** Description changed: [Steps to reproduce] 1. Install 20.04.3 with "Third-party packages" on a system which containing a RTD3 supported nvidia card. 2. After the installation, press enter to reboot system 3. prime-select query [Expected result] on-demand [Actual result] performance --- It's because ubiquity launches `ubuntu-drivers install --packages-list ...` in live system but install each package to target storage. When installing nvidia-prime, the preinst set "on" to "/etc/prime- discrete" which will be referred by gpu-manager. The gpu-manager will set to performance mode. After confirming with Alberto on Mattermost, since we don't have a nvidia driver which lower than 450 version since focal. I think we are ok to switch to on-demand mode. --- [Impact] - * Ubuntu will set GPU mode to performance as default which may use more power - * User can't use GPU for other purpose (eg: deep-learning) if RTD3 is not supported - * According to Nvidia README, the RTD3 doesn't support on non-laptop machine + * Ubuntu will set GPU mode to performance as default which may use more power + * User can't use GPU for other purpose (eg: deep-learning) if RTD3 is not supported + * According to Nvidia README, the RTD3 doesn't support on non-laptop machine [Test Plan] - * Install Ubuntu, and then execute 'ubuntu-drivers install' to install GPU driver. After the installation, reboot the system. Execute "prime-select query" should get "on-demand" - * On non-laptop machine. Can set GPU mode to on-demand - * On laptop with GPU in runtime PM support list. Set GPU mode to on-demand and Nvidia driver is loaded with "NVreg_DynamicPowerManagement=0x02" + * Install Ubuntu, and then execute 'ubuntu-drivers install' to install GPU driver. After the installation, reboot the system. Execute "prime-select query" should get "on-demand" + * Old GPU (which supported by nvidia-390 only) will keep in performance mode, refer LP:1957094. Execute "prime-select query" should get "nvidia" + * On non-laptop machine. Can set GPU mode to on-demand + * On laptop with GPU in runtime PM support list. Set GPU mode to on-demand and Nvidia driver is loaded with "NVreg_DynamicPowerManagement=0x02" [Where problems could occur] - * on-demand mode combined two features which are GPU offloading and RTD3. Nvidia driver lower then 450 (nvidia-driver-390) does not supported RTD3 and only have GPU offloading feature. - * With GPU supported RTD3 not able enable runtime PM on non-laptop. But based on the Nvidia README, this case shall not happened. + * With GPU supported RTD3 not able enable runtime PM on non-laptop. But + based on the Nvidia README, this case shall not happened.
