I keep having my bluetooth turned off in ubuntu 19.04. it happens if I physically turn off or disconnect my Bluetooth speaker. Bluetooth in ubuntu 19.04 won’t turn on even if the slider is on “on” mode. I have to restart ubuntu several times to make it work. I already reinstalled Bluetooth but still, it happens.
anybody here who has the same problem or have a fix for it?
On Linux and/or macOS, how can I check if a device is vulnerable to a Key Negotiation of Bluetooth (KNOB) Attack?
And if a device is vulnerable, is there something I can do to mitigate the danger?
Bluetooth in Ubuntu seems not as robust! I am using a DELL inspirion Intel(R) Core(TM) i5-4210U CPU @ 1.70GHz and there’s always some glitch connecting to my bose soundlink/bluetooth mouse or to any other device. The same gadgets work fine with my mobile and other windows machines.
Am i missing anything or what can i do from my part to fix this or if Ubuntu can fix this! Attached image clearly speaks.

I have an MX Anywhere 2 bluetooth mouse. I’m running 18.04.3 LTS. But I can’t get the mouse to connect.
I’ve run the whole:
- power on
- power off
- scan on
- connnect / pair MAC Address
But I just get a
Failed to connect: org.bluez.ErrorFailed” or Failed to connect: org.bluez.ErrorAuthenticationFailed
error and I’m not sure what else to try.
When I run gnome-control-center -v bluetooth using the Ubuntu desktop manager, things work correctly and I see
Bluetooth is available and powered. When I run it using my preferred
fvwm desktop manager, I’m told
No Bluetooth available. Does anybody have any suggestions as to why this might be, and, even better, how to fix it? Thanks for any advice!
I have installed ubuntu 16.04 in hp 245 g6. Initially wifi and bluetooth both were not working, I searched for related question and figured out now my wifi is working but bluetooth is still not working. When I go to bluetooth settings and turns it on, it still shows bluetooth disabled. Please help what should I do?
Good night !
Today I install Ubuntu 19.04. Until now, I’m liking of the system. I have problems of audition, and I use hearing aids. Recently I buy an appliance called Smart connect. This appliance serves to do connect with cellphone and notebook. He is an intermediary of connection. And I saw that Ubuntu 16.04 and 19.04 don’t do connection with this appliance.
So, as Canonical is always improving the system, I want to report a problem so you can work on improving it. Because, other users can be have some problem like my. The system is easy to use. So, I think it’s something for you to think too.
I don’t have sure if this is the correct place for this question.
My regards !
I have a clean-installed Lubuntu-18.04.3.
I have installed pulseaudio-module-bluetooth 1:11.1-1ubuntu7.2 amd64.
I have a new bluetooth USB dongle plugged in, and a bluetooth headset nearby.
I have rebooted.
I have a bluetooth icon showing in my taskbar.
When I click on it I get a menu, including an entry for my bluetooth headset.
The entry has a submenu with only 1 item – “Connect…”.
When I click on that a new small window opens, titled “Connect Device” and an error message “Connection failed – Use the audio menu to connect to this device”.
I’m assuming that “the audio menu” means Pavucontrol > Output Devices, but the only device there is Built in Audio Analog Stereo > Line Out.

I can see lots of questions being asked on this very subject, with unhelpful answers being given.
What is “the audio menu” and how do I get one?
The Bluetooth speaker is visible as a device from my laptop, however if I try to connect to the device through the Bluetooth GUI interface nothing happens. All it does is say “Not Set Up” next to the device prior to and following (after a short loading delay) my attempt to connect.
I have also tried connecting using bluetoothctl from the terminal. This, also, does not work, however it seems to suggest that my laptop is, in fact, able to connect to the speaker, but this connection is simply dropped after a second or two. Below is a screenshot of the output when I try to connect to the speaker through terminal (ignore the first failed pairing attempt, as the speaker had turned itself off after a period of inactivity):
I am able to connect to the speakers with my phone, as well as my Windows 10 OS (dual-boot), thus it seems to be a problem with Ubuntu.
I have also tried using blueman to connect to the speakers, however this also gives an error, a screenshot of which is again linked below:
The model of the speaker is a Harman Kardon Onyx Studio 2, if that’s of any use.
Using the controller with steam and it constantly is disconnecting and reconnecting. Sometimes it takes a few minutes and sometimes its almost instant. Tried un-pairing and re-pairing it. I don’t have any other bluetooth devices to see if it’s just the controller.
