Ok, I'm using that and GDK_WINDOW_XDISPLAY for use in a lib that is
expecting either a X11 Widget or a X11 Display and a X11 Window,
but apparently the Display and Window info I get is not usable:
I get:
Error: Couldn't find per display information
If I create a X11 Widget within the application, take its Window und use
its Display and Window everything works fine.

Any help?
