Unable to activate Bluetooth in Ubuntu 17.10 (used to work flawlessly)

  • 772

I use Bluetooth for my headphones and it used to work more or less in Ubuntu 17.10 (had to redo the pairing process sometimes but then it worked out). After I installed Dash-to-Panel-Extension for GNOME for whatever reason the Bluetooth adapter turned off and won't turn on again.

In my Bluetooth settings it says 'Bluetooth Turned Off'. I can push the button to turn it on, but nothing happens.

Also I can press the "turn on" button in the Panel, but nothing happens.

Things I've tried:

  • Deactivating Dash-to-Panel Extension (and restart computer)
  • sudo service bluetooth start

  • sudo apt-get install --reinstall bluez

  • reinstalled all Bluetooth components with 

    sudo apt install bluez bluez-cups bluez-obexd gnome-bluetooth indicator-bluetooth libbluetooth3:amd64 libgnome-bluetooth13:amd64 pulseaudio-module-bluetooth

  • Different variations of turning the bluetooth switch of my laptop off and on and restarting

  • rfkill list all

    Output:
    enter image description here
    (so it seems not to be blocked)

  • lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue

    Output:
    enter image description here
    (again seems not to be blocked)

  • bluetoothctl list
    Output: enter image description here

Now I'm running out of ideas. Are there any other approaches?

  1. As loge as it's not your hardware problem an upgrade will fix it (probably) so consider upgrading to latest stable release.

    Note: before you do so make bootable device and check if it's not your hardware problem by running a live Ubuntu OS. if Bluetooth works in live mode consider upgrading to latest LTS release
    it will fix the issue. last time i had the issue i done the something it worked for me.
