You could choose a small scope project and drive it to perfection. You could probably make a lot of money, live large, get a big house and five cars. Instead of that yours truly spent his time on his favorite Linux Mobile distribution. This talk gives a look back from how it all started until now, the technical changes postmarketOS went through, how our community got bigger and better and how the mainstream operating systems got worse over time. I'll already spoil the conclusion here, what we have been building together is more meaningful than ever in 2026, I'm proud of what we have accomplished and I'm so happy I didn't do something else instead! postmarketos-conference-2026-7-10-years-of-postmarketos Presentation track Oliver Smith en false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/X9CBBJ/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/X9CBBJ/feedback/ 5053.1 (Großer B-IT Raum) Talk 2026-09-25T10:35:00+02:00 10:35 00:20 As a self-hosted enthusiast and a person who cares about green tech, I have recently started a journey to self host more and more of the services I use frequently. At the last Open Source Summit Japan, I discovered PostmarketOS, a real Linux distribution for phones, which made me start experimenting with the possibilities reused hardware could bring to a more sustainable future. In this talk, I strive to describe the process and approach I had to setup a reliable, resilient Kubernetes cluster using only old phones with PostmarketOS and k3s, as well as giving tips to find more sustainable uses for said technologies. postmarketos-conference-2026-13-running-a-kubernetes-cluster-on-old-phones-with-postmarketos Presentation track dariogmori en The idea is to have a talk discussing how I set up the cluster and some tips and tricks to manage said clusters without them getting out of control.

One good example is the Mobile Linux distribution postmarketOS, where pre-release testing is conducted manually by device maintainers and the project's community. Promising efforts to automate the process have seen work and remarkable progress for years, yet, it is unlikely that they will effectively close all gaps, obsoleting the need for manual testing. A key challenge for manual testing is the management of the process. Testers need proper guidance by well-designed test plans while developers and release managers need meaningful testing reports. While several tools exist for this purpose, most are too complicated and too heavy-weight for community projects. With KiwiTCMS and SystemTestPortal two open source systems are available that were designed to fill this gap. However, like any server-based system, employing these systems requires infrastructure setup and maintenance. This talk presents the conceptual idea of "SystemTestPortal Lite", an alternative to SystemTestPortal that runs completely in the web browser without the need to install or operate services. Instead, projects only need to provide data files with the test plans in their repositories. Test reports can be uploaded as files to issue trackers or the repositories so they can be aggregated before release decisions are made. postmarketos-conference-2026-16-manual-testing-in-2026-yes-seriously Presentation track Daniel Kulesz en false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/AJD9LX/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/AJD9LX/feedback/ 5053.1 (Großer B-IT Raum) Longer Talk 2026-09-25T14:40:00+02:00 14:40 00:20 This talk covers the reasoning behind automated Hardware in the Loop (HiL) testing of standard pmos devices.

That's what we're doing with nightly packages, where we build the development states of GNOME, KDE, Phosh, systemd and more, (hopefully) every night. postmarketos-conference-2026-12-shortening-the-development-feedback-cycle-nightly-repositories Presentation track Achill Gilgenast en Usually the feedback cycle for Alpine and postmarketOS has been that upstream developers of all projects do final releases, which we then start shipping. That means we can only report bugs and issues _after_ the final release is done. But if we build and test upstream projects as development happens, we can give feedback earlier and collectively ensure the final release has fewer regressions. That's basically the goal of our nightly repositories in postmarketOS. This talk covers how we're doing it and how you can help find bugs earlier.

However, what brings people together is rarely just technical, and very often strongly related to our emotions and ways of seeing the world. Unfortunately, we get a lot less training on communication and emotions than we get on writing kernel drivers or learning Rust. The goal of this worshop is to take a bit of time to try to collectively work in those tasks. postmarketos-conference-2026-6-listening-and-appreciation-workshop Hands-on track Pablo Correa Gomez en We will practice to 2 kind of exercises: - Listening experience: in small groups, one person will try to explain the situation where a conflict is happening. Another person will be taking notes to try to identify "facts spoken out", and a third one just listening. After the situation and the feelings have been explained, the person listening will try to reproduce what the first person said. The goal is to show to each other how our own listening and biases interfere with communication. We will rotate with the goal of everybody having a try at each of the different positions. - Appreciation work: in order to reduce conflicts and create a welcoming environment, appreciation of our own work, and the work of others is critical. In this exercise we will work on expressing that appreciation. By working individually, we will try to identify what we do, that benefits collectively the projects we work. We will then create small groups and do the same with appreciating others' work.

But Alpine has grown _a lot_ since then: we have many new architectures (one of which, riscv64, is unbelievably slow...), and a single failing test in one package still blocks the upload of all other, unrelated packages. TL;DR: the builders are very often the bottleneck of Alpine development.

I got a weird idea _(of course inspired by HP Palm/LG webOS and Firefox/KaiOS)_: what if my window manager was actually a webview kiosk? What if I could draw native apps pixel inside `<canvas>`? and then the whole interface could be written as you would code a web app _(and the shocking reality is that there are more web developers on earth than desktop manager ones)_? and that could actually load within a second, and render at 60 fps while consuming only a few megabytes of RAM? I enjoyed experimenting with that a lot because it actually helped me draw ergonomic interfaces for devices like feature phones _(I own a Nokia 8110 4G)_ that had none maintained for PostmarketOS _(RIP Bananui)_, and iterate really quickly with live reloading and all the great developer tooling that web browsers offer us. postmarketos-conference-2026-28-mure-a-malleable-window-manager Presentation track Yvan Sraka en This talk is meant to be accessible to everyone, but _trigger warning_: **some JavaScript is likely to be displayed on screen!** false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/8XRPTX/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/8XRPTX/feedback/ 5053.1 (Großer B-IT Raum) Talk 2026-09-26T11:40:00+02:00 11:40 00:20 [River](https://isaacfreund.com/software/river/) is a non-monolithic Wayland compositor that provides a stable window management protocol rather than hard coding window management logic in the compositor process.

There will be an overview of how the core protocol works followed by a discussion of the features especially important for mobile interfaces such as touch gesture support and on screen keyboards. Finally, we will examine the current limitations and how they can be resolved in the future.

It was not designed for containers, cloud computing or smartphones, yet it eventually found its way into all three. In this talk, Alpine’s founder looks back at five lessons from more than twenty years of building and maintaining the project: how real constraints can produce unexpected opportunities, why simplicity must include the contributor experience, how being different can pay off, why neglected work eventually becomes technical debt, and why a friendly community is part of a project’s technical quality and security. This is not a complete history or a celebration of everything Alpine got right. It is a candid account of decisions that worked, mistakes that became apparent years later, and what it takes for an open-source project to survive beyond its original purpose. postmarketos-conference-2026-22-five-lessons-from-building-alpine-linux-for-20-years Presentation track Natanael Copa en false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/WKQDXE/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/WKQDXE/feedback/ 5053.1 (Großer B-IT Raum) Longer Talk 2026-09-26T14:40:00+02:00 14:40 01:00 The postmarketOS governance has evolved through the years.

An initial team was assembled, roles where created, and people that put a lot of work organically joined the team. But that contribution model has problems to scale. In 2023 the model was changed to allow people to ask to join, leading in to a considerable growth: from 8 maintainers back then to 29 nowadays. The growth, however, has resulted in greater organizational challenges, and the initial maintainers still kept greater power than everybody else. In order to change this, a legal entity has been created, with democratic governance at heart.

Notably, I'll recount: - following the development process of audio on the Fairphone 5, from a user's point of view - traveling with pmOS - notes UI-hopping between GNOME, Phosh, and KDE - various fun tidbits (and scares) throughout I'll then finish by going over a couple small projects/fixes I dabbled in, showing how you can easily contribute anywhere in the ecosystem where you see an improvement. And, of course, most importantly... will I go back to Android?

As such, operating systems like Android have undertaken serious efforts to harden themselves against attackers. At the heart of Android's hardening efforts is SELinux, an implementation of mandatory access control (MAC). In this presentation, we will explain what MAC is and showcase the benefits of SELinux. We will briefly compare it to AppArmor and then look into the history of MAC in postmarketOS and the technical challenges that come with integrating SELinux into Alpine Linux and postmarketOS. Thanks to the work done by members of the postmarketOS SELinux effort, we will even showcase a demo at the end! false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/8RZSQ9/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/8RZSQ9/feedback/ 5053.1 (Großer B-IT Raum) Talk 2026-09-27T14:40:00+02:00 14:40 00:20 There is initial support for a few Virtual Reality devices in postmarketOS, including Oculus Go, Lynx R1, META Quest 3S (panther) and the upcoming Steam Frame. I also own a OnePlus 6 which runs Godot Native Mobile VR with a Cardboard-compatible smartphone holder. Combining this with a Vive Tracker and libsurvive gives you six degrees of freedom in Godot Beep Saber VR. postmarketos-conference-2026-17-virtual-reality-on-postmarketos Presentation track HaeckseAlexandra en I am a long time PC Virtual Reality user (Valve Index) and avoid the Meta Quest and other Android devices. When the Steam Frame was announced, I asked my self will it run postmarketOS or another distro? I had a look a https://wiki.postmarketos.org/wiki/Category:Headset and found out that none of the devices fits my use case. So I started building my own one, based on HadesVR. Since I know that my OnePlus 6 is alreay supported by both Godot Native Mobile VR and postmarketOS, I think that is a good startingpoint. My next plan is to get Godot Engine running on a postmarketOS phone, once that works start porting Monado. For 6DoF Tracking, I will be using libsurvive (an Open Source Lighthouse Tracking library) with a Vive Tracker. My future plans include testing VR on more postmarketOS devices, as well as porting games including Overte and the Luanti OpenXR branch. I will also build my own libsurvive compatible trackers using an IMU, an RP2040 and TS4231 sensors. Wireless trackers will use the Nordic Semiconductor nRF52840, which is also used by Smol Slime Trackers and the Crazyradio 2.0. false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/8UMTPU/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/8UMTPU/feedback/ 5053.1 (Großer B-IT Raum) Talk 2026-09-27T15:10:00+02:00 15:10 00:20 Trying to solve the problems of working with imperative package definitions, one crate at a time. postmarketos-conference-2026-39-corroding-alpine-performant-apkbuild-capable-tooling Presentation track Patrycja Rosa (ptrcnull) en false https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/RJMFN8/ https://pretalx.postmarketos.org/postmarketos-conference-2026/talk/RJMFN8/feedback/ 5053.1 (Großer B-IT Raum) Talk 2026-09-27T16:00:00+02:00 16:00 00:20 [xiotrace](https://codeberg.org/neuschaefer/xiotrace) hooks the XNU kernel used on certain mobile devices in order to trace I/O operations such as SPI transfers.
