I cannot find a Bluetooth device to connect to, as a result, blueman does not work, and I can't figure out what the problem is.

The weird thing is I cant even find a bluetooth device to begin with, as you can see down here, results of all hcitool dev or rfkill does not contain anything about a bluetooth device like hci0.

I'm using Lubuntu 18.04 LTS and My Laptop is Asus X555L the result of the related commands are given below:

$rfkill list 
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

$hcitool dev
Devices:

$lsusb

and when I run blueman-manager from terminal, I get this in the logs:

SetAdapter (/usr/lib/python3/dist-packages/blueman/gui/DeviceList.py:271)
No such adapter 

Also, almost all buttons are inactive and I can't do anything in the bluetooth manager. all buttons in bluetooth manager are inactive

I don't know what the problem is, the bluetooth device worked on my previous linux OSes and Also on my windows.

I was able to solve this problem by looking at the launchpad bugs in this link and installing dkms package along with a ar3011-dkms package that was suggested in the link (although I didn't need to install it manually and installing dkms using apt-get did it automatically) and then restarting my laptop.

And now Bluetooth is working correctly and as expected.

I know I am a little late to the party but if the bluetooth service is running and rfkill is not displaying your bluetooth you may need to ask the kernal to register it.

open up your kernal options and add to the end pci=nomsi restart your computer and you should have bluetooth registered. enter image description here
