Bug description:
As we introduced the "-server" NVIDIA drivers, and the concept of
"LTSB" (Long Term Support Branch) and "NFB" (New Feature Branch)
releases, the detection logic behind ubuntu-drivers needs an update to
make the correct choices for the user.
The introduction of the NVIDIA 450 series, also added runtime power
management, which greatly improves user experience on systems with
hybrid graphics, and allows greater power savings. When supported, on-
demand mode and runtime power management are the default. Both gpu-
manager and ubuntu-drivers in ubuntu drivers common, and the tools in
the nvidia-prime package need updating as a result.
Only the components in Ubuntu 20.10 require a fairly small diff for the
backport. The rest is a direct sync of the 1:0.8.6.3 release in 21.04.
== Ubuntu 20.10 ==
ubuntu-drivers-common (1:0.8.6.3~0.20.10.1) groovy; urgency=medium
* UbuntuDrivers/detect.py,
tests/test_ubuntu_drivers.py:
- Prefer LTSB releases over NFB ones for non gpgpu cases too.
* gpu-manager.c:
- Make it possible to force runtimepm by creating the
/etc/u-d-c-nvidia-runtimepm-override file.
- Make on-demand default on nvidia >= 450, when no
previous settings are available.
nvidia-prime (0.8.15.1~0.20.10.1) groovy; urgency=medium
[ Anthony Fok ]
* Remove obsolete udev rules during `postrm upgrade` too
== Ubuntu 20.04 ==
ubuntu-drivers-common (1:0.8.6.3~0.20.04.1) focal; urgency=medium
* Backport 1:0.8.6.3 (LP: #1904583).
nvidia-prime (0.8.15.1~0.20.04.1) focal; urgency=medium
[ Alberto Milone ]
* prime-select:
- Enable runtimepm in on-demand mode if supported (LP: #1895855).
- Disable workaround for on-demand mode.
- Enable KMS if runtimepm is supported.

[ Kai-Heng Feng ]
* prime-select: Remove udev rules
== Ubuntu 18.04 ==
ubuntu-drivers-common (1:0.8.6.3~0.18.04.2) bionic; urgency=medium
* Backport 1:0.8.6.3 (LP: #1904583).
* gpu-manager.c: add missing PCI_CAP_ID_NULL definition
nvidia-prime (0.8.15.1~0.18.04.1) bionic; urgency=medium
* Backport 0.8.15.1 (LP: #1904583).
