I am running Ubuntu 14.04 on my laptop. The laptop's Bluetooth seems to work fine as I have a remote Logitech keyboard that I have paired with it that works flawlessly.
My problem is with my Nexus 5X which I would like to pair with the laptop to exchange files. The laptop appears to recognize the 5X and correctly identifies it in the Bluetooth devices as a 5X. In Bluetooth settings I can watch when I try to connect and the connection widget goes from "off" to "on" and then immediately back to "off". I see the same behavior on the Nexus 5X.
If I connect via USB, the laptop connects fine and I can transfer files. I can connect my 5X and transfer files via Bluetooth to my windows laptop.
Any ideas what I may try next to make this work?
