Desktop-mode (KWin) streaming had no input: the path was libei via the RemoteDesktop portal, which (a) isn't reachable from the host service env and (b) requires a human to approve "Allow remote control?" — a non-starter on a headless box. KWin's own headless RDP server (krdpserver) solves this with org_kde_kwin_fake_input, authorized by the exact same .desktop X-KDE-Wayland-Interfaces grant we already ship (org_kde_kwin_fake_input is listed alongside zkde_screencast_unstable_v1). Add a fake_input injector: vendor the protocol XML, bind the global as an ordinary Wayland client, authenticate (auto-accepted for an interface-authorized client — no dialog), and translate pointer (rel/abs), button, scroll, keyboard (raw evdev keycodes resolved by KWin's own keymap) and touch. Select it for KWin (compositor=="kwin" or XDG_CURRENT_DESKTOP KDE); GNOME stays on libei (it has neither fake_input nor the wlr protocols). PUNKTFUNK_INPUT_BACKEND=kwin forces it. cargo check + clippy + fmt green. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

<description summary="Fake input manager">
|
|
This interface allows other processes to provide fake input events.
|
|
Purpose is on the one hand side to provide testing facilities like XTest
|
|
on X11, but also to support use cases like remote control (a remote
|
|
desktop server). The compositor gates the interface: it is only exposed
|
|
to clients authorized through their .desktop X-KDE-Wayland-Interfaces, so
|
|
binding it is the authorization — no per-event confirmation dialog.

<description summary="Information about the application requesting fake input">
|
|
A FakeInput is required to authenticate itself by providing the
|
|
application name and the reason for fake input. The compositor may use
|

this information to decide whether to allow or deny the request.
