fix(linux): record through a version 1 ScreenCast portal - #1538
Cause
The helper read AvailableCursorModes unconditionally, in offered_cursor_modes() and in negotiate(). That property came with version 2 of the ScreenCast portal, so on a v1 portal every take failed with "AvailableCursorModes: This interface requires version 2, but 1 is available".
Fix (portal.rs, all callers route through it)
A v1 portal offers no cursor modes. CursorMode::resolve turns an empty offer into EMBEDDED, so the take no longer fails on missing METADATA.
On v1, SelectSources is sent without cursor_mode. ashpd 0.9 always sets it, and xdg-desktop-portal rejects any cursor mode a v1 backend did not advertise ("Unavailable cursor mode", validate_cursor_mode in desktop-portal/screen-cast.c). The call is made through ashpd's zbus proxy, subscribed to the Request's Response before the call. No new dependency.
main.rs: on X11, a v1 portal falls back to direct X11 capture, which reports the cursor.
X11 on main
Main already avoids the error on X11, but not through #1492 alone: since 32317eb an X11 take probes the helper, the probe dies on this error without ready, and backendFromProbe then picks direct X11. This PR keeps that result explicitly. Mint Cinnamon runs X11 by default, so the reporter is likely covered on main already. A Wayland session with a v1 portal was still broken; this fixes it.
Tests
cargo test (WSL, rustc 1.94.1): 112 passed. New: a_v1_portal_offering_no_mode_records_embedded, the_request_path_follows_the_sender_name.
cargo clippy --all-targets: no warnings in the changed code. rustfmt --check src/portal.rs: clean.
No TypeScript changed, so the typechecks and lint were not run.
Not verified
A real take on a v1 portal. That needs a desktop session with such a backend, which no reachable machine has. This path is under electron/native/**, so the evidence lock applies.
A v1 portal has no AvailableCursorModes, so reading it failed every take
with "This interface requires version 2, but 1 is available". Such a
portal now offers no cursor modes: the take resolves to EMBEDDED and
SelectSources goes out without cursor_mode, which xdg-desktop-portal
rejects on a v1 backend. On X11 a v1 portal falls back to direct X11
capture, as it already did through the failed probe.
Refs #1537
The ScreenCast flow now handles portals without cursor-mode support. It omits cursor_mode from version 1 source selection, resolves an empty mode list to Embedded, and selects direct X11 capture on X11 when the portal offers no modes.
Version 1 portals use a custom SelectSources request without cursor_mode. The request subscribes to the response signal before the call and maps response codes to success or errors. Version 2 or later continues through ashpd with no restore token and PersistMode::DoNot.
This change fixes recording through version 1 ScreenCast portals, but two gaps remain. Recordings made through a legacy backend may silently lack the cursor while the app reports it as embedded. Newer portal frontends running over older backends can still fail to start a recording. Resolve both before merging.

Do not report an unverified v1 cursor mode as Embedded.
On a v1 portal, the request cannot select a cursor mode. With the legacy GTK backend and Mutter’s hidden default, the recording can omit the cursor while ready reports embedded; no cursor metadata is available for samples. Represent the v1 mode as unknown, or warn before recording when the cursor cannot be guaranteed.

On Wayland, a version 1 backend can produce an empty cursor-mode mask even when the frontend reports version 5. The helper resolves that mask to Embedded, but negotiate rejects it before reaching the cursor-mode-less SelectSources path. Recording fails instead of using the version 1 fallback.

I ran this against a real xdg-desktop-portal 1.18 frontend (the version Mint 22 / Ubuntu 24.04 ship), with a mock v1impl.portal.ScreenCast backend and a PipeWire videotestsrc source, on a private D-Bus session. Helpers built from main (bc11fc4) and this PR (92488c0).
1. A v1 backend behind the 1.18 frontend does not show up as version 1
The frontend advertises its own interface version, not the backend's:
org.freedesktop.portal.ScreenCast version -> u 5
org.freedesktop.portal.ScreenCast AvailableCursorModes -> u 0
So has_cursor_modes() returns true and the new v1 path never runs:
main
this PR
probeOnly
cursor-metadata-unsupported
ready, cursorMode: "embedded"
real take (metadata or embedded)
fails
portal-failed: "the ScreenCast portal does not offer the Embedded cursor mode"
The probe now reports ready, but the take still fails right after it.
Gating on the offered modes, not on the version, fixes that. In negotiate(), right after cursor_modes is read:
// A v1 backend behind a newer frontend shows up as version >= 2 with no modes.let has_cursor_modes = has_cursor_modes && !cursor_modes.is_empty();
With that change, the same setup records end to end. SelectSources goes out as {types: 3, multiple: false} with no cursor_mode, the frontend accepts it, Start grants the node, and the helper writes a valid H.264 MP4 (320×240, 2.87 s, 83 frames). So select_sources_without_cursor_mode works; it just needs the right condition.
2. The reported error message most likely comes from a localized GLib error, not a v1 portal
ashpd::Proxy::new falls back to version = 1 whenever reading version fails with anything it doesn't parse as PortalNotFound. That parsing matches the English GLib text (No such interface “…” on object at path …). GLib translates that message. With a mock frontend that answers the way a French desktop does (InvalidArgs: Aucune interface « org.freedesktop.portal.ScreenCast »):
this PR gives portal-failed: ScreenCast version: org.freedesktop.DBus.Error.InvalidArgs: Aucune interface « … », on both wayland and x11. It is a Failed, not Unavailable, so the helper doesn't fall back to direct X11 capture itself. The app-level backendFromProbe fallback should still apply on X11, as it does on main.
With the English message and no ScreenCast backend, main and this PR both correctly report "no ScreenCast portal is available".
I'd guess the reporter is on a non-English locale with no ScreenCast backend (xapp doesn't implement it), so the portal is effectively missing. It would be worth asking them for locale and echo $XDG_SESSION_TYPE. If that's confirmed, screencast_error and has_cursor_modes could treat a failed version read whose error name is org.freedesktop.DBus.Error.InvalidArgs / UnknownInterface as Unavailable, instead of relying on the message text.
Suggested changes
Take the no-cursor_mode path whenever AvailableCursorModes is empty, not only when version < 2.
Classify a failed version read by D-Bus error name, so a localized "no such interface" becomes Unavailable.
