Another vector for installing Ubuntu Studio is to "upgrade" from a current Ubuntu install. While it is not difficult it will require some additional modifications of various configurations. Also of note, not all packages need to be installed. One can selectively "upgrade" various components of the Ubuntu Studio meta-packages.

Full Upgrade

To fully "upgrade" a plain, vanilla Ubuntu install to Ubuntu Studio involves installing packages and modifying configurations.

Installing Packages

To install all required Ubuntu Studio meta-packages, enter terminal & type in:

 
sudo aptitude update && sudo aptitude install ubuntustudio-desktop ubuntustudio-audio ubuntustudio-audio-plugins ubuntustudio-graphics ubuntustudio-video linux-rt

After updating the package list, this will install the following packages:

• Real-time kernel - installs the real-time kernel for low latency
• audio meta-package - install all the Ubuntu Studio audio packages
• graphics meta-package - install all the Ubuntu Studio graphic packages
• video meta-package - install all the Ubuntu Studio video packages
• desktop meta-package - install the Ubuntu Studio desktop, menu and theme

Configuration Modifications

These additional modifications will be required. Note: installing Ubuntu Studio from DVD as a fresh install does not require manual configuration modifications since they will already be configured.

Audio Group

Add yourself to the audio group. If it doesn't exist, create it and add yourself to it.

limits.conf

Open the /etc/security/limits.conf file,

sudo gedit /etc/security/limits.conf

and make sure it says:

@audio - rtprio 99
@audio - nice -19
@audio - memlock unlimited

Selective Upgrade

• Optional: Change the theme to UbuntuStudio. In the Ubuntu menu, select System -> Preferences -> Appearance -> Theme and select UbuntuStudio from the list of themes that is presented to you. Then select System -> Administration -> Login Window, enter your password, and select UbuntuStudio in the list of Login Window themes that is presented to you in the Local tab.

Note: This installs a complete system. If you only want an audio, graphics, or video platform, remove the other respective packages.

temporary information for updating: (do not delete)

• -rt kernel
• limits.conf
• audio group
• jack vs. pulseaudio (configuration?)
