[Bug 1259237] Re: Hybrid graphics enablement in 12.04.4

 

This bug was fixed in the package nvidia-graphics-drivers-304 -
304.116-0ubuntu0.0.1

---------------
nvidia-graphics-drivers-304 (304.116-0ubuntu0.0.1) precise-proposed; urgency=low

  * New upstream release (LP: #1259237):
    - Improved compatibility with recent Linux kernels.
    - Updated the NVIDIA OpenGL driver to write temporary files to
      $TMPDIR if it is set, instead of unconditionally writing to
      /tmp (LP: #1212425).
    - Updated a fallback of writing temporary files to $HOME/.nvidia
      to use $HOME/.nv instead, as the latter path is already used
      for other NVIDIA driver related files.

  * debian/substvars:
    - Add support for lts flavours up to saucy.
  * debian/templates/control.in:
    - Depend on lib32gcc1 [amd64], libc6-i386 [amd64]
      (LP: #1236945).
    - Drop lpia.
  * debian/templates/dkms.conf.in:
    - Drop patch for Linux 3.10.
  * debian/rules:
    - Blacklist the opposite flavour.
    - Blacklist kernel modules from the other flavours.
    - Add the download-sources target.
  * debian/templates/nvidia-graphics-drivers.dirs.in,
    debian/templates/nvidia-graphics-drivers.install.in,
    debian/templates/nvidia-graphics-drivers.override.in,
    debian/templates/nvidia-graphics-drivers.postinst.in,
    debian/nvidia-autostart.desktop.in,
    debian/ubuntu-nvidia-settings.desktop.in:
    - Remove nvidia-settings icon, desktop file, and autostart file.
      This is all provided by nvidia-settings now.
  * debian/templates/nvidia-graphics-drivers.prerm.in,
    debian/templates/nvidia-graphics-drivers.install.in,
    debian/templates/nvidia-graphics-drivers.postinst.in:
    - Disable glamoregl.
    - Do not update gmenucache any more.

  [ Andy Dick ]
  * debian/templates/nvidia-graphics-drivers.preinst.in:
    - Attempt uninstallation of any existing .run file
      installation before installing Debian-packaged
      driver.
  * debian/templates/nvidia-graphics-drivers.postinst.in:
    - Add libcuda.so symlinks in /usr/lib*.
  * debian/rules:
    - Conditionalize the copying of Makefile.kbuild to
      Makefile. This adds support for newer drivers,
      while maintaining support for packaging older drivers.
    - Avoid extracting unnecessary .run files. The 64-bit
      package needs both the 32- and 64-bit .run files, but
      the 32-bit package does not. Change the unpackaging
      rules to unpack only the native package by default,
      and only unpack the 32-bit x86 package on amd64.
      Also, instead of changing the .run file permissions
      to ensure that the .run file is executable, just call
      it as an argument to sh.
    - Don't assume that extracted files are writable.
      The package contents extracted from some .run file
      installers may not have write permissions enabled.
      To work around this, move files instead of copying
      them to a temporary location before running sed
      scripts, and add force flags to applicable commands.

Bug description:
  SRU request:

  Please accept the following packages in precise-proposed.

  lightdm
  nvidia-prime
  nvidia-graphics-drivers-331
  nvidia-graphics-drivers-331-updates
  nvidia-graphics-drivers-304
  nvidia-graphics-drivers-304-updates
  nvidia-graphics-drivers-173
  nvidia-settings
  screen-resolution-extra
  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-resolution-extra, and nvidia-settings.
  * 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.
