I've installed ubuntu 24.04 on my geecom A7. And I wasn't able to figure out why bluetooth is not working. Problem looks same as described here:

https://www.cnx-software.com/2024/02/24/geekom-a7-mini-pc-review-ubuntu-22-04-ubuntu-24-04-linux/

For the record, bluetooth works fine on windows (on same mini PC).

  1. rfkill shows that Bluetooth is not blocked.

I just upgraded from 22.04 to 24.04 and ran into the exact same problem. Found a "solution" that had me entering in terminal:

systemctl --user enable pulseaudio
systemctl --user start pulseaudio

This worked for me but it does not persist between sessions. Had to add these two lines to my .xsessionrc file in my home directory to make it persist. That's not a real solution but, until a real fix is released, it has to do.

First remove the config file for PulseAudio with:

rm  -rf ~/.config/pulse/*

Then restart your machine where the PulseAudio will be reconfigured automatically giving you a dependency error. For my case, the desktop environment did not load at first. So I installed GNOME via terminal. Οnce installed, I tried to install a different environment for Ubuntu 24.04 with:

sudo apt install ubuntu-unity-desktop

This gives an error message:

The following packages have unmet dependencies:
 ubuntu-unity-desktop : Depends: pulseaudio
                        Recommends: pulseaudio-module-bluetooth but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

So I installed the recommended package, pulseaudio-module-bluetooth, which worked fine. However the Bluetooth couldn't connect and hold, so I inputted the following commands to fix this:

systemctl --user enable pulseaudio

followed by:

systemctl --user start pulseaudio

Worked perfectly.

I had a similar problem. While searching for a solution, I focused my attention on the

bluetoothctl reports that there is no default controller.

I've checked if Bluetooth firmware is installed by the command:

ls /lib/firmware/brcm

There should be a file BCM43142A0-0a5c-21d7.hcd or similar to that.

I didn't have it. Then that file was downloaded and copied to /lib/firmware/brcm from https://github.com/winterheart/broadcom-bt-firmware

In my case:

sudo cp BCM43142A0-105b-e065.hcd /lib/firmware/brcm/

The next step is restarting the Bluetooth service btusb

sudo modprobe -r btusb
sudo modprobe btusb
sudo systemctl restart bluetooth

That was useful for me. For testing run:

bluetoothctl
[bluetooth]# power on

Hope it will be useful.

I have the same issue as the main question, I have tried everything, it seems to be an issue with MT7921e chipset and its firmware, the weired thing is that this chipset controls both wifi and bluetooth, and wifi workd fine, for sure your situation is the same

I had a similar issue (not sure if it's exactly the same): basically the bluetooth connections worked perfectly fine for a few times after installation until it suddenly just... stopped working. It couldn't find any devices at all. I've tried every single suggestion I could find on the internet, from restarting the bluetooth service, the pulseaudio ones, downloading the driver ones, extracting the .zst files in /lib/firmware/brcm, installing blueman, etc. to just rebooting everything. Nothing worked, until I found this little reply on reddit:

https://www.reddit.com/r/Ubuntu/comments/1cf30qo/comment/lo6ks4x/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

Basically, just let the battery completely drains out, charge it and start the laptop. And voila! It magically works now.

I hope this might work for you and for anyone else coming across this!

I have tried all solutions proposed here at this time and none worked... I just activated the proprietary driver for Nvidia and all worked fine.

In my case I used the recommended one: nvidia-driver-570 on a Latitude-5580
