su doesn't preserve the DISPLAY environment variable, so you can use one
of the following:

    sudo bash -c "xterm & xterm &"

    su root -c "DISPLAY=$DISPLAY ; export DISPLAY ; xterm & xterm &"

I'm not sure.  It may be possible to play shell-specific tricks that
cause `app1' to be executed as part of the shell's startup scripts.
