Depending on your computer, you might have to install some specific vendor drivers and/or dedicated programs.

Audio

Audio ALSO mixer

apt-get install alsamixergui pavucontrol


Bluetooth headset manager

Drivers setup

Pulse-audio + bluetooth requirements: 

apt-get install paprefs paman padevchooser
apt-get install pulseaudio-module-bluetooth*

Low quality sound driver: 

apt-get install bluez-btsco

High quality sound driver: 

apt-get install bluez-alsa

Restart your computer.


Pairing

Pair your audio device using the User Interface (blueman). Xubuntu > System settings > Bluetooth manager

... Then note its bluetooth HW address.


Declare audio device

Create a bluetooth configuration file. 

vim ~/.asoundrc

Insert 

pcm.btheadset {
        type bluetooth
        device 00:02:5B:02:56:E0
        profile “auto”
}

Replace "00:02:5B:02:56:E0" by your real hardware address

Restart your computer.


Auto-connect

Edit your bluetooth settings: 

sudo vim /etc/bluetooth/audio.conf

Under [general] add and un-comment: 

[General]
Disable=Socket
AutoConnect=true


Edit your Pulse-audio settings: 

sudo vim /etc/pulse/default.pa

Line 42, add: 

load-module module-switch-on-connect

Restart your computer.


Usage

You should see your device from the bluetooth manager.

Xubuntu > System settings > Bluetooth manager


Your bluetooth device should appear in PulseAudio Volume control.

  • Go to the configuration tab
  • In the bluetooth headset section, select profile High Fidelity Playback A2DP
  • Go to playback tab
  • Set your headset as default output
  • Play your music / video

Troubleshouting

If your device does NOT appear in pulseaudio, try to:

  1. Pair the bluetooth device
  2. Reset pulseaudio service:
    pulseaudio -k

Then the headset should appear!


Sources

Ubuntu official help:

Other thread:



Nvidia graphical driver

This is required to manage many screen on Nvidia chipsets.

!! As of now (November 2013) Ubuntu cannot work with Nvidia Optimus technology !! You have to disable it from your bios (under video > Optimus).

Nvidia driver: 

apt-get install nvidia-current-updates

Reboot after installation. Then you should be able to configure your screens.
