This surely is not my area of expertice, but the patch looks fine. I am 
wondering what the separate utility is used for. Wouldn't it be better 
to put that code into the [XGServer initForDisplay:screen:] method and 
execute it, when the test there fails? The problem is of course that 
than back would need to link with all the Xmu stuff, so we would need 
configuration stuff to detect, if this is present.

Actuall Xmu looks pretty usefull for other things as well. I will have a 
deeper look at the functions there.
