- Decision for applications by default. The proposed was not changing any of the default apps unless they are no longer maintained.
- More icons and artwork.
- Improvements to the general translation process of Ubuntu, automatic checking for translations.
- Ubuntu Youth team: improve documentation, get regular events and meetings going, regular reports.
- Xubuntu: 12.04 improvements, more testing activities, improve screen-locking, more artwork, more plans for contributors, and automated testing.
The biggest change for AskUbuntu which was discussed was translations. Also many ideas were put forward to improve documentation to get better quality on AU.
- The Ubuntu Women's project plans the "Career Days" to get more people involved. Also will they collaborate with the Full Circle magazine.
- We invited a speaker from LEGO who gave a brilliant talk about their community work. Besides inspiring, we'll be able to draw some insights from there for our work.
- Another inspiring talk came from a design agency that talked about co-creation. They gave insights how co-creation can happen in different phases of product design, such as defining the problem, generating ideas
or customizing in the end.
- This morning we had a group discussion with designers and community members on how to approach the creative process. We listed examples of what did work and what didn't in the past and came up with an action to explore to possibility to use an existing co-creation platform for a pilot project.
- We are continuing the work on stability and bug fixing on Unity, particularly in the performance area (both desktop and for games).
- We are going towards delivering automatically the latest work of Canonical upstream on a daily basis in the development cycle. This will be conditionally delivered to the distro after some automated test results to ensure we won't degrade the user experience.
- One workspace by default is under discussion, with an easy way to add more workspaces if needed.
- Installing all available quality scopes and lenses by default to provide the best search experience on an operating system is another one of our target.
Stay on GNOME & GTK 3.6 and update some selected platform components (glib, gvfs, dconf, python-gobject)

- Use gstreamer 1.0 by default (demote 0.10)
- Implement network connectivity checking
- Continue improving our testing
- Keep the regular automatic testing
- Clean up the packaging
- Track the new upstream series

- 13.04 Kernel Version - v3.8
- Upon review of the predicted upstream kernel release schedule, we will look to target the v3.8 kernel for the Raring Ringtail 13.04 release. There were also discussions that the device tree work available in v3.8 might lead to the possibility of beginning to move to single kernel zimage for some of the separate arm kernel flavors we are carrying (eg highbank, armadaxp).
- Nexus 7
- Kernel Support and Maintenance - Discussions were held around the current support and maintenance model of the Nexus 7 kernel which is a v3.1 based Android kernel that has been packaged for Ubuntu. This kernel will be not be officially supported and remain in the Universe pocket. The git repository will be moved to the hwe landing directory on kernel.ubuntu.com/git
- Power Management - A review of current investigation work done on the Nexus 7 and steps moving forward. This included a presentation of tear down and analysis of the device. Going forward, work is being done to investigate the most reliable and accurate means for measing power consumption on this device. Power management tests for the Nexus 7 will also be created to help determine areas and applications needing improvements with regards to power management.
- Kernel Community
- Community interest in PowerPC has risen. The owernship and maintenance of the PowerPC kernel flavor has been handed over to the community. Ben Collins will lead the effort here.
- The Ubuntu Studio community has also steppeed forward to continue to help maintain the lowlatency kernel.
- LTS Enablement Stack
12.04.2 will be the first LTS point release to ship a newer enablement stack by default. Discussions took place to review the existing policies set in place as well as come to a decision on outstanding items. (Summary)
- Iso's will now be automatically 'smoke' tested before general release. More post-installation tests, and in general more automated testing will occur on images
- Rather than milestones, a bi-weekly cadence of testing will occur with the goal of assuring good quality throughout the release cycle.
- Reports / Dashboards
- Summary and high level as well as technical information will be made more available and try to be used to drive testing efforts during the release.
AutoPilot / Xpresser / UTAH
AutoPilot has been expanded to support gtk and other non-qt applications. In addition, xpresser will be integrated into the tool to allow for even more options for functional testing. UTAH continues to be the harness to tie this testing together. Workshops and sessions on these tools were held during UDS.
- A testing contest and evening event was held for autopkg tests. In addition preliminary sessions for growing and advancing this form of automated testing was held.
- Hardware Testing Database
- A preliminary database will be created and initial ideas for utilizing the data, people and machines for targeted testing will be explored.
- We will create more GNOME/desktop related tests and push them to upstream.
- In this cycle we'll try to make our jhbuild setup in jenkins grow notifications and actually get used by upstream.
- We will research testing technology to simulate hardware devices such as monitors or MTP players, so that you can write tests for those.
- Application Confinement
AppArmor LXC support
- Juju Charms
We are going to help with formalizing Charm security best practices. (Blueprint)
