Provide an easy-to-use xrandr interface for MID

https://launchpad.net/ubuntu/+spec/mid-screen-rotation

Conversation focused on the need for a UI widget to allow for general xrandr services for MID. Alberto Milone is working on a python interface for xrandr, which is probably a sensible basis for this tool. Devices with accellerometers or dedicated hardware screen change buttons may benefit from support for hotkey activation of some services.

Discuss the launcher used for Jaunty on Ubuntu MID

https://blueprints.launchpad.net/ubuntu-mobile/+spec/mid-jaunty-launcher

Conversation focused on extending kourou, with identification of specific requirements for implementation in Jaunty. These included finger scrolling, background image support, and various miscellaneous bugfixes.

Applications used in Ubuntu MID

https://blueprints.launchpad.net/ubuntu/+spec/mobile-applications

General review of the core application set for MID usage, and a selection of applications to meet that need. Discussion did not complete within the session, and is expected to continue throughout the week at the Mobile roundables. This is likely to be a repeating review, to ensure that the selected applications are the best fit for the use cases of those available within Ubuntu.

Display Manager for MID

https://blueprints.launchpad.net/ubuntu/+spec/mid-display-manager

Early in the discussion it was determined that supporting a separate display manager would be a fairly high overhead. Solutions considered included looking at how the new gdm might fit, although it has an increasing amount of overhead to support Desktop use cases, and to modify startx to work properly, as startx is a common use case in other contexts as well. Conclusion was to look at enabling proper support for consolekit and policykit in startx itself.

Define what goes into the ship seed on the mobile images

https://blueprints.launchpad.net/ubuntu/+spec/ship-seed-for-mobile-images

Discussion included review of requirements, and identification of specific packages to be included. Further input from other developers was sought to ensure the results would be useful for the widest range of sensible environments. With high probablility, this will mirror the ship seeds used for the Desktop images.

Moblin Overview and Compliance

https://blueprints.launchpad.net/ubuntu-mobile/+spec/moblin-compliance

• Intel provided information as to what Moblin 2.0 Compliance is.
  • Superset of Linux Standard Base (LSB) 4.0 Specification
  • Will provide additional tests to show compliance.

Weighting the benefits of lpia versus i386

https://blueprints.launchpad.net/ubuntu/+spec/lpia-versus-i386

Intel offered insight into the benefits of lpia, and future plans for the platform. As the performance-optimised and power-optimised processor trees develop, there is greater divergence expected, with a strong possibility that the two branches may not remain binary compatible in the future. While lpia has little clear benefit today, it remains useful as a platform for experimentation with various optimisations available. Once the processor families diverge sufficiently, lpia will need to be defined as an architecture for autotools, etc. before which time it remains an experimental x86 branch.

Application switcher for MID

https://blueprints.launchpad.net/ubuntu/+spec/mid-application-switcher

Wide discussion on use cases and requirements for an application switcher, with many good ideas presented for solutions. Consensus developed on the replacement of the Home plugin with a more advanced tool to select the desired application. For best results, such a tool should be coordinated with adjustments to kourou to better handle single-launch of applications.

Mobile Roundtable

These sessions tended to include short reviews of meetings attended the prior day in other tracks, implications for expected future discussions on the Mobile track, and continued review of application selection.

Create ISO images for Ubuntu Mobile and Ubuntu MID

https://blueprints.launchpad.net/ubuntu-mobile/+spec/mobile-iso-images

Conversation focused on benefits: while the implementation is fairly trivial, and there are tools that allow one to convert an ISO to a USB key for booting, it was expected that very few users would be able to directly use a CD to install a system. It was determined to open an idea on brainstorm to understand the support behind the use cases for CD images (distribution at events, ease of sharing and archiving, etc.) is sufficient to outweigh that the majority of end-users would need to use special tools to prepare installation media.

Discuss the mobile seed, and related topics

https://blueprints.launchpad.net/ubuntu/+spec/mobile-team-seed-management

Fairly quick review of the state of the seeds, and how to manage them. Nobody present used the "mobile-dev" set of packages, so that shall be dropped. Seed management will likely move from ubuntu-core-dev to ubuntu-mobile-dev, pending further insight into the results from ArchiveReorganisation. The "mobile" seed, task, and metapackage will be renamed, as part of the effort to subsume the Netbook Remix into Ubuntu itself.

Discussion of UNR issues for Jaunty

https://blueprints.launchpad.net/ubuntu/+spec/unr-handling-jaunty

• UNR (Ubuntu Netbook Remix) based on Clutter 0.6,
  • - Intrepid has 0.8. Its not based on the newest stuff
• UNR needs a new name. (maybe)
  • Name remained Ubuntu-Netbook-Remix
• OEM Has UNR image, Mobile has UMPC that contains most of the UNR packages, but a bit out of date.
• Might not be able to avoid netbook name due to existing brand establishing
  • Was reason for name remaining UNR
• UNR is using moblin-image-creator, but that change is for another day.
• The translations for UNR are hosted in Launchpad, but not currently in langpacks
• UNR has ~43 modified packages, to make apps run at 1024x600, change strings to be smaller, and to make buttons larger and easier to use.
• UNR seed uses additional packages such as desktop-switcher, and diverges from the desktop seed.
• The goal of the UNR seed is to be usable on netbooks on screen, and makes sense on netbooks (i.e. no gimp) + simplicity
• Should GNOME customizations be kept in UMPC?
• UMPC images, current virtual keyboard is cellwriter, but disabled because it was buggy in intrepid.
• UNR launcher needs more work to be finger friendly
• Clutter actually needs 3D, which VMware doesn't support, nor does KVM

Find the right set of images to build for the ARM architecture

https://blueprints.launchpad.net/ubuntu/+spec/selection-of-arm-images

Initial consensus on netbook, live, and alternate images. Some discussion about various bootloaders (uboot, redboot, etc.), and how to handle variance in how ARM hardware boots. Consideration of live images being provided without kernels, so they may be reused for multiple subarchitectures, as kernels take a fair amount of space. Given the wide number of flavours, and initial smaller set will be selected, with flavour-specific teams to focus on other images if desired. Firm decision on Ubuntu Desktop (live), Ubuntu Server (alternate), and a universal netboot image. Kubuntu, Xubuntu, MID, etc. to be deferred for renewed investigation by flavour-specific teams.

Roundtable review of available hardware and device support

https://blueprints.launchpad.net/ubuntu/+spec/mobile-hardware-support

Very little discussion on outstanding issues, or specific hardware that needed support. Participants demonstrated multiple devices on which they had or would like to install Ubuntu. Specific devices demonstrated included: Nokia n770, Nokia n800, Nokia n810, Sharp Zaurus 3200, Sharp D4, Beagleboard, NSLU2, Toshiba N80, Compal Jax10, Samsung Q1 Ultra.

Review and clean up mobile-related specs in launchpad

https://blueprints.launchpad.net/ubuntu/+spec/mobile-spec-cleanup

Lighting review of 75 specifications in 30 minutes, with many determined obsolete or deferred for review at the next UDS. Most specifications were previously completed, but launchpad had not been updated to reflect the status accurately.

Have a selection menu in the mobile images, similar to the CD bootmenu

https://blueprints.launchpad.net/ubuntu-mobile/+spec/gfxboot-like-menu-for-mobile-images

After short discussion it was realised that most of the goals for this effort had already been accomplished by the change in the image building method, and that some others were rendered obsolete by the adsorbtion of Netbook Remix into Ubuntu itself. It was decided not to proceed with a separate effort.

Ubuntu Mobile Setup Wizard

https://blueprints.launchpad.net/ubuntu/+spec/mobile-setup-wizard

The expected leader was not present, so after a late start, most of the conversation was related to questions about oem-config, and how it might be used, and whether it would meet the requirements. It was decided to include oem-setup and test it throughly with Jaunty, with possible UI adjustments if required for lower resolution environments.

Recovery partition

https://blueprints.launchpad.net/ubuntu/+spec/recovery-partition

Create a hildonised ubiquity front-end

https://blueprints.launchpad.net/ubuntu/+spec/ubiquity-hildon

Ubiquity has significant UI adjustments planned for the Jaunty cycle. As most of the MID-specific requirements were more closely related to issues with low resolution than with issues with hildonisation, conversation focused on a review of the current UI to discuss which elements did not fit in 480 vertical pixels. The results are expected to feed into the general ubiquity redesign, with no specific work being done on a separate front-end.

Packaging of the Poulsbo drivers

Discussion of how to repackage what we are provided by Intel so that Poulsbo graphics cards can be used on Intrepid with no fuss -- this includes putting the packages into a PPA, and repacking things.
