====== Linux: Fedora- Client ====== here are some basics for setting up Fedora. Actual Version: 43 Useful Docs also: [[https://github.com/devangshekhawat/Fedora-43-Post-Install-Guide|https://github.com/devangshekhawat/Fedora-43-Post-Install-Guide]] ===== Graphics ===== ==== Basic codecs ==== Out of the Box there are not all multimedia codecs installed which are needed to decode propietary formats. 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 ==== Interfaces ==== There are different Hardware/Software Interfaces that are important for Video acceleration in 2D and 3D. From [[https://wiki.archlinux.org/title/Hardware_video_acceleration|https://wiki.archlinux.org/title/Hardware_video_acceleration]] : [[https://en.wikipedia.org/wiki/Graphics_processing_unit#GPU_accelerated_video_decoding_and_encoding|Hardware video acceleration]] makes it possible for the video card to decode/encode video, thus offloading the CPU and saving power. There are several ways to achieve this on Linux: * [[https://en.wikipedia.org/wiki/Video_Acceleration_API|Video Acceleration API]] (VA-API) is a specification and open source library to provide both hardware accelerated video encoding and decoding, developed by Intel. * [[https://en.wikipedia.org/wiki/VDPAU|Video Decode and Presentation API for Unix]] (VDPAU) is an open source library and API to offload portions of the video decoding process and video post-processing to the GPU video-hardware, developed by NVIDIA. * [[https://gpuopen.com/advanced-media-framework/|Advanced Media Framework SDK]] (AMF) is an open source framework which allows "Optimal" access to AMD GPUs for multimedia processing, developed by AMD. * [[https://en.wikipedia.org/wiki/Nvidia_NVDEC|NVDEC]]/[[https://en.wikipedia.org/wiki/Nvidia_NVENC|NVENC]] - NVIDIA's proprietary APIs for hardware video acceleration, used by NVIDIA GPUs from Fermi onwards. * [[https://www.khronos.org/blog/an-introduction-to-vulkan-video|Vulkan Video]] is an extension of the [[https://wiki.archlinux.org/title/Vulkan|Vulkan]] graphics API designed to support hardware-accelerated video encoding and decoding. For comprehensive overview of driver and application support see [[https://wiki.archlinux.org/title/Hardware_video_acceleration#Comparison_tables|#Comparison tables]]. === VA-API === This is the most used Interface for video acceleration and decoding itself. The example here is a very old card still supported by AMDGPU: root@pc-000700080009:~# vainfo Trying display: wayland Trying display: x11 libva info: VA-API version 1.22.0 libva info: User environment variable requested driver 'radeonsi' libva info: Trying to open /usr/lib64/dri-nonfree/radeonsi_drv_video.so libva info: Trying to open /usr/lib64/dri-freeworld/radeonsi_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva info: va_openDriver() returns 0 vainfo: VA-API version: 1.22 (libva 2.22.0) vainfo: Driver version: Mesa Gallium driver 25.3.6 for AMD CAICOS (DRM 2.51.0 / 6.19.11-200.fc43.x86_64, LLVM 21.1.8) vainfo: Supported profile and entrypoints VAProfileMPEG2Simple : VAEntrypointVLD VAProfileMPEG2Main : VAEntrypointVLD VAProfileVC1Simple : VAEntrypointVLD VAProfileVC1Main : VAEntrypointVLD VAProfileVC1Advanced : VAEntrypointVLD VAProfileH264ConstrainedBaseline: VAEntrypointVLD VAProfileH264Main : VAEntrypointVLD VAProfileH264High : VAEntrypointVLD VAProfileH264High10 : VAEntrypointVLD VAProfileNone : VAEntrypointVideoProc Please check to use the right driver (see beneath), and not maybe r600, which would be the first matching driver, if the environment LIBVA_DRIVER_NAME had not been set. === VDPAU === Basically a good way, to put load from the cpu to gpu. But: The Mesa-Project, which is the base-project for all desktops and many programs that did support the interface, now does not any more, which is why that interface from Mesa will die: https://forums.gentoo.org/viewtopic.php?t=1177112 Post by grknight » Wed Mar 18, 2026 12:48 pm Oh, so mesa removed VDPAU support with version 25.3.0 Now anything that depended on it should be removed. Please disable all vdpau on your system. Edit: Try vaapi instead system-wide. Mesa should provide a vaapi driver for radeonsi To still be able to unload rendering to GPU, you ma y use the LIBVDPAU-VA-GL ( [[https://github.com/i-rinat/libvdpau-va-gl|https://github.com/i-rinat/libvdpau-va-gl]] ). This Library will offer VDPAU by using VA-API and OpenGL. See beaneath for setup. === Vulkan === This is the actual framework for using 3d graphics in Linux. It will be the best supported Interface in the Future. To tes, use: vulkaninfo | grep VK_KHR_video_ ==== For AMD ==== 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 dnf install libvdpau-va-gl By default, most Linux deliver radeon- driver, which is open source and stable, but lacks important features. For AMD, one should switch to AMDGPU if possible (supported card by that driver). To do so: root@pc-000700080009:~# sudo nano /etc/default/grub Add to GRUB_CMDLINE_LINUX the following Parameters: radeon.si_support=0 amdgpu.si_support=1 radeon.cik_support=0 amdgpu.cik_support=1 and update Grub: root@pc-000700080009:~# sudo grub2-mkconfig -o /boot/grub2/grub.cfg Blacklist radeon - this is needed for Vulkan ro work properly: root@pc-000700080009:~# echo "blacklist radeon"> /etc/modprobe.d/blacklist-radeon.conf Reboot. lsmod should than not show radeon any more. Environment: to make the Interfaces using the Driver root@pc-000700080009:~# nano /etc/environment and put the lines in it: LIBVA_DRIVER_NAME=radeonsi # 10.04.2026 No support from mesa for VDPAU any more, use libvdpau-va-gl VDPAU_DRIVER=va_gl Hint: Also the driver is changed to **AMDGPU**, you need to set **radeonsi** as value for LIBVA there! VDPAU will work via VA-API: root@pc-000700080009:~# export VDPAU_DRIVER=va_gl root@pc-000700080009:~# vdpauinfo display: :0 screen: 0 libva info: VA-API version 1.22.0 libva info: User environment variable requested driver 'radeonsi' libva info: Trying to open /usr/lib64/dri-nonfree/radeonsi_drv_video.so libva info: Trying to open /usr/lib64/dri-freeworld/radeonsi_drv_video.so libva info: Found init function __vaDriverInit_1_22 libva info: va_openDriver() returns 0 API version: 1 Information string: OpenGL/VAAPI backend for VDPAU Do not install / use * **libva-vdpau-driver** **This would be the other way round (use VA-API via VDPAU Driver!)** ==== Intel ==== 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 intel-media-driver --allowerasing Environment: to make the Interfaces using the Driver root@pc-000700080009:~# nano /etc/environment and put the lines in it: LIBVA_DRIVER_NAME=intel VDPAU_DRIVER=intel ==== NVIDIA ==== to say it like a wise man did: fuck you nvidia ==== Fragmentation/Snapshotting ==== If you like BTRF because of its powerful Features and Snapshots, you need to set up BTRFs Assistant. ===== Annoying Plasmoids ===== like weather and such: sudo dnf remove kdeplasma-addons ===== Akonadi ===== i don't like those tools.
