Bug Description
SRU request:
Please accept the following packages in precise-proposed.
lightdm
nvidia-prime

nvidia-settings

bbswitch
[Rationale]
This is the result of the HWE effort to bring power management to systems with NVIDIA Optimus.
[Impact]
Without this work, we keep both GPUs on all the time, thus heavily impacting on battery life. Thanks to this work, it is now possible to easily disable the discrete card when raw power is not needed.
Furthermore nvidia-prime has better hardware detection now, and won't try to enable hybrid graphics on desktop systems any more.
As for the technical details:
* bbswitch is a backport of the package that now lives in main in 14.04.
* The actual work happened in lightdm, nvidia-331, nvidia-331-updates, nvidia-prime, screen-
* nvidia-settings now replaces all the different nvidia-settings flavours, so as to reduce the maintainance effort. I patched the app so that it checks the driver version (at runtime) and doesn't expose features that older driver releases do not support.
* nvidia-331 and nvidia-331-updates replace 319 and 319-updates. These are the new LTS releases by NVIDIA.
* nvidia-304 and nvidia-304-updates recommend the new nvidia-settings, include a security update, and build against the upcoming Linux 3.11 (lts-saucy).
* nvidia-173, in addition to being compatible with Linux 3.11 (lts-saucy), also introduces transitional packages for 173-updates, as it doesn't make sense to maintain a separate -updates flavour any more.
[Test Case]
After installing the update, users should be able to boot the system as usual, with no regressions of any kind.
* Systems with a single NVIDIA card: nvidia-prime will detect the hardware and do nothing at all on unsupported systems (such as the one card use case, or the desktop use case)
* Systems with NVIDIA Optimus: nvidia-prime will preserve its previous behaviour by leaving both GPUs on. Users can launch nvidia-settings and switch to the power profile that they need.
[Regression Potential]
Low. The new features are enabled only if the user manually selects them.

Hello Alberto, or anyone else affected,
Accepted nvidia-settings into precise-proposed. The package will build now and be available at http:// launchpad. net/ubuntu/ +source/ nvidia- settings/ 331.20- 0ubuntu0. 0.1 in a few hours, and then in the -proposed repository.
Please help us by testing this new package. See https:/ /wiki.ubuntu. com/Testing/ EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.
If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed. In either case, details of your testing will help us make a better decision.
Further information regarding the verification process can be found at https:/ /wiki.ubuntu. com/QATeam/ PerformingSRUVe rification . Thank you in advance!
