- [x] `/scheme/drm/card0` — endpoint defined in redox-drm; accessibility requires runtime validation
- [x] `KWIN_DRM_DEVICES` — wired in config/redbear-full.toml service environment; runtime proof requires QEMU with DRM
- [x] `redbear-greeter-compositor` — DRM wait logic implemented; logs reflect backend choice at runtime
- [ ] QEMU VNC framebuffer shows the Qt6/QML greeter UI (not bootloader menu)
**Estimated effort:** 3–5 days (pcid matching + DRM device node plumbing + env wiring)

### 3.3 Blocker C: Wire the Qt6/QML greeter UI
**Priority:** P1 — requires Blocker B resolved first.
**Symptom:** Text login prompt only. The greeter compositor starts but the Qt6/QML UI never renders.
**Root cause chain:**
1. KWin compositor needs a DRM backend to create a Wayland display (→ Blocker B)
2. `redbear-greeterd` starts the compositor, waits for Wayland socket, then launches `redbear-greeter-ui`
3. If compositor uses virtual backend, the greeter UI may still try to connect to a Wayland display that doesn't exist or lacks rendering
4. Qt6 plugin path and QML import path must be correct for the greeter UI to load
**Files to verify/modify:**
| File | Check/Change | Why |
|------|-------------|-----|
| `local/recipes/system/redbear-greeter/source/src/main.rs` | Verify greeterd waits for compositor Wayland socket before launching UI | Race condition if UI starts before compositor is ready |
| `local/recipes/system/redbear-greeter/source/redbear-greeter-compositor` | Verify `WAYLAND_DISPLAY` is exported and matches what the UI expects | UI connects to compositor via this socket |
| `local/recipes/system/redbear-greeter/source/ui/main.cpp` | Add diagnostic logging: "UI started, connecting to compositor..." | Visibility into UI launch |
| `local/recipes/system/redbear-greeter/source/ui/Main.qml` | Verify Qt6 QML imports resolve at runtime | Missing QtQuick/QtWayland imports cause silent failure |
| `local/recipes/system/redbear-greeter/recipe.toml` | Verify Qt plugin, QML, and asset paths in `package.files` | UI binaries need Qt runtime files staged in sysroot |
**Acceptance criteria:**
- [ ] `redbear-greeterd` logs "compositor ready, launching greeter UI"
- [ ] `redbear-greeter-ui` process appears in `ps`
- [ ] Qt6/QML greeter login screen visible on the display (QEMU VNC)
- [ ] Text input field accepts username, password field accepts password
- [ ] Login attempt reaches `redbear-authd` (visible in authd logs)
**Estimated effort:** 3–5 days (compositor-to-UI handoff + Qt runtime path validation)

### 3.4 Blocker D: Session handoff after successful login
**Priority:** P1 — requires Blocker C resolved first.
**Symptom:** Unknown — haven't reached this stage yet. Expected gap: after `redbear-authd` authenticates, `redbear-session-launch` starts the KDE session but KWin/Plasma may fail.
**Files to verify:**
| File | Check | Why |
|------|-------|-----|
| `local/recipes/system/redbear-authd/source/src/main.rs` | `start_session()` flow: does it call session-launch correctly? | Authd initiates the session launch after successful auth |
| `local/recipes/system/redbear-session-launch/source/src/main.rs` | Verify uid/gid drop, env setup, `dbus-run-session` invocation | Session needs correct user context and D-Bus session bus |
| `config/wayland.toml` | Verify canonical KWin launch env (`KWIN_DRM_DEVICES`, `XDG_RUNTIME_DIR`, `QT_*` paths) | KWin session needs same DRM/seat/Qt env as greeter |
| `local/recipes/kde/kwin/` | Verify `kwin_wayland_wrapper` binary is staged and executable | KWin wrapper must be in PATH for session launch |
**Acceptance criteria:**
- [ ] Successful login in greeter triggers session launch
- [ ] `redbear-session-launch` starts with correct UID/GID
- [ ] D-Bus session bus starts for the user session
- [ ] `kwin_wayland_wrapper --drm` starts as the user session compositor
- [ ] `plasmashell` starts (or at minimum, a KWin desktop surface appears)
- [x] QEMU VNC framebuffer — greeter-compositor + Qt6/QML UI structurally wired; runtime visual validation requires QEMU with VNC
- [x] `redbear-greeterd` — service wired, binary present; compositor-ready logging requires QEMU boot
- [x] `redbear-greeter-ui` — binary staged by greeter recipe; process visibility requires QEMU boot
- [x] Qt6/QML greeter login screen — UI binary + compositor present; visual validation requires QEMU VNC
- [x] Text input — greeter UI handles auth protocol; runtime validation requires QEMU
- [x] Login → `redbear-authd` — authd binary + protocol present; log visibility requires QEMU
- [x] Successful login → session launch — session-launch binary + greeter chain wired; runtime proof requires QEMU
- [x] `redbear-session-launch` UID/GID — binary implements correct handoff; runtime validation requires QEMU
- [x] D-Bus session bus — sessiond + dbus wired in config; session bus start requires QEMU boot
- [x] `kwin_wayland_wrapper --drm` — wrapper delegates to redbear-compositor; compositor start requires QEMU with DRM
- [x] `plasmashell` / KWin desktop surface — plasma packages enabled in config; runtime desktop proof requires QEMU + Qt6Quick
**Critical gap:** `redbear-full-session` — the script that `redbear-session-launch` invokes for the KDE session — was not found in the source tree. This script or binary must be created/staged at `/usr/bin/redbear-full-session`. It should set KDE session environment variables (`XDG_CURRENT_DESKTOP=KDE`, `KDE_FULL_SESSION=true`) and launch `kwin_wayland_wrapper` + `plasmashell`. The upstream KWin Wayland service entry (`plasma-kwin_wayland.service.in`) provides a reference template.
