enricobuehlerandClaude Fable 5	1f59498c5c	fix(host/linux): a no-channel session composites the metadata cursor — Mutter never embeds on a virtual stream ... The capture-latched client (console.rs latched_mouse) never advertises CLIENT_CAP_CURSOR, so its session resolved cursor_blend=false and asked Mutter to EMBED the pointer. On a Mutter virtual stream that is a fiction: since Mutter 48 (7ff5334a, hw-cursor inhibition removed) the software cursor overlay is suppressed stage-globally whenever any physical head realizes a HW cursor — dmabuf-recorded frames blit the view without a pointer, and cursor-only motion schedules no re-record either (mutter#4939). Probed on-glass on Mutter 50.3: embedded + relative motion = frozen frame counter; SPA_META_Cursor positions kept flowing in the same setup. So the no-channel session now takes the path that was verified end to end: cursor-as-metadata + the host composites, permanently — the same arm a channel session lands in after its capture-model flip. Embedded remains only the can't-blend fallback (libav VAAPI/NVENC, software). - session_plan::cursor_blend_for grows the no-channel arm (codec + depth in, the same CUDA-payload prediction handshake makes); gamescope excluded so patch-2+ keeps its native-NV12 zero-copy shape - the encode loop's composite refresh + one-shot breadcrumbs now cover the no-channel session; the park schedule keeps retrying while its composite is starved (relative-only clients cannot park themselves) - the compositor retarget re-applies set_hw_cursor — the rebuilt display used to come up EMBEDDED even for channel sessions - the GameStream virtual source takes the same rule (it never has a channel); its stream_body blend flag mirrors the request - punktfunk-probe grows --cursor-nochannel (the latched-capture client, headless); cursor-probe grows --dump (PPM frames + a content-change counter, the pixel evidence the embedded A/B lacked) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-30 00:35:25 +02:00
enricobuehlerandClaude Opus 5	787756e68b	test(vdisplay/mutter): the on-glass lever for the GNOME backend, and what it took to see the leak ... `live_mutter_create_drop`, `#[ignore]`d in the same convention as the Windows backend's live tests: the real four-step handshake, hold, then drop the keepalive and let the RAII teardown revert it. Verified against gnome-shell on 192.168.1.21 — node_id came back in ~5 ms, preferred_mode as asked, and the topology reverted. Two things that would otherwise be re-derived by whoever validates this next, both of which cost a wrong answer here first. The virtual monitor does NOT appear in DisplayConfig's GetCurrentState just because `create` succeeded — its size follows the PipeWire negotiation, so without a consumer attached there is no monitor to census. A before/after monitor diff therefore proves nothing about this backend, which is the trap the first attempt fell into. And a short-lived process cannot exhibit the abandoned-thread leak at all: exiting drops the D-Bus connection, which makes Mutter tear the session down no matter which code is running. Reproducing it needs the process held alive past the failed create, and the observable is the live RemoteDesktop session object, not the monitor: `gdbus introspect -d org.gnome.Mutter.RemoteDesktop -o /org/gnome/Mutter/RemoteDesktop` lists a `node Session` child per live session. With a 1 ms create timeout forced and the process held 20 s, that probe reads 0 with b89a36a6 and 1 without it — the orphan thread parked on a live session. Both read 0 after exit, which is precisely why this only ever bit a long-running host. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-28 19:45:11 +02:00
enricobuehlerandClaude Opus 5	69bc92afed	fix(vdisplay/mutter): a create timeout no longer abandons the session thread with the desktop dark ... `create` gave up after 45 s and dropped its `stop` flag WITHOUT setting it — the `StopGuard` that owns the only `store(true)` was built on the success path only. The thread meanwhile discarded its own send failure with `let _ =`, so it sailed past the dead channel, made the virtual output PRIMARY, and parked in `while !stop` for the rest of the process's life holding the D-Bus connection that IS the monitor's lifetime. Its teardown was unreachable. Under the default topology that orphan applies a SOLE-monitor APPLY_TEMPORARY config. Every physical head goes dark, and Mutter reverts such a config only once the virtual monitor disappears — which the parked thread prevents. There is no in-process recovery: each retry adds another orphan and another virtual monitor. The other three portal/D-Bus backends never had this — kwin.rs, hyprland.rs and wlroots.rs all `?` on that exact send. Mutter is now the same shape, via a shared `report_node` that stops the session when the opener has gone. Two more layers behind it, because the send can also LAND in the moment `recv_timeout` gives up: `create` and `stream_existing_output` build their guards BEFORE the wait, so every error arm signals the thread on its way out, and the thread re-checks the flag before it touches topology — so a doomed session never applies a sole-monitor config at all, rather than applying one and reverting it a tick later. The fix lands once because the duplication that caused it is gone first: `connect` and `connect_monitor` shared ~72 verbatim lines, and the mirror path repeating the session path's `let _ = send` is precisely what that copy bought. Both now share `open_rd_sc` (steps 1-2) and `start_and_await_node` (step 4). Also stops a physical hotplug stealing the virtual monitor's identity. `wait_virtual_connector` took "any connector absent from the pre-snapshot" across a window spanning a ~10 s stream wait plus 6 s of polling; TOPOLOGY_LOCK keeps sibling sessions out of it but a hotplug is not ours to serialise, and the session's topology apply and scale persistence would then be aimed at the operator's new panel. It now prefers the connector advertising the client's exact WxH — the discriminator `make_virtual_primary` already matches on — falls back to the old behaviour when that singles nothing out, and warns when more than one candidate appears. Tests: `pick_virtual` split out of the polling loop so the choice is testable without a session bus. Verified on Linux (192.168.1.25): 99 passed, and the hotplug case FAILS against the old first-new-connector logic, so it is not vacuous.

enricobuehler	0868b6a364	fix(vdisplay): compositor availability follows the live session, not the env ... GNOME/Mutter reported "Unavailable" on a host sitting in a live Mutter session — and, on the same request, "Default", because the two columns had different sources. available() asked each backend, and those probes read the process env (XDG_CURRENT_DESKTOP for Mutter, WAYLAND_DISPLAY for KWin's registry handshake, SWAYSOCK for sway) — env a host started outside the session (systemd --user, a TTY, ssh) never inherited. It is only retargeted at the live session on the connect path, so the answer also flipped depending on whether anyone had connected yet. Both columns now come from the same /proc scan detect() already used: the live session's compositor is usable by definition, as is an explicit operator pin, and the per-backend probe stays as the fallback for backends that are not the live session (gamescope, which spawns its own). A live KWin without the zkde_screencast grant now surfaces as available and fails at create with that probe's precise message, which beats "no usable compositor" on a box visibly running KDE. Mutter's env sniff stays deliberately narrow — one var, not three. XDG_CURRENT_DESKTOP is the one apply_session_env owns end to end (written per connect, scrubbed when nothing is live); sniffing DESKTOP_SESSION alongside would resurrect the bug that scrub exists to prevent, where a stale value after a gnome-shell crash routes the next client into a dead session. Non-Linux hosts now report no compositors at all rather than five Linux backends flagged unavailable with no default — on Windows the pf-vdisplay driver is the only backend and vdisplay::open ignores the argument, so the old list read as broken detection instead of "not applicable here". The console says so explicitly. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com> (cherry picked from commit eb7ba3d6177552f5c3ed6a15439404084869c636)	2026-07-28 17:01:59 +02:00
enricobuehlerandClaude Opus 5	b08226dbf1	feat(vdisplay): mirror a pinned monitor on sway and Hyprland ... P5 of design/per-monitor-portal-capture.md, and the end of a hole worth naming: the pin was accepted, persisted and offered in the console while `create` bailed on these two backends, so a sway or Hyprland host with a monitor selected failed EVERY session. Both already ship the mechanism — a managed portal-chooser config plus a per-session selection file (xdpw's `Monitor: NAME`, xdph's `[SELECTION]screen:NAME`) — so mirroring is that same chooser pointed at a physical connector instead of a headless output we created. The keepalive stops the cast and nothing else; the monitor is the compositor's. The selection write is now serialized against the handshake that reads it (SELECTION_LOCK, applied to the virtual-output paths too). That file is one per-user path: whoever writes last before the portal reads wins, and the loser does not fail — it silently captures the other session's output. `managed` is no longer grounds for refusal everywhere. It is conclusive only where the name is ours by construction (KWin's `Virtual-punktfunk`, Hyprland's `PF-N`); sway names EVERY headless output `HEADLESS-N`, its own included, so the old rule would have refused to mirror any output on a headless sway box — exactly the remote setup this feature serves. Found on-glass, and now a test. Verified on a two-output headless sway: asking for HEADLESS-1 yields 1280x720 frames and HEADLESS-2 yields 1920x1080, so the chooser really does steer per request. Hyprland is compile-only — no Hyprland box exists. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>	2026-07-27 23:51:41 +02:00
enricobuehlerandClaude Opus 5	bf2f54a5fe	feat(vdisplay): mirror a pinned monitor on Mutter, and scope the HDR probe ... P3 of design/per-monitor-portal-capture.md. Mutter's mirror is the same private ScreenCast session the virtual path already drives, one call different — RecordMonitor instead of RecordVirtual — so it inherits what makes that path work headlessly: a direct D-Bus API that needs no interactive approval, unlike the xdg portal a background service could never answer. Deliberately not under TOPOLOGY_LOCK: that serializes operations which add or remove a monitor or apply a monitor configuration, and mirroring does neither. Nothing is created, no layout changes, and teardown is just Stop — the SIGSEGV-adjacent ordering the virtual path must observe cannot arise when no monitor is being removed. The GNOME HDR probe now honors the pin. Asking "is ANY monitor in BT.2100 mode" was fair while capture took whatever head it was handed; once the operator names one, an HDR TV on the next connector must not talk the host into offering PQ formats for the SDR panel it is actually streaming. A pin that names no live head reports SDR rather than falling back to "any" — the session is about to fail on that same missing monitor, and an over-claimed HDR offer would be a second, quieter wrong answer. ⚠️ RecordMonitor's exact signature is read from the interface, not yet confirmed against a live gnome-shell; no GNOME box was reachable.

enricobuehlerandClaude Opus 5	53c772702f	feat(host): list-monitors CLI, and two bugs it caught on-glass ... An operator configuring an unattended host has to learn the connector names from somewhere, and "curl the management API before the host is configured" is not it. `punktfunk-host list-monitors` prints them with geometry and flags the pinned one. Running it under a real sway immediately caught two defects the unit tests could not: - the query used the `swaymsg` command helper, which inserts `--`, so `-t get_outputs` came back as "Unknown/invalid command '-t'". Queries now go through a `swaymsg_query` helper that cannot make that mistake. - compositors write the literal "Unknown" rather than leaving make/model empty, so the picker label read "Unknown Unknown". One `describe` helper now treats that as absent, for all four backends. Verified on a headless two-output sway: names, modes, positions, scale and the case-insensitive pin all resolve.

enricobuehlerandClaude Opus 5	95e3314d9a	feat(vdisplay): enumerate the host's physical monitors ... P0 of per-monitor capture (design/per-monitor-portal-capture.md): nothing in the tree could answer "what heads does this host have?", which both a monitor pin and a console picker need first. One read per compositor, each beside the code that already speaks that dialect: KWin's kde_output_device_v2 (the topology session now also records geometry + scale), Mutter's DisplayConfig.GetCurrentState, swaymsg get_outputs, hyprctl monitors. Logical geometry throughout, because x/y is what identifies a head — two monitors can share a size but never an origin. PUNKTFUNK_CAPTURE_MONITOR parses here and is reported at startup, loudly including that it is not yet enforced: a knob that is read but inert has to say so, or "it didn't work" reads as a bug. GET /display/monitors always answers 200 with an explained empty list, so a compositor-less host renders as "nothing to pick", not as a broken console.

enricobuehlerandClaude Fable 5	925130d1f9	feat(vdisplay): compositor-embedded pointer for sessions without the cursor channel (Phase B) ... Since the cursor-channel work, every Linux virtual output was created in metadata pointer mode — making ALL sessions depend on host-side cursor compositing, including the ones that can never use the channel (Moonlight/ GameStream, legacy clients, capture-mode starts). Those sessions paid the blend bring-up per session and, whenever a visible cursor was composited, the loss of NVENC's stream-ordered submit — for a strictly worse cursor than the compositor's own. Mirror the Windows no-regression gate: the already-wired per-session set_hw_cursor(cursor_forward) now drives the Linux backends too. A cursor-channel session gets metadata (shapes forwarded, composite flip blends host-side — today's validated path, unchanged); every other session gets the pointer compositor-EMBEDDED at creation (KWin zkde pointer=2, Mutter cursor-mode=1, wlroots/hyprland portal CursorMode::Embedded — their pre-channel default; the portal pair also gains the Metadata arm for channel sessions, wired but untested on-glass). SessionPlan.cursor_blend narrows to cursor-forward sessions and rides into the direct-SDK NVENC open, which skips the Vulkan slot-blend bring-up entirely when off — embedded sessions ring on plain CUDA surfaces and pay zero cursor cost, per-session or per-frame. The keep-alive registry's reuse key grows the created pointer mode (new VirtualDisplay::hw_cursor getter): a kept embedded display has no cursor metadata for a channel session to forward, and a kept metadata display would leave a channel-less session with no pointer in its frames.

enricobuehlerandClaude Fable 5	315ffaf144	fix(linux/vdisplay): mutter virtual monitor ships the cursor as SPA_META_Cursor ... RecordVirtual was created with cursor-mode EMBEDDED, which never delivers cursor metadata — the cursor channel had nothing to forward (client-drawn cursor invisible) and the always-built encoder blend had nothing to composite (host-drawn cursor invisible too). Metadata mode feeds both: non-forwarding sessions get the blended pointer (same pixels Mutter would have embedded), forwarding sessions strip the overlay and send shape/state. The capturer already negotiates the meta on every stream (meta_param). Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>	2026-07-22 23:43:23 +02:00
enricobuehlerandClaude Opus 4.8	86d9f49473	style(pf-vdisplay): rustfmt under the pinned 1.96.0 toolchain ... The W6.2 pf-vdisplay extraction (27a5d8da) committed six spots that the pinned rustfmt (rust-toolchain.toml = 1.96.0) reformats — a short closure collapse and chain-call wrapping. No semantic change; makes cargo fmt --all --check green so the combined push does not land CI red on pre-existing format drift.

enricobuehlerandClaude Opus 4.8	27a5d8daac	refactor(host/W6.2): extract virtual-display orchestration into the pf-vdisplay crate ... vdisplay.rs + vdisplay/* (the per-compositor Linux backends — KWin zkde-screencast, wlroots swaymsg, Mutter RemoteDesktop, Hyprland — and the Windows IddCx/pf-vdisplay driver backend, behind one VirtualDisplay trait; the mode-conflict admission registry, the display policy/identity/custom-preset state, and the session-env / gamescope routing) move into crates/pf-vdisplay (plan §W6). The DDC/CI panel-power control (used only here) and the KWin zkde protocol XML move with it. This completes the host-crate decomposition: capture, encode, inject, and vdisplay are now four subsystem crates over the shared leaves, and punktfunk-host is the orchestrator (serve/supervisor + native + gamestream + mgmt). Coupling breaks (all down-only, cargo-tree acyclic): - capture::dxgi identity -> pf_frame::dxgi; win_display/monitor_devnode/ console_session_mismatch -> pf-win-display leaf; can_open_another_session -> pf-encode (the NVENC session-budget admission gate — acyclic peer edge). - The registry's DisplayCreated/DisplayReleased emits into the host SSE event bus invert to a leaf hook: pf-vdisplay emits a neutral DisplayEvent to a host-registered DISPLAY_EVENT_SINK, so it never reaches the orchestrator's events module. - The IddCx driver module is renamed pf_vdisplay -> driver (its old name collided with the crate name through the host's `mod vdisplay` shim glob). The host keeps `mod vdisplay { pub use pf_vdisplay::* }` so every crate::vdisplay::* path (serve/mgmt/native/the capture FrameChannelSender seam) is unchanged; the heavy deps (wayland/ashpd/tokio + the zkde protocol) moved with the crate. Co-authored: a fail-closed IOCTL-reply-length security fix (reject short/zeroed pf-vdisplay driver replies before trusting protocol_version/target_id/wudf_pid/luid, security-review 2026-07-17) rides this commit in the moved driver module. Verified: Linux clippy -D warnings (pf-vdisplay + host nvenc,vulkan-encode,pyrowave --all-targets) + pf-vdisplay 63/63 + host 167/167 tests; Windows clippy -D warnings (pf-vdisplay --all-targets + host nvenc,amf-qsv --all-targets) Finished exit 0.
