"ubuntu-drivers install" needs to be used when installing nvidia-driver if enabling "third-party packages"

This bug was fixed in the package ubuntu-drivers-common - 1:0.9.2.2

---------------
ubuntu-drivers-common (1:0.9.2.2) impish; urgency=medium

  * ubuntu-drivers:
    - Enable KMS Wayland if nvidia >= 470. This only affects
      the UDA drivers. This is more effective than checking
      if Wayland is running, since the live image uses X11.
  * UbuntuDrivers/detect.py:
    - Add newline when setting kms.
  * ubiquity/target-config/31ubuntu_driver_packages:
    - Install nvidia-prime, so that we can handle hybrid
      systems, and pick up the NVIDIA driver configuration
      (LP: #1943816).

The ubiquity doesn't call `ubunut-drivers install` to install (at least) nvidia drivers but workaround by copying configurations[1].

It's because calling the "ubuntu-drivers install" might be an unexpected call flow (calls "ubuntu-drivers install" in chroot stage of ubiquity) and the solution may need to change a lot[2]. To implement it will be better in coming release and workaround (by copying configurations) in previous releases.

However, to use "ubuntu-drivers install" is the correct/final way to make sure the logic of selecting/configuring the configurations for proprietary drivers.

I'll suggest to have "jjj/impish/hirsute/focal" series here to make sure we have solution(workaround) for each series (workaround in I/H/F and have the final solution in "jjj(22.04)").

@Alberto

Could we apply the modification in focal and hirsute?

I don't think applying the change to hirsute would actually be useful given that we won't be respinning ISOs for hirsute and users would need to update the ubuntu-drivers-common package from the Live system to get the fix.

debdiff for focal

The test case in this bug description seems to be about enabling RTD3 on laptops only and not about installing nvidia-prime and calling 'prime-select on-demand'. Please update the bug description so that it will pass review by the SRU team.

Previous discussion was at https://chat.canonical.com/canonical/pl/1mgrhibwpj8ojxk89tbpztjdar. Due to the design of ubiquity, it only use ubuntu-driver to get package list and install package in 31ubuntu_driver_packages. But ubuntu-driver not only install packages but also create configurations of Nvidia GPU. This patch will copy configurations and calling prime-select to make sure it get same result as calling "ubuntu-driver install" directly.

Hello jeremyszu, or anyone else affected,

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.

Tested with iso built from live-build and import ubuntu-drivers-common from focal-proposed. After installation finished, check /var/log/installer/syslog can see error log as attachment. It says "ubiquity: chroot: failed to run command ‘prime-select’: No such file or directory", because 31ubuntu_driver_packages is called by target config hook which is run before target install stage. Also tested with 21.10 iso file and will got same error message in log.

Create iso with live-build and import ubuntu-drivers-common 0.9.0~0.20.04.4 from focal-proposed. Install Ubuntu with "third-party packages" enabled. After installation finished, '/run/nvidia_runtimepm_supported' had been created and use 'prime-select query' get 'on-demand'
