I'm using ubuntu 18.10. In the past I probably made a change for my bluetooth to not start on startup but I do not remember the change. Now, I want to restore it back to normal but I couldn't find a way. Every time I start-up my system the bluetooth icon is not even appearing. When I start it from the applications it says daemon not running etc. I checked "blueetoth/main.conf" but "AutoEnable=true" exists. If I do
sudo service bluetooth start
it works but when I restart my computer, the problem is back again.
sudo rfkill unblock bluetooth
This didn't solve the problem, too.
