Changes for this release (compared to Cosmic Cuttlefish)
Ubuntu Studio Installer (formerly Ubuntu Studio Metapackage Installer) has been updated and adapted to:
- Install metapackages or other items not installed (opted-out) during installation.
- Install Ubuntu Studio's configuration and/or metapackages on top of an existing Ubuntu (flavor) installation.
This means Ubuntu Studio's tools and configuration can be used on any official flavor of Ubuntu.
NOTE: Derivitives of Ubuntu (Linux Mint, Kali Linux, etc.) are not supported.
- Users will find new default themes for the Desktop Environment, Window Manager, and Icons.
- GTK Theme: Materia

Known Problems
- There is an issue where Ubuntu Studio will freeze at boot when run inside a virtual machine. However, since Ubuntu Studio is not designed to run in a virtual machine for performance reasons, we do not support this method of using Ubuntu Studio. If you wish to try Ubuntu Studio, burn it to a DVD or run it from a USB drive.
A problem has been discovered related to this bug in xfce4-volumed where a user's hardware volume keys will not respond after restarting PulseAudio, such as when starting and stopping Jack. Only workaround is running the following in a terminal:
killall xfce4-volumed && xfce4-volumed
Ubuntu Studio uses the same XFCE desktop environment as the official Xubuntu release, and thus, may be affected by some of the same issues. This is also true of the core packages of the mainline Ubuntu release. You can see their release notes here (Xubuntu) and here (Ubuntu)
- Timidity (not installed by default) has been known to cause problems with audio configurations on Ubuntu and will lock-up ALSA.
Support
Ubuntu Studio Disco Dingo (19.04) will be supported for 9 months until January 2020. If you need Long Term Support, it is recommended you use Ubuntu Studio Bionic 18.04 with the Ubuntu Studio Backports PPA instead.
