[racket] fullscreen without windowmanager?

Hi all!

I want to make a follscreen window on Xorg without windowmanager. This code 
works, when a windowmanager is running, but it fails without, i.e. the window 
is 300x300.

#lang racket/gui
(define frame 
  (new frame% 
     [label "test"]
     [width  300]
     [height 300]
     [style 
(list'no-resize-border 'no-caption 'no-system-menu 'hide-menu-bar)]))
(send frame show #t)

Even when I add a (send frame maximize #t), it does not work. 

Any idea how to get this working?
