We need to make sure that the files in the initramfs are in sync with the current user selection. This is also a chance to update the old nvidia-settings release in the archive. [Impact] * If the modules list is not in sync with the selected power profile, users may experience a black screen or increased power consumption. * Updating the initramfs can take a few seconds, and we need to provide users with some form of visual feedback. [Fix] * The prime-select tool shoud update the initramfs when switching between power profiles, and provide visual feedback. * The nvidia-settings panel should provide a progress dialog, since profile switching would otherwise freeze the UI until update-initramfs completes. [Test Case] Make sure a supported nvidia driver is installed (450, 460), then install nvidia-prime and nvidia-settings from proposed, and check the following: 1) prime-select query (to check your current profile) 2) sudo prime-select on-demand (or "intel", or "nvidia", depending on your current power profile) 3) Check that the operation completes successfully. 4) Reboot your system 5) Launch the nvidia-setting panel. 6) Select a different profile from the PRIME tab, and check that a progress dialog is correctly displayed. 7) Close the nvidia-settings panel, and reboot. [Regression Risk] Medium, while the changes in prime-select are trivial, nvidia-settings needs careful testing.
