Many Ubuntu developers are also prolific free software developers and contribute to other projects, notably to Debian.
Canonical employee Scott James Remnant developed from scratch Upstart, a modern event-based init daemon. Upstart is now default init system for Ubuntu, Fedora, Meamo, Chrome OS and Frugalware Linux.
- initramfs-tools was originally written by Jeff Bailey for Ubuntu, and later became Debian's default initramfs system.
The dpkg Breaks field was implemented by Ian Jackson for Ubuntu.
dpkg triggers were implemented by Ian Jackson for Ubuntu.
- Ubuntu developed a simplified front-end to apt called gnome-app-install (originally written by Ross Burton, but then developed for some years by Michael Vogt of Ubuntu).
- Ubuntu developed a system to notify users about package updates (update-manager, update-notifier).
- Ubuntu is heavily involved in the development of apt, python-apt and Synaptic.
- An application to view and install deb packages called gdebi was developed by Ubuntu.
Aptdaemon allows normal users to perform package management tasks, e.g. refreshing the cache, upgrading the system, installing or removing software packages.
computer janitor The app that was formerly known as "Systemcleaner application for ubuntu"
Ubuntu developers have made a number of important contributions to debian-installer:
- debootstrap progress via debconf, and a good deal of what became the first-stage task installer glue
- base-installer kernel selection refactoring and test suite
- much of udev support and devfs path removal
- pcmciautils support
- chunks of debconf maintenance effort such as the progresscancel and escape capabilities
- reserved username checks
- some of rescue mode
- translation handling work in cdebconf that saved about 20MB of run-time memory
In addition, we developed a custom graphical installer, Ubiquity, which uses debian-installer for many of its back-end tasks.

Software Freedom Day
Software Freedom Day (SFD) is an annual worldwide celebration of Free Software. SFD is a public education effort with the aim of increasing awareness of Free Software and its virtues, and encouraging its use.
The primary sponsor from the start was Canonical Ltd
Go Open Source
Go Open Source is a South African campaign to create awareness of, educate about, and provide access to open-source software. It is important, once awareness of OSS has been created, that interested parties have the ability to gain access to the software and services, and that they have access to additional resources for support and training. It ran from May 2004 to May 2006.
The campaign was launched by Mark Shuttleworth on behalf of Canonical, the CSIR Meraka Institute, HP, and the Shuttleworth Foundation.
Canonical sponsor a range of conferences, events and groups including:
The implementation is including some improvements like:
- Dropping the insecure XDMCP model that allowed you to even take screenshots from a networked X stream
- New sound implementation based on alsa
- A new way of handling local block devices as well
- New printserver to replace the unlicensed lp_server shipped with former ltsp versions
- Deep integration with the GNOME Desktop
- An LTSP specific display manager called LDM which simply acts like a graphical ssh client
- Multiple appserver support out of the box
- Deep integration with the debian installer and the Ubuntu alternate CD for a comfortable out of the box install for LTSP servers
- Deep integration with the Ubuntu hardware autodetection mechanisms dropping the need for configuration of thin clients in most cases
- Automatic swapping over the net if ram on a client is low
- Dropping the need for nfsroot resulting in massive client speedup through a unionfs/aufs mount on top of an nbd blockdevice that uses squashfs
Debian joined the development after 6 months supplying large contributions
Fedora recently picked up the Ubuntu code as well with the Fedora 9 release
Gentoo is working on an LTSP5 implementation based on this code as well.
OpenSuSE uses the existing LTSP5 code to implement a similar setup wrapped into their kiwi liveCD build scripts.
The upstream development which was led by ubuntu for 2.5 years was switched to a completely new model of cross distro team effort in October 2007; each participating distro has an upstream development contact in the ltsp-upstream team through which they can directly submit code to the launchpad bzr trees.
- Fixes and quirks for variety of issues in -intel, -ati, other drivers, and the X server.
- Participated with Fedora (and later Mandrake) in the early development of the Xrandr-1.2 gnome-display-properties capplet (subsequently taken upstream), contributing significant QA and stability bug fixes, and a revert dialog.
- X-Kit, a python library for parsing/modifying xorg.conf files. Used in EnvyNG and elsewhere through Ubuntu.
System Settings, the KControl replacement, was maintained and pushed into KDE 4 by Kubuntu developers.
printer-applet, part of KDE 4.1, was written by Jonathan Riddell
guidance-power-manager, part of KDE extragear, was written by Kubuntu developers.

Ubuntu led the successful charge to got AppArmor into the 2.6.36 kernel.
"Canonical is committed to AppArmor's development and to that end in order to do it properly it needed to go upstream," Pete Graner, Manager of the Ubuntu Kernel at Canonical told InternetNews.com. "I wouldn't call that a victory, it's the right thing to do."
Launchpad is a set of Web services to help software developers collaborate. it has been recently open sourced.
PowerNap & PowerWake
PowerNap is a configurable daemon that will bring a running system to a lower power state according to a set of configuration preferences. It acts as a sort of "screensaver" for servers, watching the process table for activity rather than the keyboard or mouse. PowerNap will run $ACTION when none of $PROCESSES have executed for some number of $ABSENCE seconds. For instance, PowerNap can automatically "pm-suspend" a system if no instance of "kvm" runs for some contiguous block of "300" seconds.
Byobu is an elegant enhancement of the otherwise functional, plain, practical GNU Screen. Byobu includes an enhanced profile and configuration utilities for the GNU screen window manager, such as toggle-able system status notifications
Ubuntu Font Family
The Ubuntu Font Family are a set of matching new libre/open fonts in development during 2010-2011. The development is being funded by Canonical on behalf the wider Free Software community and the Ubuntu project. The technical font design work and implementation is being undertaken by Dalton Maag. Members of the Ubuntu core development team are packaging the font in .deb format. The font was released under a libre-licence and is now packaged in Ubuntu 10.10.

BAMF Application Matching Framework
Removes the headache of applications matching into a simple DBus daemon and c wrapper library. Currently features application matching at amazing levels of accuracy (covering nearly every corner case).
A small little library that was created by pulling out some comon code out of indicator-applet. It passes a menu structure across DBus so that a program can create a menu simply without worrying about how it is displayed on the other side of the bus.
Quickly helps you create software programs (and other things) quickly. You can select from a set of application templates and use some simple commands to create, edit code and GUI, and publish your software for others to use.
TestDrive is a project that makes it very easy to download and run the latest daily Ubuntu development snapshot in a virtual machine. Actually, it can be configured to download and run any URL-access ISO in a virtual machine. But the primary goal is to provide a very simple method for allowing non-technical Ubuntu users to test and provide feedback on the current Ubuntu release under development.

Ayatana is a collective effort to improve the user experience of software in and for Ubuntu. It encompasses a number projects started by Canonical and is open for feedback, ideas and initiatives from the community. Activities reach from problem definition, research and conception to implementation. The focus of the project is to improve the perception and presentation of information in the desktop, hence the name; the Buddhist term for a sense base or sense sphere. Specific areas of interest that take priority over everything else are: notifications, indicators, window management, launcher, places, settings and menus.
