# punktfunk host configuration (~/.config/punktfunk/host.env) — consumed by punktfunk-host.service.

# The compositor + input backend are AUTO-DETECTED per connect from the live session (the host
# probes which compositor is actually running and retargets WAYLAND_DISPLAY/XDG_CURRENT_DESKTOP/
# DBUS at it), so a box that flips between Steam Gaming Mode and a KDE/GNOME desktop is followed
# automatically. The blocks below are OPTIONAL OVERRIDES — uncomment one only to force a backend
# (this also skips the per-connect env retargeting). The anchors XDG_RUNTIME_DIR + DBUS stay.

# Session / compositor environment (headless KWin example).

# Video source: `virtual` creates a per-client virtual output at the client's exact

# --- Bazzite / SteamOS-like host: host-managed Steam-Deck-UI session -----------------------
# The host LAUNCHES gamescope-session-plus headless AT THE CLIENT'S mode (so games see the
# client's exact resolution + refresh, not the box's TV), and relaunches it when the mode
# changes. Requires the headless-appliance prereqs (linger + multi-user.target — see
# punktfunk-steam-session.service header) and NO physical gaming session running.
#PUNKTFUNK_COMPOSITOR=gamescope
#PUNKTFUNK_GAMESCOPE_SESSION=steam   # host owns a gamescope-session-plus session at the client mode

# Mutually exclusive with the above: ATTACH to a gamescope session something ELSE owns (fixed mode):
#PUNKTFUNK_GAMESCOPE_NODE=auto       # discover + capture a running gamescope (do NOT combine with SESSION)

# --- GNOME / Mutter host (e.g. an Ubuntu desktop) -----------------------------------------
# Attach to a running GNOME (Wayland) session — its default socket is wayland-0, not wayland-kde.
# Mutter creates the per-client virtual output via its `RecordVirtual` D-Bus API (a virtual
# monitor alongside any real one), and input goes through the RemoteDesktop portal (libei). On a
# real desktop the host runs as the logged-in user; headless GNOME also works (gnome-shell
# --headless). Needs GNOME ≥ 48 for the zero-copy RecordVirtual path.

#PUNKTFUNK_MDNS=0                   # disable the mDNS adverts (native + GameStream) — for multicast-
                                    # dead networks/containers; clients add the host by address instead
# Display-management policy (keep-alive · topology · conflict · identity · layout · max) is set in the
# web console (Host → Virtual displays) → ~/.config/punktfunk/display-settings.json, NOT here; a
# settings file supersedes the legacy PUNKTFUNK_MONITOR_LINGER_MS / _NO_ISOLATE / *_VIRTUAL_PRIMARY
# knobs. One transport knob has no console equivalent:
#PUNKTFUNK_IDLE_TIMEOUT_MS=8000     # disconnect-detection latency: how long before a DROPPED client is
                                    # declared gone (a kept display then starts its linger, or frees).
                                    # Lower (e.g. 3000) to reclaim kept displays sooner after an
                                    # ungraceful drop; clamped ≥1s, keep-alive ping scales with it so a
                                    # live session never false-disconnects. A deliberate quit is instant.
# Session recovery hook: fired (debounced, ≥60 s apart) when a client connects while NO graphical
# session is live for this uid — e.g. a compositor crash dropped the box to the GDM greeter, whose
# auto-login only runs once per boot, so the box would otherwise need a walk-up login or a reboot.
# Restarting the display manager re-runs auto-login and the client's retry lands in the recovered
# desktop. Runs detached via `sh -c` as the host's user, so it needs passwordless privilege for
# exactly this action (sudoers drop-in: `youruser ALL=(root) NOPASSWD: /usr/bin/systemctl restart
# gdm`, or a polkit rule + plain `systemctl restart display-manager`). Unset = disabled.
#PUNKTFUNK_RECOVER_SESSION_CMD=sudo -n systemctl restart gdm
