Exactly that's what has been my suggestion (without having been
mentioned): both "xwd" and "import" support a -display option.
In case the root window (equals the whole screen) is captured,
no further interaction is required (at least in case of xwd).
This makes it easy to obtain screenshots non-interactively
(e. g. time-triggered) from "outside" the X session.
