** Description changed: + [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] + + * ubuntu-drivers debug + ``` + ... + === matching driver packages === + nvidia-driver-510: installed: <none> available: 510.54-0ubuntu2 [distro] non-free modalias: pci:v000010DEd000025A0sv00001028sd00000A61bc03sc02i00 path: /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 vendor: NVIDIA Corporation model: GA107M [GeForce RTX 3050 Ti Mobile] + ... + nvidia-driver-470: installed: <none> available: 470.103.01-0ubuntu2 (auto-install) [distro] non-free modalias: pci:v000010DEd000025A0sv00001028sd00000A61bc03sc02i00 path: /sys/devices/pci0000:00/0000:00:01.0/0000:01:00.0 vendor: NVIDIA Corporation model: GA107M [GeForce RTX 3050 Ti Mobile] support level: LTSB + ... + ``` + * As you can see, "(auto-install)" is point to 470 because of 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.
