ov eval vnc passwd my-image --generate # set up VeNCrypt/TLS auth
NVIDIA Headless: Fixed via Pixman + DPMS Workaround
VNC screenshots work correctly on NVIDIA headless when used via sway-desktop-vnc (the standard VNC composition). Two fixes make this work:
-
Pixman renderer —
sway-desktop-vncsetsWLR_RENDERER=pixmanin its layer env, forcing software rendering. Thesway-wrapperskips GPU auto-detection whenWLR_RENDERERis pre-set. -
DPMS workaround — wayvnc 0.9.1 gates screen capture on
zwlr_output_power_v1mode events, but sway's headless backend never emits them. Thewayvnc-wrapperperforms a minimal VNC handshake to trigger wayvnc to bind the power manager, thenswaymsg "output HEADLESS-1 power on"forces the missing event. Fixed in wayvnc git main (post-0.9.1) — remove workaround when Fedora ships the fix.
For images NOT using sway-desktop-vnc (custom sway + wayvnc setups), ov eval wl screenshot (grim) remains a reliable fallback.
Startup Timing
The wayvnc-wrapper uses a two-phase wait:
- Wait for Wayland display socket (
wayland-0) - Wait for sway IPC socket (
sway-ipc.*.sock) + 2s delay
This ensures sway has set the output resolution (default 1920x1080) before wayvnc connects.

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).
