Hope you don't mind, but I'm having much the same problem, so I'd like to put it here in this thread
A sad story: home from holiday in Spain, I want to send some photos from my mobile to this laptop. Worked before the holiday. Bluetooth won't switch on on the laptop.
I followed these instructions, which worked for me previously:
Quote:
1. Start the bluetooth daemon
Go to your terminal and type :
sudo /etc/init.d/bluetooth start
2. Reinstall packages
If this doesn't work, go to your terminal and type :
sudo apt-get purge blueman bluez-utils bluez bluetooth
sudo apt-get install blueman bluez-utils bluez bluetooth
Then run :
sudo /etc/init.d/bluetooth start
Purging bluetooth had a strange effect: System Settings was lost! The Ubu 16.05 install was broken, though still running
I decided to upgrade to 18.04 from the software manager. Took a while, but it got there.
Seems now, the reason bluetooth will not start is because there is no bluetooth adaptor (see screenshot). Maybe it broke while I was on holiday, but the the laptop was unplugged and off.
Is there any way to get the bluetooth adaptor going again?
Hmmm... we updated at the same time. I found my other Bluetooth adaptor, which comes up at least. I chalked up the failure I report in this message to bad hardware.
I had to load the bluetooth modules explicitly. If yours are modular you can check whether they are loaded. I have to run
Code:
modprobe bluetooth
modprobe bnep
modprobe hidp
modprobe rfcomm
pedro@pedro-school2:~$ modprobe bluetooth
pedro@pedro-school2:~$ rfkill list
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
This is from my newer laptop, running Ubu 16.05. Bluetooth works fine on this laptop, as it did on my other laptop before my holiday!

AND: it worked about a month ago, before my holiday. Something in an update rocked the boat. However, I did the same updates on the newer laptop and it still works.
It's a mystery! Someday, some update will make it work again!
