here are some basics for setting up Fedora. Actual Version: 43

Useful Docs also: https://github.com/devangshekhawat/Fedora-43-Post-Install-Guide

Out of the Box there are not all multimedia codecs installed.

To use h264 and vlc, you need to:

sudo dnf config-manager setopt fedora-cisco-openh264.enabled=1
sudo dnf install vlc
sudo dnf install python-vlc

dnf install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
dnf install libavcodec-freeworld --allowerasing
dnf install https://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
dnf install mesa-va-drivers-freeworld --allowerasing

Wichtig: Der default Radeon-Treiber sollte ersetzt werden durch den AMDGPU- treiber, siehe hier: AMDGPU

oder so:

root@pc-000700080009:~# sudo nano /etc/default/grub

An die Kernelzeile (GRUB_CMDLINE_LINUX) in die Parameter anhängen:

radeon.si_support=0 amdgpu.si_support=1 radeon.cik_support=0 amdgpu.cik_support=1

Dann Update von Grub:

root@pc-000700080009:~# sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Konfiguration der Umgebungsvariabeln:

Dieser Treiber unterstützt VA-API von Haus aus:
Wichtig ist, dass keine (!) Kompatibilitäts- Layer zwischen VDPAU ind VA-API installiert werden. Es darf daher nur libvdpau installiert sein:

root@pc-000700080009:/etc# dnf list --installed | grep vdpau
libvdpau.x86_64                                      1.5-10.fc43

Keine:

libva-vdpau-driver

libvdpau-va-gl

to say it like a wise man did: fuck you nvidia

If you like BTRF because of its powerful Features and Snapshots, you need to set up BTRFs Assistant.

like weather and such:

sudo dnf remove kdeplasma-addons

i don't like those tools. Make your machine slow by scanning files and such… so remove it:

sudo dnf remove akonadi-server
