ubuntu-drivers install --gpgpu should use a DKMS fallback when no linux-modules-nvidia package is available

This bug was fixed in the package ubuntu-drivers-common - 1:0.7.6

  * gpu-manager.c:
    - Drop prime_is_action_on() (now that it isn't on/off any more)
      and update the description.
  * UbuntuDrivers/detect.py,
    UbuntuDrivers/kerneldetection.py,
    tests/ubuntu_drivers.py,
    ubuntu-drivers:
    - Provide DKMS fallback for the "install --gpgpu" case
      when no linux-modules-nvidia are available for the driver
      and for a specific kernel (LP: #1843796).
      We have new tests to cover this scenario now.
    - Show provider of kernel modules in list --gpgpu
    - Fix linux metapackage detection.
      This was meant to be driven by the latest kernel version
      But it was only partially implemented.
      Complete the implementation and update the relevant tests.

  * gpu-manager.c:
    - Enable power management in NVIDIA on-demand mode:
      The NVIDIA driver can suspend the GPU when it's being used as a
      PRIME render offload source and it isn't actively being used.
      disable_power_management() sets the NVIDIA GPU's power/control
      mode to "on", which prevents the GPU from suspending when it
      might otherwise be possible to do so.
    - Increase string storage on stack for path names. This fixes
      the warnings that gcc emits when building up path names.

This bug description doesn't fit the SRU template; please fix?

An upload of ubuntu-drivers-common to bionic-proposed has been rejected from the upload queue for the following reason: "Includes a bunch of (hopefully!) non-functional whitespace changes. Changelog links to LP:# 1819207, marked as Won't Fix, and doesn't match the description in the changelog.".

Hello Alberto, or anyone else affected,

Accepted ubuntu-drivers-common into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/ubuntu-drivers-common/1:0.5.2.4 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 on 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-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

I have tested this package in bionic-proposed, and all of my test cases passed.

Tests cases:

Testing NVIDIA drivers install on non-GPU instance does nothing
Testing NVIDIA drivers install on GPU instance
Specifying different versions for NVIDIA drivers install

    - Make sure to install the linux-modules-nvidia package for the
      kernel flavour in use, when passing the --gpgpu argument, so
      that we can deliver a working NVIDIA installation, provided
      that the EULA was accepted.

  [ Jean-Baptiste Lallement ]
  * ubuntu-drivers,
    UbuntuDrivers/detect.py,
    tests/ubuntu_drivers.py:
    - Add a --free-only parameter, so as to allow installing only the
     available free drivers. This is a backport of only the
     ubuntu-drivers-common specific part of LP: #1819207, since
     it is tied to the rest of the changes to the test suite.
    - Add support for testing against a fake archive with free and
      non-free components.
    - Add static code checker.
  * debian/control:
    - Add pycodestyle and pyflake8 to build depends.
