Ubuntu

each time the OS updates the desktop, my bluetooth gets disabled and stops working.

Asked by Stephen McCreery

I have Ubuntu 16.04 and use blue-tooth to connect the mouse and my "sound system" (due to hearing loss, I have hearing devices that connect to the computer through Unitrons Udirect 3 which is a blue-tooth headset that is paired to the hearing devices in the ear).
When Unity gets updated, the sound portion of the blue-tooth system gets disabled and cannot find the blue-tooth adapter. That adapter is built in to the system board of the laptop.
How do I reenable that when this happens?
