How to make a new rpm-ostree desktop variant in Fedora?

So you want to make a new rpm-ostree desktop variant in Fedora to join Silverblue, Kinoite and Sericea? Here are the steps that you should follow.

First, you should figure out what packages should be installed in your image. To do that, you can start from the base container image (https://quay.io/repository/fedora-ostree-desktops/base) and add packages from the comps group corresponding to your desktop in Fedora : https://pagure.io/fedora-comps

At this point, you should consider which apps are going to be shipped by default, included in the image, and which ones are going to be installed by default as Flatpaks.

Once you've got something working, reproduce that in https://pagure.io/workstation-ostree-config using the comps group and the filter and sync script. Look at other variants for example.

ProxMox - Enable IOMMU using systemd

Fedora IOT AArch64 Kernel 6.2 Boot Fix

As reported by Fedora CoreOS team, on the AArch64 / ARM64 architecture the new 6.2 kernels will not boot due to older bootloaders in Fedora IoT.

Update

There is now some guidance from the Fedora IoT team on this here. This is probably the better course of action to take than my method below.

Go to OpenWRT release page, select the latest release stable release, then targets -> x86 -> 64. Right-click generic-ext4-combined.img.gz (not the "efi"!) and copy the link.
On the Proxmox host, download the archive and unpack it:

wget *paste link here*
gunzip openwrt-*.img.gz

Resize the image to be the size you want your VM's disk to be (example with 8 GiB):

Jellyfin API Authorization

To start using the Jellyfin API, authorization is probably the first thing you'll need to do. Jellyfin's authorization options can be a bit confusing because there are a lot of deprecated options.

Generally there are three ways to authenticate: no authorization, user authorization with an access token or authorization with an API key. The first way is easy, just do nothing. But most often you'll need to use either the access token or API key.

Sending authorization values

There are multiple methods for transmitting authorization values, however, some are outdated and scheduled to be removed. It's recommend to use the Authorization header. If header auth isn't an option, the token may be sent through the ApiKey query parameter. Sending secure data in a query parameter is unsafe as the changes of it leaking (via logs, copy-paste actions or by other means) are high. Only use this method as a last resort.

Linux (Manjaro [Arch]) on a Thinkpad P14s [T14] Gen2 with Intel

These are my installation-tricks and notes for running Linux on a 2021 Thinkpad P14s Gen2 with 11th gen Intel Core i7-1185G7. It should also be suitable for the Thinkpad T14 Gen2 with Intel as they are technically the same model.

Additionally you may find more AMD specific tips on the gist I've forked. I decided to keep this gist forked as I have used some of the tips they shared and because they inspired me to create my note in the first place.

Sadly there is no entry in the arch-wiki for Intel specific model, but some of the info from AMD one were useful for me. Other useful sources are mentioned in the document in their respective chapters.

Not everything in this doc may be 100% correct as I'm writing this note after having my PC set up and I might have forgotten some of the stuff. I will update it I ever decide to reinstall the OS on my PC.

Running Windows 10/11 Guest with GPU Passthrough using laptop running Fedora

Abstract

This is a full guide for people who wanted to set up Windows 10/11 VM with QEMU/KVM hypervisor enhancements for a laptop that is configured with hybrid graphics card like Intel/AMD + NVIDIA. This process will take about 1 to 2 hours, depending on your system's performance and your patience =)

There is another comprehensive guide you can follow here (shoutout to asus-linux team who made supergfxctl which is a very important tool for this guide). It is more up-to-date than mine. I would probably incorporate those information into my guide, but you are welcome to use this one as a reference!

Before we proceed:

This guide is exclusively for Fedora users because this distro is quite different to set up than other distro such as Arch. I would say Arch is easier to setup than Fedora, but sometimes you like to use Fedora than Arc

	#!/usr/bin/env -S bash -e

	set -o xtrace

	function set_gnome_configuration {
	# Disable Gnome animations
	gsettings set org.gnome.desktop.interface enable-animations false

	# Dock settings
	gsettings set org.gnome.shell.extensions.dash-to-dock show-apps-at-top true
