** Description changed: [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 [Test Plan] - * Install 20.04.3 with "Third-party packages". After the installation, reboot the system. Execute "prime-select query" should get "on-demand" + * 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" [Where problems could occur] * on-demand mode supported after nvidia driver 450. And focal does not have nvidia driver lower than 450. * With GPU supported RTD3 not able enable runtime PM on non-laptop. But based on the Nvidia README, this case shall not happened.
