Hello

I installed blueberry and Blueman however, it is not working.

Have you enabled and started the bluetooth service in Systemd?

yep and nothing work.

Dump yer inxi output... you'll need to search how...and post it, along with your bluetooth hardware info.

I'm on an unfamiliar device ATM. Someone else may want to step in here. Paging @dalto

My inxi output:

thanks in advance man.

having the same issue! bluetooth was working fine until I rebooted last time.
when I run bluetooth status, I get vendor as dead!

sudo systemctl status bluetooth
● bluetooth.service - Bluetooth service
Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor>
Active: inactive (dead)

As always, please try at least one other kernel as well as the LTS kernel. Sometimes that can make a difference. I've lost things like Bluetooth or audio when updating to newer kernels.

If you're new, usually you end up installing the newest kernel only initially. You will have a program called kernel you can add them in.

I personally did not have very good luck with the 5.6.X kernel you're currently using. 5.4 with perfect for me.

Ditto. I'm on mainline and I noticed the lack of eMMc card recognition on my machine yesterday with 5.6--and it's a modern machine. The LTS worked as intended.

And 5.6 is dead or EOL - has been for some time.

Please up to 5.7

The same happened to me

Regarding my case, should I move to 5.7 or 5.4 kernel?

Ideally both. It's not required but generally good practice to have both the latest and LTS kernel available for reasons just like this. Unless you have very new hardware, I usually recommend the LTS for daily driver for most people.

it still not working

In which kernel, or both? Could you again post the full inxi -Fxxxza --no-host again

Also, it shows that bluetooth.service is loaded, but not active. Did you try and start bluetooth.service again?
