I have multi-booted Ubuntu 14.04 alongside the pre-installed Windows 8.1 on my uefi-enabled HP Envy 15 Notebook. My WLAN card is a combo card, Ralink3290.
The problem is that my wifi works just fine both in Ubuntu and Windows, but I cannot get the bluetooth to work in Ubuntu. I have no problem with the bluetooth in Windows whatsoever. But in Ubuntu, the Bluetooth option in System Settings always shows "Bluetoth Adapter Not Found". The option to enable it is also greyed out. Also, I cannot enable it manually through my keyboard button. Seems that something is wrong with the adapter drivers.
Being a newbie in linux environment, I am not sure where the problem lies. I have gone through other posts, but did not quite get the solution. I tried installing Blueman and all, but did not work for me. I also installed the driver from Mediatek, but during installing it, I got an Error 2 response, which I am not sure why.
Could somebody please help me out?
