** Description changed: - The different power profiles require loading the nvidia drivers with - different options (or blacklisting them, in case of intel mode). + Since we introduced support for dynamic power management, on systems + with hybrid graphics (LP: #1904583), the need to load drivers with + different options has become more evident. - We need to call update-initramfs whenever we switch to a different - profile, or things may fall out sync, resulting in a failure. + We need to make sure that the files in the initramfs are in sync with + the current user selection. - The update-initramfs command takes a few seconds, therefore we also need - to provide feedback, so that users know that they have to wait for the - operation to complete. For this reason, prime-select will provide a - spinner on the command line, and nvidia-settings will show a progress - dialog. + 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.

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.
