xdg-portal-kde -- KDE XDG Desktop Portal backend
Layer Properties
| Property | Value |
|----------|-------|
| Dependencies | dbus, kwin, pipewire |
| Install files | layer.yml, tasks:, portals.conf |
Environment Variables
| Variable | Value |
|----------|-------|
| XDG_CURRENT_DESKTOP | KDE |
Packages
xdg-desktop-portal(RPM) -- Portal daemonxdg-desktop-portal-kde(RPM) -- KDE portal backend (ScreenCast, RemoteDesktop, FileChooser)
Portal Configuration
portals.conf (installed to ~/.config/xdg-desktop-portal/portals.conf):
[preferred]
default=kde
org.freedesktop.impl.portal.ScreenCast=kde
org.freedesktop.impl.portal.RemoteDesktop=kde
Routes ScreenCast and RemoteDesktop requests to the KDE backend, which supports both PipeWire screen capture and libei input injection.
Portal Capabilities
The KDE portal backend provides:
- ScreenCast -- PipeWire-based screen capture via
zkde_screencast_unstable_v1 - RemoteDesktop -- Input injection via libei/EIS (
ConnectToEISmethod) - FileChooser, Screenshot, Notification, GlobalShortcuts, InputCapture, Clipboard
Known Limitation
The zkde_screencast_unstable_v1 Wayland protocol is not exposed by KWin's --virtual backend (as of KDE 6.6.3). Portal ScreenCast/RemoteDesktop sessions fail with response code 2 in headless mode.

Use when authoring or modifying a charly PLUGIN — a candy with a `plugin:` block that contributes Providers (verbs/kinds/deploy-targets/steps/builders/commands), its own CUE schema, builtin (compiled-in) or external (out-of-tree git repo). Covers the unified Provider model, the per-plugin CUE-schema contract (single source → Go params for dev + schema-over-Describe RPC for runtime), the SDK, and the loader.

The CUE data-validation / configuration CLI (cue), pinned to v0.16.1. Use when working with the cue candy, installing the cue binary into a box or onto a target:local dev host, or running the offline schema-vendoring pipeline that feeds charly's egress validation.

CUE EGRESS validation — validating (and, where it adds value, generating) the config files charly WRITES to a system BEFORE the bytes hit disk. MUST be invoked before working on charly/egress.go, the vendored schemas under candy/plugin-egress/egress-schemas/vendor/, the ValidateEgress / registerVendoredEgressKind path, the offline `task cue:vendor` pipeline, or adding an egress schema for any written artifact (cloud-init, k8s manifests, traefik routes, runtime config, install ledger, systemd/quadlet units, ssh_config, libvirt XML).

Kubernetes cluster-probe declarative check verb — the `kube:` check verb (nodes, pods, ingress, storage class, addon health, apply/delete, and arbitrary resource GETs) served out-of-process by the candy/plugin-kube plugin (vendored client-go; no external kubectl required).
