Set up and operate a persistent Ubuntu development desktop with VS Code and Codex through npa tools desktop, including readable Retina rendering and authenticated public HTTPS access.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Development desktop Use `npa tools desktop` for an operator's remote development environment. Implementation belongs in `npa/src/npa/tools/desktop`, independently of Workbench. 1. Inventory the exact existing VM and its SSH access. Preserve its checkout, running applications, credentials, and unrelated services. The current installer supports Ubuntu AMD64 and requires passwordless sudo. 2. Run `npa tools desktop setup --ssh-host <alias> --dry-run --json`, then the same command without `--dry-run`. This installs XFCE, TigerVNC, the pinned noVNC viewer, full VS Code, and the Codex extension. Reuse existing VNC and keyring passwords. The desktop stays on loopback unless public access is explicitly requested. 3. Open with `npa tools desktop open --ssh-host <alias>`. Prefer one active viewer; old noVNC tabs can resize the shared desktop using CSS pixels and make Retina fonts look enormous. The viewer's **More space** control changes workspace scale while retaining lossless rendering and device-pixel density. `display --dpi 192` suits a Retina display; use 96 for standard density. …

How to install
mdr add nebius/nebius-physical-ai/development-desktop@sha256:359594660f8f3abcThe line at the top of this page pins the label git:20260923.f689ed1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
