Ok, I have accepted all the packages into -proposed pockets besides
nvidia-prime for bionic. There seems to be an old unverified nvidia-
prime/u-d-c SRU in bionic-proposed that needs to be handled first. Can
someone take a look at LP: #1904583?
Another thing: since this is a whole backport of the prime-settings, I'd
like some more aging and manual exploratory testing of this before we
proceed.
Final thing, regarding the nvidia-prime part: looking at the diff I saw this
change bundled in it:
@@ -152,10 +154,10 @@
# (No need to check if nvidia is available)
self._enable_nvidia()
elif profile == "on-demand":
- self._disable_nvidia(keep_nvidia_modules=True)
if self._supports_runtimepm():
self._enable_runtimepm()
self._enable_kms()
+ self._disable_nvidia(keep_nvidia_modules=True)
else:
# Make sure that the installed packages support PRIME
#if not self._supports_prime():
I only noticed it after already accepting groovy. Just wanted to make
sure: is this related to the initramfs update? Was it needed? Is this
change expected?
Thank you.

Bug description:
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 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.
