MSIX (the client's format) can't install the host's LocalSystem secure-desktop service or the SudoVDA kernel driver, so the host ships as a signed Inno Setup setup.exe that runs elevated and delegates to the existing idempotent `punktfunk-host service install`. - packaging/windows/punktfunk-host.iss: lay exe into Program Files, optional SudoVDA driver task, run service install/start; [Code] stops+waits the service before file copy on upgrade; uninstall runs service uninstall. - pack-host-installer.ps1: cert (reuses MSIX_CERT_PFX_B64 / self-signed CN=unom), sign inner exe + setup.exe, fetch/stage SudoVDA, run ISCC, export public .cer. - fetch-sudovda.ps1 / install-sudovda.ps1: pinned SudoVDA + nefcon download, cert import, gated device-node create (no phantom dup), pnputil install (warn-not-abort). - nvenc/: synthesize nvencodeapi.lib via llvm-dlltool from a 2-export .def so --features nvenc links with no GPU/SDK at build time. - .gitea/workflows/windows-host.yml: build (nvenc) -> clippy -> ISCC -> sign -> publish setup.exe + .cer to the generic registry pkg punktfunk-host-windows. Tag host-win-v* -> X.Y.Z (+ latest/ alias); main push -> rolling 0.2.<run>. - setup-windows-runner.ps1: provision Inno Setup; docs: installer instructions. SudoVDA/nefcon release URLs+SHA-256s in fetch-sudovda.ps1 are placeholders (baseline v0.2.1) — fetch warns + prints the computed hash until pinned.

title: Running as a Service
|
|
description: Start the host at boot — for a desktop you log into, or a fully headless always-on machine.
|
|
---
|
|
|
|
Running `serve --native` in a terminal is fine for trying punktfunk out. To make a machine an
|
|
always-available host, run it as a service. There are two cases.
|
|
|
|
## A. A desktop you log into
|
|
|
|
If you sit at the machine (or it auto-logs-in to a desktop), run the host as a **systemd user
|
|
service** that starts with your session:
|
|
|
|
```sh
|
|
mkdir -p ~/.config/systemd/user
|
|
cp scripts/punktfunk-host.service ~/.config/systemd/user/
|
|
# Put your host.env in place first — see the setup guide for your desktop.
|
|
systemctl --user daemon-reload
|
|
systemctl --user enable --now punktfunk-host
|
|
```
|
|
|
|
The host now starts whenever you log in. Check it with `systemctl --user status punktfunk-host`.
|
|
|
|
## B. A headless, always-on host
|
|
|
|
To run with **no monitor and no login** — a machine in a closet that's always ready — you need two
|
|
things: a desktop session that comes up at boot, and the host service started without a login.
|
|
|
|
Start by making the host service start at boot even when nobody logs in:
|
|
|
|
```sh
|
|
sudo loginctl enable-linger "$USER"
|
|
```
|
|
|
|
Then bring up a session automatically, depending on your desktop:
|
|
|
|
### Headless GNOME
|
|
|
|
Have GDM auto-login your user, so a GNOME Wayland session is always running:
|
|
|
|
```ini
|
|
# /etc/gdm3/custom.conf (Ubuntu) · /etc/gdm/custom.conf (Fedora)
|
|
[daemon]
|
|
AutomaticLoginEnable = true
|
|
AutomaticLogin = your-user
|
|
```
|
|
|
|
Then **disable the screen lock** — a locked GNOME session blocks screen capture, and there's no one to
|
|
unlock a headless box:
|
|
|
|
```sh
|
|
gsettings set org.gnome.desktop.screensaver lock-enabled false
|
|
gsettings set org.gnome.desktop.session idle-delay 0
|
|
```
|
|
|
|
Enable the host user service (section A) and reboot. The host comes up on the auto-login session.
|
|
|
|
### Headless KDE
|
|
|
|
punktfunk ships a unit that brings up a headless KWin/Plasma session with no display manager, so the
|
|
host has a desktop to stream even with no monitor attached:
|
|
|
|
```sh
|
|
cp scripts/punktfunk-kde-session.service scripts/punktfunk-host.service ~/.config/systemd/user/
|
|
# host.env: PUNKTFUNK_COMPOSITOR=kwin, WAYLAND_DISPLAY=wayland-kde
|
|
systemctl --user daemon-reload
|
|
systemctl --user enable punktfunk-kde-session punktfunk-host
|
|
sudo loginctl enable-linger "$USER"
|
|
reboot
|
|
```
|
|
|
|
The session unit starts headless KWin; the host unit follows it and starts listening. (KWin only needs
|
|
to be up by the time a client connects, so the ordering is soft.)
|
|
|
|
### Headless Bazzite
|
|
|
|
On Bazzite, the host launches its own gamescope/Steam session per client, so you don't need a separate
|
|
session unit — see [Bazzite](/docs/bazzite).
|
|
|
|
## Windows
|
|
|
|
On Windows the host runs as a `LocalSystem` service that launches into the interactive session, so it
|
|
captures the secure desktop (UAC / lock screen) and survives reboots with nobody logged in — the same
|
|
model Sunshine/Apollo use.
|
|
|
|
The easy path is the **signed installer**: download `punktfunk-host-setup-<ver>.exe` from the package
|
|
registry ([`punktfunk-host-windows`](https://git.unom.io/unom/-/packages)) and run it. It drops the host
|
|
into `C:\Program Files\punktfunk`, optionally installs the bundled **SudoVDA** virtual-display driver,
|
|
and registers + starts the service for you (`/VERYSILENT` for unattended). Upgrades and uninstall are
|
|
handled through Add/Remove Programs.
|
|
|
|
Prefer the CLI? Run `punktfunk-host service install` from an elevated prompt — see
|
|
[Windows service](https://git.unom.io/unom/punktfunk/src/branch/main/docs/windows-service.md). Either
|
|
way you need an NVIDIA GPU + driver (the host is NVENC-only on Windows).
|
|
|
|
## Verifying
|
|
|
|
After a reboot, from another machine on the network:
|
|
|
|
```sh
|
|
punktfunk-probe --discover # or just look for the host in the Apple app / Moonlight
|
|
```
|
|
|
|
If the host is listed, it's up. If not, check `journalctl --user -u punktfunk-host` on the host.
