If I try and use the bluetooth toggle in gnome settings upon boot it won't do anything. If I have the bluetooth settings window open in gnome settings and manually restart the bluetooth service with: "sudo systemctl restart bluetooth" then it starts searching for devices and I was able to pair Samsung Galaxy Earbuds after multiple service restarts.

[Daniel van Vugt (vanvugt)]

There was a suggestion in bug 1912940 that the latest hirsute updates have fixed the problem. Please run:

  sudo apt update
  sudo apt full-upgrade

and tell us if the problem persists.

[Freeman (gordon.freeman)]

I ran the updates and rebooted. Bug is not fixed, same problem as before persists. Bluetooth is non-functional until systemctl restart bluetooth.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

[Kai-Heng Feng (kaihengfeng)]

Is this a regression? Does the Bluetooth work under 20.04?

[Freeman (gordon.freeman)]

Correct. Bluetooth works on 20.04 desktop.

[Kai-Heng Feng (kaihengfeng)]

Is it possible to find out it's a kernel regression or a firmware one?
