System-upgrade and kmod(-nvidia) issue

With dnf system-upgrade with installed kmod (so far often reproduced with nvidia), the upgraded system doesn't show the available kernel module (with modinfo nvidia) despite the kmod package been present for the updated kernel. The issue isn't reproducible so far with dnf update --releasever=36 and only saw with dnf system-upgrade.

This can easily be fixed by using "sudo depmod -ae" and rebooting the system.

NVIDIA driver and simpledrm conflicts

Since the fedora 36 feature related to simpledrm , there were an early conflict with simpledrm and the nvidia driver early initialisation routine. Since the fedora kernel is now preventing to enable simpledrm if nvidia is detected, the patches provided in our RPM Fusion package have been dropped with the newer packages.

FFmpeg-free conflicts

With a single maintainer introducing a ffmpeg-free binary packages into Fedora, competing with our fully featured ffmpeg build, this leads to various conflicts and interactions issues. While one could admittedly rejoice from the ffmpeg introduction intro Fedora (enabling ffmpeg support for some fedora package lacking it), the method used to forcibly introduced an un-backed (by most RPM Fusion packager involved) package with uncertain features enabled, was perceived as unfriendly for the least. A determining argument for any "new eyes" is the very short time the Fedora review took compared with a fully backed 6 months Fedora feature review process.

Having non-competing packages in fedora+rpmfusion repositories is not a side thing, this is the reason why the RPM Fusion projects was created in the first place. Because of that we cannot afford support for ffmpeg-free at all and will recommend to migrate to our fully featured version.

TBD

VLC dropped support for VA-API hw acceleration

The VLC video player is built with system "ffmpeg" package which was updated to 5.0x branch in fc36. This update have seen a big change in how the "ffmpeg" library handle VA-API support and this has leaded to big changes in the vlc 4.x code base. While some changes have been made into the vlc 3.x branch to support ffmpeg-5 this isn't the case so far for the VA-API changes.

Long term fix will be to move to vlc-4.x (no estimated release date yet). or backport the fix for VA-API and ffmpeg5 (someone needs to do the port). or switch to VDPAU (using the libvdpau-va-gl package might only work under Xorg).

NVIDIA driver / Kepler GPU

The NVIDIA driver from the 495 series has dropped support for some older cards (Kepler generation), users upgrading from earlier Fedora are advised to verify which driver best fit their needs (and remember nouveau exists). The new 470xx legacy series has been introduced in older Fedora. Users will migrate by default to this series. See also Howto/NVIDIA

CUDA 11.5 / GLIBC 2.34

The CUDA compiler have some interaction issue with the newer glibc in Fedora and others distributions. This will be addressed by NVIDIA CUDA team within a forthcoming CUDA 11.5 minor release.

vlc

From time to time, VideoLAN vlc upstream team issue an update where the version miss-matches between the RPM package and the "about dialog". This is an upstream issue that isn't fixed downstream. Please consider the package version as the only source of true, specially when reporting to upstream bug tracker. (ex: rpm -q vlc vlc-3.0.12.1-1.fc34.x86_64 whereas the about dialog reports 3.0.11.1).

Fedora 32

Steam/gnome

With a default update of the package, gnome-shell might be triggered even on non Fedora Workstation Spin.

Kodi 18/python3

Fixed with kodi-18.6-4.fc32. The maintainer has reverted the change to python3 and built with python2. One can experience sides effects with configurations, so one might have to clear settings...

Original issue:

With python2 been deprecated in early 2020, it become unreliable to maintain a python2 on newer Fedora releases. Because of that, kodi will only be provided with python3 support on RPM Fusion for Fedora 32 and later (backporting patches when needed). If you rely on some non-packaged extension, please verify that python3 support is available for them and try to forward the question to the upstream maintainer of the extension.

This backported python3 support is ahead of the upstream target to support python3 by kodi v19 (not yet scheduled).

In the end, if you are affected any extension still not ported to python3. You may delay the update of Fedora to 32 or later for any Kodi usage. And wait for Kodi 19 before to update to a newer Fedora.

NVIDIA/340xx/kernel-5.6

Original issue:

The nvidia 340xx driver isn't yet compatible with the kernel provided by default for fedora. Please remind that 340xx driver will be provided on best effort basis as it's not supported anymore by NVIDIA.
