Contributing Blueprints

Blueprint Completion Priority Status/Description
desktop-r-arm-input-sensor-drivers
75% of 12
Undefined Enable various input drivers to provide sensor access on ARM devices (tablets and phones). This includes the following: - camera [PRIORITY] - wifi [PRIORITY] works - bluetooth [PRIORITY] works - touch [PRIORITY] works (single touch) - accelerometer - GPS - compass - NFC - Telephony
desktop-r-arm-reduce-footprint
89% of 9
High On arm, we are going to keep the same desktop experience than the desktop one. Streamlining the image removing some packaging and very few light tweaks.
desktop-r-reduced-power-ram
98% of 42
High In the past few cycles, we saw that our desktop took more and more RAM to run the full session. Also, more daemons mean more interruptions on the CPU, and less battery file. We will get services to not run when not needed and work on improving the code of those components to consume less resources
hardware-r-arm-power-measurement
100% of 9
High A discussion of best practices for measuring and reporting power consumption on low power devices. This will include software tools, lab testing environments, and tools for troubleshooting problems.
foundations-r-arm-usb-creator-fastboot-support
80% of 10
Medium With the R release we want to be able to flash ubuntu onto unlocked fastboot based android devices. The image build system will provide img files for this. To make the actual flashing procedure as easy and safe as possible, this functionality should be integrated into usb-creator which already deals with writing images to devices.
desktop-r-onscreen-keyboard-review
100% of 5
Medium Review of the onscreen keyboard options, their pros and their cons and what work will be needed for Ubuntu in the next cycles.
foundations-r-arm-boot-resume-speedup
62% of 13
High A discussion of how to measure boot & resume time for ARM devices, tools for measurement, and what things can be done to improve the performance of each.
foundations-r-improve-cross-compilation
23% of 13
High We now have cross-compilers in Ubuntu, and interesting cross-compilation targets in Ubuntu. It's time to step up the best practices around them and make sure we have a good working solution for the packages that are part of the image.
desktop-r-tablet-desktop-convergence-divergence
60% of 5
High Now that we have the Nexus 7 as a reference device, it is becoming obvious that there would be certain system policies that might be applied to make Ubuntu Desktop behave better on a tablet. For example, it is common on tablet devices to press the power button and expect to instantly suspend the machine, instead of prompting the user for the desired action. We need to create a plan on how to identify and manage these potential policy differences.
foundations-r-android-image-builds
78% of 9
High Devices which ship with Android require OS images to come in a particular ROM format. Ensure that generating these images is well-supported in the cdimage.ubuntu.com pipeline.
