bluetooth.service

It didn’t do me any good. Bluetooth failed to start. I reinstalled the system and it’s OK now.

Thank you for your help. :smiley:

Have you tried using bluetoothctl to try to pair, register, trust connect etc. Sometimes removing what it’s trying to connect and going through the steps gets it working.
