I did not know this. Combining with another tip the code now has
become:
    (when (display-graphic-p)
      (set-scroll-bar-mode 'right)
      (tool-bar-mode -1))

I work with screen and emacs on this system. The problem is that
sometimes the connection goes away. And if this happens my emacs will
hang. With screen I just can continue where I left of after the
connection is restored.
