I'm trying to create a local service which captures status screenshots of a set of monitoring system windows about once a minute.

x2go seemed like it was working great to decouple the service from a physical desktop, until I suspended the connection, at which point the screenshots get wonky (mostly just grey with a little strip of actual window contents along one border, or just all grey, or ...). It works fine when x2go is iconified, just not when it's disconnected.

Is this a known problem/feature? I imagined Xclients wouldn't be impacted by a session being suspended or connected?

thanks. -matt
