---------------
ubuntu-drivers-common (1:0.9.2.4~0.21.10.2) impish; urgency=medium
* UbuntuDrivers/detect.py:
- Handle Production branches (PB) (LP: #1964747).
- Always prefer PB and LTSB, and pick the highest of the two
whenever possible.
* tests/test_ubuntu_drivers.py:
- Add test_system_driver_packages_chroot_support_branch_pb and
test_system_driver_packages_chroot_support_branch_pb_1, to
keep track of our policy on PB and LTSB releases.

Bug description:
[Impact]
* In Ubuntu 22.04, ubuntu-drivers install will install nvidia-470 instead of
510. (the ubuntu-drivers install is the best and recommended way to install
nvidia driver).
* nvidia-470 is LTSB (although webpage shows PB) and nvidia-510 is PB, in
this case, we need to chose the newer version since the support is fair in both
version.
* Also, 22.04 announces Wayland supports but nvidia-470 doesn't support in
Wayland scope at least from gdm upstream.
[Test Plan]
* Call "ubuntu-drivers debug" and check that 510 is marked as
"(auto-install)"
```
...
=== matching driver packages ===
nvidia-driver-510: installed: <none> available: 510.54-0ubuntu2 [distro]

model: GA107M [GeForce RTX 3050 Ti Mobile] support level: LTSB
...
```
* As you can see, "(auto-install)" points to 470 because it owns LTSB tag.
[Fix]
* Adjust the priority in UbuntuDrivers/detect.py, if the PB and LTSB
versions found, then it needs to pick the newer version one.
[Where problems could occur]
* It has less possible to introduce regression since the patch only changes
_cmp_gfx_alternatives() which counts the priority of nvidia drivers be
installed.
* In Ubuntu, we have nvidia-390, 470 and 510 so far as I known and these
cases are listed in test_system_driver_packages_chroot_support_branch_pb.

+ nvidia-graphics-drivers-510 (510.54-0ubuntu0.20.04.1)
+
+ * New upstream release (LP: #1961075):
+ - Fixed a bug that could cause GPU exceptions when minimizing a
+ fullscreen Vulkan application on certain desktops, such as
+ Plasma.
+ * debian/templates/control.in:
+ - Set XB-Support to PB (production branch).
+ * debian/rules.defs:
+ - Add support for video ABI 25.
---
Since
* debian/templates/control.in:
- Set XB-Support to PB (production branch).
The u-d-c will choose LTS branch instead of PB branch.
because `def _cmp_gfx_alternatives(x, y):` doesn't define PB.
