Connection to Bluez failed

General Help

Using Zorin 17.3 x86_64 on a ThinkPad T420. Find bluetooth mice work fine. Bluetooth keyboards can't be found. When running the blueman manager it produces the error message:

'Connection to BlueZ failed. BlueZ daemon is not running, blueman manager cannot continue. This probably means there were no Bluetooth adapters detected or Bluetooth daemon was not detected.'

Bluetooth is in the start up menu.

Have run the commands:

sudo systemctl enable bluetooth.service
sudo systemctl start bluetooth.service
systemctl enable --now bluetooth

Problem persists. Any suggestions welcome.

Can you check if the service is indeed running? And also if the kernel module is working just in case:

sudo systemctl status bluetooth
lsmod | grep btusb

Thanks for your reply. The dongle is in, and the bluetooth mouse is working.

sudo systemctl status bluetooth gives:

bluetooth.service - Bluetooth service
Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: >
Active: inactive (dead)
Docs: man:bluetoothd(8)

The command <lsmod | grep btusb> doesn't give anything

Hi, sorry for the delay.

There seems to be an issue with the Bluetooth service, which makes me wonder if your mouse is actually connected through Bluetooth directly to your computer, or to the receiver plugged in through USB?

In any case, try enabling this module with:

sudo modprobe btusb

And then run sudo systemctl restart bluetooth to see if that makes any difference. Perhaps even restart the computer as a whole, for good measure.
