@User, as with the 'editor' variable in xschemrc there is also a 'terminal' variable where you specify one installed terminal. Gnome-terminal, xterm, rxvt, and others are all good. My suggestion is always to have at least xterm and/or rxvt. When gnome/gtk comes with an ''upgrade'' and everything on the system suddenly stops working you may need to go for the old simple 'do one thing do it well' terminal. They take very little disk space anyway. If you don't specify a terminal default is to use xterm. May be in the future i can add some heuristics to xschem to search for an available terminal (and editor) and use the first one found on the system, if the user didn't specify any.
