I have Ubuntu 18.04.3 LTS running on a LG gram computer and I decided to turn off my Bluetooth today in order to unpair something. Now I cannot turn it back on. This laptop originally came with Windows 10, so I am sure the Bluetooth card in my laptop has some weird stuff where it can only turn on using Windows 10 OS. So I have been searching for an easy solution for a couple hours or so and I could not find an easy solution. I am considering just going down to the store and buying a dongle. Anyway I can resolve this issue without doing that? Thanks.

Output for "lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue" is:

I did get a Bluetooth dongle and it is working for me, but perhaps we can still figure this out. Thanks.

  • How did you turn the bluetooth off? – Charles Green Jan 11 '20 at 17:37
  • Settings app, went to bluetooth and switched it to off. – Henry Jan 11 '20 at 17:39
  • Go to Settings app, go to bluetooth and switch it on? – waltinator Jan 11 '20 at 18:06
  • That does not work. It says no bluetooth found as if I don't have a bluetooth card in my laptop. – Henry Jan 11 '20 at 18:19
  • Please [edit] your question and add output of lspci -knn | grep Net -A3; lsusb; dmesg | grep -i blue terminal command. – Pilot6 Jan 11 '20 at 19:12
  • The edit is now added – Henry Jan 11 '20 at 19:41
  • The output is wierd to me. 1. You have an Intel 8265 Wi-Fi device that should have BT inside. 2. dmesg shows that a Broadcom BT device is found and can't load firmware. 3. There is no Broadcom 19ff-0239 device in lsusb. Regarding Broadcom firmware see https://askubuntu.com/questions/632336/bluetooth-broadcom-43142-isnt-working/632348#632348 – Pilot6 Jan 11 '20 at 19:47
  • I am connected to the internet through USB tethering on my phone. Not sure if that is causing any strangeness in what you are seeing. I will read your link and see if that helps thanks. – Henry Jan 11 '20 at 19:51
  • BTW that thread is over 4 years old... but I see the answer was edited in 2019. Is this up to date? – Henry Jan 11 '20 at 20:17
  • It is up-to-date except the download links. – Pilot6 Jan 11 '20 at 20:57
  • It seems like it would solve my problem, but its a little too complicated for me. My new bluetooth dongle works fine. Sorry for not following through with this though. – Henry Jan 11 '20 at 22:15
