Audio: a headless host has no speakers, and on a LAN with AirPlay devices PipeWire picks a random HomePod as default — so desktop audio (which the host captures from the default sink's monitor) went to a HomePod over AirPlay instead of to the client, and there was no "Punktfunk" output to select. Ship a `punktfunk-sink.conf` (a `support.null-audio-sink` adapter — NOT the non-existent module-null-sink, which makes pipewire refuse to start) with high priority.session so it's the default; run-headless-kde.sh installs it and restarts pipewire once on first install. The host then captures its monitor and streams it. (Disable AirPlay sinks out of band: `dnf remove pipewire-config-raop`.) Input: the host's libei portal D-Bus connection goes stale when the compositor session restarts the portal under it, and the in-process reopen loop can't recover it (EIS setup keeps timing out) — only a full restart does. Add PartOf=punktfunk-kde-session.service so the host restarts with the session. Both verified live on the Fedora 44 KDE box. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# punktfunk streaming host — systemd USER unit (`serve --native` = GameStream + punktfunk/1).
|
|
#
|
|
# Install (against an already-running compositor session):
|
|
# mkdir -p ~/.config/systemd/user && cp scripts/punktfunk-host.service ~/.config/systemd/user/
|
|
# cp scripts/host.env.example ~/.config/punktfunk/host.env # then edit for your backend
|
|
# systemctl --user daemon-reload && systemctl --user enable --now punktfunk-host
|
|
#
|
|
# Self-contained boot appliance (no login, no manual steps after boot):
|
|
# - kwin backend (stream the Plasma desktop): also install + enable
|
|
# punktfunk-kde-session.service (it brings up the headless KWin session this After=s), and set
|
|
# PUNKTFUNK_COMPOSITOR=kwin + WAYLAND_DISPLAY=wayland-kde in host.env.
|
|
# - gamescope backend (stream a nested app, no desktop): set PUNKTFUNK_COMPOSITOR=gamescope in
|
|
# host.env — the host spawns gamescope per session, so no kde-session unit is needed.
|
|
# Then `sudo loginctl enable-linger "$USER"` so user units start at boot, and reboot.
|
|
#
|
|
# The host LISTENS as soon as it starts and only touches the compositor per session (on a client
|
|
# connect), so the After= below is a soft ordering, not a hard readiness gate — the kde-session
|
|
# unit (when present) just needs to be up by the time a client streams (seconds later, user-driven).
|
|
# A missing After= unit (e.g. gamescope backend, no kde-session installed) is simply ignored.
