My bluetooth is not not working on ubuntu 14.04. I am not sure whether my bluetooth adapter is not getting recognized or necessary drivers are absent. I tried many things but no luck. I found that similar issue was resolved on question. [My bluetooth is disabled in Ubuntu 14.10

Following is the output of necessary commands.

dexter@dexter-Lenovo-G50-80:~$ lspci -nnk | grep -iA2 net
