Exactly. When you su root, $DISPLAY is not set, so you would have
to set it first, maybe like this:


	#!/bin/sh
	su root -c "\
		export DISPLAY=:0.0; \
		xterm -geometry 80x25 -title 'App 1' -e 'app1' &
		xterm -geometry 80x25 -title 'App 2' -e 'app2' \
	"

You could do this:

	xterm -geometry 80x25 -title 'App 1' -e 'app1 ; csh' &

which would start your prefered dialog shell when "app1" has
finished. The dialog shell would run even if "app" fails (thatÄs
why I suggest using ; instead of &&).

This sould be able to be achieved using the example above.
