** Description changed: ubiquity calls ``` ubuntu-drivers install $FREEONLY $NOOEM --package-list /run/ubuntu-drivers.autoinstall ``` to generate package list during live system but "ubuntu-drivers install" not only install packages but also create some config files for switching nvidia mode (e.g. on-demand) and change the runtime config as well (e.g. modify the iniramfs). Thus, not only package list needs to be referred but also the configuration. --- In ubuntu-drivers-common, which read the "/run/ubuntu-drivers.autoinstall" to install package. It also skipping the nvidia-mode changing (made by ubuntu-drivers install). ``` $ cat ubiquity/target-config/31ubuntu_driver_packages #!/bin/sh set -e # install all packages that "ubuntu-drivers autoinstall" installed into the # live system. Ubiquity calls this with --package-list /run/ubuntu-drivers.autoinstall PKGLIST=/run/ubuntu-drivers.autoinstall [ -e $PKGLIST ] || exit 0 for p in `cat $PKGLIST`; do apt-install $p done ``` --- We need to use a same approach to make sure the nvidia mode is same on a same system (either all handing by ubuntu-drivers install or change the logic to maintainer script in each package). --- [Impact] * According to Nvidia README, the RTD3 (Runtime D3) doesn't support on non-laptop machine - * Patch make system not enable RTD3 unless it's a laptop * Install Ubuntu with "third-party packages" enabled, will not get same GPU configuration by running "ubuntu-drivers install" + * Patch make system not enable RTD3 unless it's a laptop and set default GPU mode to "on-demand" [Test Plan] - * Install Ubuntu on machine with "third-party packages" enabled + * Create Focal iso with live-build and import ubuntu-drivers-common from -proposed + * Install Ubuntu on machine, in "Updates and other software" page select "Install third-party software for graphics and Wi-Fi hardware and additional media formats" * On laptop with Nvidia RTD3 supported GPU. The configuration file '/run/nvidia_runtimepm_supported' will be created. - * Execute "prime-select query" should get "on-demand" + * Call "prime-select query" to make sure the default mode is "on-demand" [Where problems could occur] * With non-laptop machine use RTD3 supported GPU may use more power [Other Info] - * For RTD3 (Runtime D3) doesn't support on non-laptop machine, refer to + * For RTD3 (Runtime D3) doesn't support on non-laptop machine, refer to https://bugs.launchpad.net/oem-priority/+bug/1942788
