enricobuehler	61aa1053e7	feat(host/gamescope): headless game mode that follows the box + matches the client ... Make Steam game mode work on a display-less streaming host and stream it at the client's resolution: * Ship /etc/gamescope-session-plus/sessions.d/steam (packaging/bazzite/ gamescope-headless-session, installed by the RPM + Arch PKGBUILD): fall back to gamescope's headless backend when no display is connected, so "Switch to Game Mode" boots offscreen instead of crashing on the missing panel (and 5-striking back to desktop). No-op on display-attached boxes; only sets unset values so the host's per-client mode still wins. * Default Bazzite/SteamOS to ATTACH (PUNKTFUNK_GAMESCOPE_ATTACH=1 in host.env): the box owns its session (Desktop<->Game, persistent), the host follows + captures it and never tears it down — so switching is rock-solid and a disconnect leaves the box in its mode (reconnect returns there). * Resize-on-attach (gamescope.rs): on connect, ensure the box's own game-mode session runs at the CLIENT's resolution — reuse it when already matching (fast path, no restart), else reconfigure + restart the box's own autologin gamescope-session-plus@<client> at the client mode (cooperative: no competing unit, so no autologin-respawn fight). Detect the live gamescope's -W/-H via argv[0] in /proc (its /proc/<pid>/exe is unreadable for that process). Validated live on a headless bazzite-deck-nvidia box: game mode boots headless + stable (0 strikes); the host attaches + streams video/audio/EIS input; a 5120x1440 client reuses the matching session and streams at 5120x1440.

enricobuehler	32c1929948	feat(host/session-watch): default Gaming↔Desktop follow on for Bazzite/SteamOS ... The mid-stream session watcher (rebuild the backend in place when the box flips Gaming↔Desktop) was opt-in via PUNKTFUNK_SESSION_WATCH, so it never ran on a stock Bazzite/SteamOS box — switching modes froze the stream on the now-dead compositor. Default it ON when os-release ID/ID_LIKE is bazzite/steamos (the platforms that flip sessions); still off on plain desktops. Also parse the env properly so PUNKTFUNK_SESSION_WATCH=0 actually disables it (was: any value, including "0", enabled it).

enricobuehler	f869b434ba	fix(host): input follows session per-connect + restore-guard on desktop switch ... Two fixes from live Bazzite testing of the managed-Gaming + mid-stream work: 1. Input now FOLLOWS the active session. The host-lifetime injector was pinned to the first backend it opened and only reopened on an inject FAILURE — but with Feature A keeping the managed gamescope warm, its EIS socket stays alive, so a switch to the KDE desktop + reconnect kept injecting into the idle gamescope (input silently dead on KDE). injector_service_thread now compares the resolved input backend (default_backend() ← PUNKTFUNK_INPUT_BACKEND, set per connect by apply_input_env, and on a mid-stream switch) each event and reopens when it changes. Fixes input on a Gaming->Desktop reconnect AND Feature B's mid-stream input re-route, with no plumbing. 2. Debounced TV-restore no longer yanks you back to gaming. do_restore_tv_session now checks detect_active_session(): if a desktop session is active (the user switched), it tears down the idle managed gamescope but does NOT restart the gaming autologin. Observed live: the restore fired and restarted gamescope-session-plus@ogui-steam while the client was already on the KDE desktop. Also: document PUNKTFUNK_SESSION_WATCH (Feature B opt-in) in the Bazzite host.env and correct the managed-default description. Compiles, clippy/fmt clean, 78 tests.

enricobuehler	c25706b355	feat(host/gamescope): managed-default Gaming with debounced TV-restore ... Feature A: in Gaming Mode, default to a host-managed gamescope at the CLIENT's mode (tear the TV's autologin down on connect) instead of attaching to the running TV session — so the client receives ITS resolution (capture == encode == client mode, fixing the InitializeEncoder size mismatch the attach path hit), not the TV's 4K. Reliability is the debounce: restore_managed_session() now SCHEDULES the TV restore RESTORE_DEBOUNCE (5s) after the last disconnect via a host-lifetime worker, instead of restoring immediately per-disconnect. A reconnect inside the window cancels the pending restore and reuses the still-warm managed session (create_managed_session clears PENDING_RESTORE at the top) — so a quick reconnect (e.g. a controller hiccup) never triggers a gamescope stop/relaunch, which is the per-connect churn that leaked NVIDIA GPU context on F44 (the black-screen reconnect). - vdisplay/gamescope.rs: PENDING_RESTORE + RESTORE_DEBOUNCE; schedule_restore_tv_session (debounced), do_restore_tv_session (the actual restore, worker-driven), start_restore_worker (100ms tick, RAII keepalive handle). create_managed_session cancels the pending restore + reuse path unchanged. - vdisplay.rs: apply_input_env flips gamescope to managed-DEFAULT; PUNKTFUNK_GAMESCOPE_ATTACH (or an explicit _NODE) opts back to attach for couch-on-TV; _MANAGED forces managed. restore_managed_session schedules; new start_restore_worker wrapper. - m3.rs serve(): hold the restore worker for the host lifetime. - bazzite host.env: document managed-default + the ATTACH opt-out. Compiles, clippy-clean, 78 host tests pass. F44 single stop/start leak to be verified live on the box. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 22:34:33 +00:00
enricobuehler	6f77574876	feat(host/vdisplay): per-connect active-session backend selection ... Bazzite/SteamOS boxes flip between Steam Gaming Mode (gamescope) and a KDE/GNOME desktop. The host statically read PUNKTFUNK_COMPOSITOR / XDG_CURRENT_DESKTOP once, so switching to Desktop Mode failed the stream, and the gamescope managed-session path stopped+relaunched the autologin per connect — leaking GPU context on F44 (reconnect → black screen). Replace the static read with a runtime probe of the live session and route each connect to the right backend, churn-free: - vdisplay::detect_active_session() probes /proc for the running compositor of our uid (gamescope|kwin_wayland|gnome-shell|sway, desktop outranks a leftover gamescope) + scans the runtime dir for the live wayland-* socket. Returns an ActiveKind + the SessionEnv (WAYLAND_DISPLAY/XDG_RUNTIME_DIR/DBUS/ XDG_CURRENT_DESKTOP) that targets it. - apply_session_env() writes that into the process env per connect (host serves one session at a time), so every backend (capture + input) opens against the live session; apply_input_env() points input at the matching backend and selects gamescope ATTACH (no managed restart) unless PUNKTFUNK_GAMESCOPE_MANAGED. - resolve_compositor() (native path) auto-detects + applies; explicit PUNKTFUNK_COMPOSITOR still wins (legacy/CI/forcing). detect() is now active-aware for the GameStream/mgmt callers too. - Bazzite host.env drops the static gamescope force; documents auto-detection + the optional overrides. Result: Desktop Mode → KWin/Mutter virtual output at the client's mode (churn-free, the reliable path); Gaming Mode → attach to the running gamescope (no SIGSEGV/GPU leak on reconnect). Compiles + clippy-clean; 78 host tests pass. Live validation on the Bazzite box pending (box offline). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-06-14 21:41:51 +00:00
enricobuehler	23bb814bac	feat(packaging): Fedora/Bazzite packaging — COPR RPM, bootc image, gamescope-default config ... Roadmap #3 (install on other devices). Bazzite already ships gamescope + PipeWire + the NVIDIA stack, so the host slots in with minimal new deps (ffmpeg-libs from RPM Fusion + opus + libei). - packaging/rpm/punktfunk.spec — builds punktfunk-host from source (cargo), installs the binary + udev rule + systemd user unit + headless helpers; Requires/Recommends mapped from the Ubuntu bootstrap deps to Fedora. - packaging/bootc/Containerfile — layer punktfunk into a bazzite-nvidia bootc image for atomic, image-based installs. - packaging/bazzite/host.env — gamescope-default appliance config (spawned per session). - packaging/copr/ + packaging/README.md — COPR build-from-SCM settings + install docs (rpm-ostree and bootc paths), and why not Flatpak. - LICENSE-MIT + LICENSE-APACHE — materialize the declared `MIT OR Apache-2.0` (was unfiled); the RPM ships them. Not buildable on the Ubuntu dev box (no rpm tooling) — the COPR/Fedora build is operator-run; all spec-referenced files verified present and the cargo build is green.
