Module display 

In-container real-display takeover supervision.

Display providers are process-level adapters behind /ops/display. KasmVNC is the current provider and is kept as an external GPL process: afhttp only starts Xvnc, waits for its X display + localhost web listener, and reverse-proxies the web client from the authenticated host listener.

Structs

DisplayHandle

Running KasmVNC display. Cloning the surrounding Arc keeps the process alive until the listener state is dropped.

DisplayProxyState

Minimal state used by the listener reverse proxy. Tests can construct this without spawning KasmVNC; production keeps the process alive via _handle.

Constants

DISPLAY_HEIGHT

DISPLAY_WIDTH

Virtual framebuffer geometry for the takeover display. No window manager runs on the X display, so the headful browser window is pinned to this size (see AppState::launch) to fill the framebuffer.

Functions

launch_display_provider

Launch a display provider and return the runtime state used by /ops/display.

launch_kasmvnc_provider

Launch KasmVNC’s Xvnc and wait until both the X display socket and the embedded web client are reachable on localhost.
