Synopsis

This howto illustrates how to configure Looking Glass on NixOS.

Prerequisites

NixOS 25.11 (unstable should work, but I haven't tested it)
Looking Glass B7
systemd 258 (because of this)

Navidrome setup

Decided to spend a Saturday evening setting up Navidrome on my homelab PC. The plan was to be able to listen to music that’s stored on my Synology NAS on my phone regardless of where I am, meaning I’d probably be looking at setting up Tailscale as well. Here's what I had to do:

Prerequisites

Acquire cheap AF hardware. In my case, a 2nd hand 30 eur mini-PC
Install Proxmox to it. I used this guide (also installed Home Assistant)

Setup steps

Install Navidrome using the Navidrome Proxmox VE Helper-Script
Enable NFS share on my Synology’s music library partition
A crucial step in making it possible for the navidrome user to be able to actually see the files within the NFS share was to select ”Squash: Map all users to admin” when setting up the NFS rule in Synology control panel. Unsure if ”Map all users to guest”

Migrate Proxmox ZFS Boot Pool (rpool) from NVMe to SATA SSDs

This guide documents how to migrate your Proxmox bootable ZFS mirror (rpool) from two NVMe drives to two SATA SSDs of the same size, preserving bootability via UEFI.

Summary

From:

ZFS mirror on: /dev/nvme0n1p3, /dev/nvme1n1p3
UEFI boot partitions: /dev/nvme0n1p2, /dev/nvme1n1p2

Note

Set the $URL variable with your URL for easy copy and paste

Example:

export URL='https://youtu.be/PLUZDtJCdDM'

Automount SMB under Bazzite

Make sure that you replace whatever is in "<>" with your own data.

Setup authentication configuration file

Generate a file that defines the login data to mount the volume. The file will be called credentials located at /var/home/<username>/.smb/credentials. Make sure you first generate the folder mkdir /var/home/<username>/.smb.

I asked 1 high-quality question in 2024, and it was closed almost immediately, and I haven't engaged with the site since.

If someone with 20,000+ karma has their nicely-formatted questions closed so quickly, what must the newbies and rank-in-file encounter? This is probably a big reason why it's declining.

QEMU with VirtIO GPU Vulkan Support

With its latest reales qemu added the Venus patches so that virtio-gpu now support venus encapsulation for vulkan. This is one more piece to the puzzle towards full Vulkan support.

An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for VirtIO-GPU with a local development environment. Following up on the outdated write up, this is how its done today.
