The "Which should I use?" table on the clients page listed most client names as bold text, not links — only the Decky plugin and pf-webos were clickable — so the client references appeared broken. Link each client to its section (or dedicated page), and fix a stale Windows headless command. Repo-wide docs correctness/staleness pass against the code: - steam-deck: client-not-found -> flatpak-not-found (the real backend code) - install: host cert is punktfunk-host-windows_<ver>.cer, not ..._setup.cer - configuration: GPU_PRIORITY_CLASS default is auto; 10BIT/444 are default-on - how-it-works/index: GameStream/Moonlight is opt-in (--gamestream) - roadmap: clipboard sync is shipped, not planned - install-client: MSIX/cert artifacts are arch-suffixed (_x64/_arm64) - requirements: fix garbled 22H2/IddCx sentence - status: Linux encode also covers AMD/Intel (VAAPI/Vulkan Video) - automation: add the plugins.changed event - windows-host: note the optional bundled VB-CABLE virtual mic - sway: PUNKTFUNK_COMPOSITOR=hyprland is a wlroots-family alias - running-as-a-service: punktfunk-probe is a source-build-only dev tool Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

title: Requirements
|
|
description: What you need to run a punktfunk host — GPU, driver, desktop, and network.
|
|
---
|
|
|
|
## Supported setups
|
|
|
|
A punktfunk host runs primarily on a Linux machine with a dedicated GPU — NVIDIA (NVENC) is the
|
|
most-exercised path, and AMD/Intel GPUs work via VAAPI. A native [Windows host](/docs/windows-host)
|
|
is also available. Setup splits along two axes: you **install** the package per distro, then
|
|
**configure** the host — and learn its quirks — per desktop/compositor.
|
|
|
|
> New here? Read [Security & Safe Use](/docs/security) first — a streaming host is remote control of
|
|
> the machine, so keep it on a trusted LAN or VPN and require pairing.
|
|
|
|
**Distros — install the package:**
|
|
|
|
- [Ubuntu / Debian](/docs/ubuntu)
|
|
- [Fedora](/docs/fedora)
|
|
- [Arch](/docs/arch)
|
|
- [Bazzite](/docs/bazzite)
|
|
- [SteamOS](/docs/steamos-host)
|
|
|
|
**Desktops — configure and quirks:**
|
|
|
|
- [KDE Plasma (KWin)](/docs/kde)
|
|
- [GNOME (Mutter)](/docs/gnome)
|
|
- [Steam / gamescope](/docs/gamescope)
|
|
- [Hyprland](/docs/hyprland)
|
|
- [Sway / wlroots](/docs/sway)
|
|
|
|
Pick your distro to install, then your desktop to configure — the two are independent. The host
|
|
needs one of these compositor backends to create a virtual display.
|
|
|
|
> **Windows host:** punktfunk also runs as a native host on **Windows 11 22H2 or newer (x64)** — a
|
|
> signed installer that registers a service and bundles a virtual-display driver whose driver
|
|
> framework (IddCx 1.10) makes 22H2 the hard floor — Windows 10 is not supported. It encodes on NVIDIA
|
|
> (NVENC), AMD (AMF), or Intel (QSV), with a software fallback, and is newer than the Linux host; see
|
|
> [Windows Host](/docs/windows-host).
|
|
|
|
## GPU and driver
|
|
|
|
- **An NVIDIA GPU** with NVENC — effectively any GeForce RTX or workstation card. NVENC is what
|
|
encodes the video in hardware.
|
|
- **NVIDIA driver 535 or newer** (550+ recommended). The driver must include the **GL/EGL userspace**,
|
|
not just `nvidia-utils` — without it the compositor can't initialise the GPU and capture fails. Each
|
|
install guide installs the right package (e.g. `libnvidia-gl-<version>` on Ubuntu).
|
|
- **`nvidia-drm modeset=1`** must be enabled (Wayland on NVIDIA needs it). The install guides cover this.
|
|
- **AMD / Intel GPUs** encode via **VAAPI** instead (install `mesa-va-drivers` or
|
|
`intel-media-driver`; validated live on AMD RDNA3). The NVIDIA-specific notes above don't apply
|
|
there. On modern Intel (Gen12/Tiger Lake and newer, including Arc) the driver only offers the
|
|
**low-power (VDEnc)** encode entrypoint — the host detects this and falls back automatically
|
|
(`PUNKTFUNK_VAAPI_LOW_POWER=1|0` pins it) — and low-power encode needs the **HuC firmware**
|
|
loaded (the kernel default on those platforms; check `dmesg | grep -i huc` if encoding fails).
|
|
A GPU-less software H.264 encoder also exists (`PUNKTFUNK_ENCODER=software`), meant as a
|
|
fallback rather than a daily driver.
|
|
|
|
> Consumer GeForce cards historically cap the number of **concurrent** NVENC sessions (a few at once);
|
|
> workstation cards don't. This only matters if you stream to many devices simultaneously.
|
|
|
|
## Desktop session
|
|
|
|
The host attaches to a **Wayland** desktop session and creates virtual displays in it, so a session
|
|
needs to be running for the user the host runs as. This can be:
|
|
|
|
- a **normal logged-in desktop** (you're sitting at the machine, or it auto-logs-in), or
|
|
- a **headless session** that comes up at boot with no monitor or login — see
|
|
[Running as a Service](/docs/running-as-a-service).
|
|
|
|
Minimum compositor versions (newer is fine):
|
|
|
|
- **KWin ≥ 6.5.6** ([KDE Plasma](/docs/kde)) — headless virtual outputs.
|
|
- **GNOME ≥ 48** ([Mutter](/docs/gnome)) — virtual-monitor screen-cast.
|
|
- **gamescope ≥ 3.16.22** ([Bazzite/Steam](/docs/gamescope)) — older versions deadlock during capture.
|
|
|
|
## Network
|
|
|
|
- Host and client on the **same network** — a LAN, or a VPN that puts them on one subnet. punktfunk
|
|
assumes a trusted local network; it's **not built to be exposed to the public internet — don't
|
|
port-forward it.** To stream from outside your home, use a VPN so the remote client is on the same
|
|
private subnet.
|
|
- For best results, a wired or fast Wi-Fi link. The host can run a built-in **speed test** to pick a
|
|
bitrate for your link (see [Configuration](/docs/configuration)).
|
|
|
|
## A client
|
|
|
|
You also need something to stream *to* — see [Connect a Client](/docs/clients). There are native
|
|
punktfunk clients for **Apple (macOS, iOS, iPadOS, tvOS), Linux, Windows, and Android**, and any
|
|
Moonlight client works too. All of them can discover the host on your network automatically.
