Personal settings for Fedora Silverblue, with lovely help from:
rpm-ostree upgrade
flatpak repair
flatpak uninstall -y --unused
flatpak update -y --appstreamRPM Fusion provides software that the Fedora Project or Red Hat doesn't want to ship. See https://rpmfusion.org/RPM%20Fusion for details.
Add the repositories:
rpm-ostree install https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
rpm-ostree install https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
systemctl rebootYou can now install overlayed packages or packages inside a toolbox from RPM Fusion.
To upgrade on major releases, e.g. Fedora Silverblue 39 > 40:
rpm-ostree update --uninstall rpmfusion-free-release --uninstall rpmfusion-nonfree-release \
--install rpmfusion-free-release --install rpmfusion-nonfree-releaseIf you ever get in trouble on upgrading, you can reset the current ostree (create a backup first):
rpm-ostree status
rpm-ostree reset
systemctl rebootRedo the giving steps and reinstall your packages.
Increasing nofile limits may be needed for certain applications and games to work.
See https://access.redhat.com/solutions/1257953 for more details.
Append the following to /etc/security/limits.conf:
$ cat /etc/security/limits.conf
* hard nofile 65535
* soft nofile 8192Depending on the situation, this file may not be used. You also need to adjust the systemd configuration:
# mkdir -p /etc/systemd/system.conf.d/
# cat /etc/systemd/system.conf.d/10-filelimit.conf
[Manager]
LimitNOFILE=65535# mkdir -p /etc/systemd/user.conf.d/
# cat /etc/systemd/user.conf.d/10-filelimit.conf
[Manager]
LimitNOFILE=65535Reboot the system to apply the increased limits.
NOTE: Enable this only when needed outside Flatpaks, and make sure RPM Fusion is configured first!
See https://rpmfusion.org/Howto/OSTree when using Intel/NVIDIA, and if you require Broadcom/DVB firmwares.
Override the current mesa-va-drivers:
rpm-ostree override remove mesa-va-drivers --install mesa-va-drivers-freeworldrpm-ostree install libavcodec-freeworld libva-utilsAfter a reboot, you can check support hardware decoding profiles using vainfo:
Trying display: wayland
libva info: VA-API version 1.20.0
libva info: Trying to open /usr/lib64/dri/radeonsi_drv_video.so
libva info: Found init function __vaDriverInit_1_20

TIP: You can also use Gnome Software to install additional codecs.
rpm-ostee install rpm-ostree install gstreamer1-plugins-bad-free-extras gstreamer1-plugins-bad-freeworld gstreamer1-plugins-ugly gstreamer1-vaapiTo enable VA-API on the Brave Browser Flatpak package, create the ~/.var/app/com.brave.Browser/config/brave-flags.conf file, with the following content:
--ignore-gpu-blocklist
--enable-zero-copy
--enable-gpu-rasterization
--use-gl=angle
--use-angle=vulkan
--enable-accelerated-video-decode
--enable-features=VaapiVideoDecoder,VaapiIgnoreDriverChecks,VaapiVideoDecodeLinuxGL,VaapiVideoEncoder,Vulkan,DefaultANGLEVulkan,VulkanFromANGLE,OneTimePermission,OverlayScrollbarDepending on your hardware, you may need to enable/disable different flags. See https://chromium.googlesource.com/chromium/src/+/refs/heads/main/docs/gpu/vaapi.md#vaapi-on-linux for details.
If you are using encryption on a NVMe/SSD, you may want to improve performance by disabling the workqueue.
See https://wiki.archlinux.org/title/Dm-crypt/Specialties#Disable_workqueue_for_increased_solid_state_drive_(SSD)_performance for details.
If you are using Btrfs, you may want to enable https://github.com/kdave/btrfsmaintenance:
rpm-ostree install btrfsmaintenance
nano /etc/sysconfig/btrfsmaintenanceEnable the services:
sudo systemctl enable btrfs-balance.timer btrfs-defrag.timer btrfs-scrub.timer btrfs-trim.timer --nowIt is discourage to install (large) software on the ostree. Try to use Flatpaks and toolboxes (toolbox create and toolbox enter) as much as possible.
You can pull the latest toolbox, using:
podman pull fedora-toolbox:40To update the Toolbox:
toolbox enter
sudo dnf update && sudo dnf upgradeYou can create multiple toolboxes, and even manage them using Podman Desktop.
To replace the provided default Firefox package, with the Firefox Flathub version for example:
rpm-ostree override remove firefox firefox-langpacksNOTE: You can also hide the desktop entry itself.
If you use Podman, and need Docker compatibility:
rpm-ostree install podman-dockerIf possible, enable and use rootless containers: https://wiki.archlinux.org/title/Podman#Rootless_Podman
TIP: See https://itsfoss.com/flatpak-app-apply-theme/ instructions for Flatpak theming.
rpm-ostree install gnome-tweak-toolWhen using GTK-3 apps, see https://github.com/lassekongo83/adw-gtk3 for details.
flatpak install org.gtk.Gtk3theme.adw-gtk3 org.gtk.Gtk3theme.adw-gtk3-darkAfter a reboot, you can apply theme settings using Gnome Tweaks.
