  • It doesn't appear that you have a bluetooth device installed

  • @Jeremy31 Had Xubuntu 16.10 before upgrading and everything used to work fine except for bluetooth audio

    Going to follow this thread. I'm using 17.10 on my XPS 9560 and BT will randomly stop working. I can usually reboot 2-3 times and it'll suddenly work again. No idea why and can't find anything helpful out there.
