The code in the DirectFB backends that produces the GDK events works 
reasonably well in many cases, while there are cases where some 
functionalities are still unimplemented/broken.
You should file a BR [1] against the directfb component and you may have 
a look at the code in the DirectFB backend [2] and try to produce a 
patch for the unimplemented/broken functionalities.
