If your process has a top-level X11 window, even if it is not visible, you can close that window from any process. You need just the handle of that window. I added the Window.Handle property to gb.sdl2, it will be committed when Sourceforge servers come back. Meanwhile, you can use Desktop.FindWindow() in 'gb.desktop' to search for a window with a specific title and get its handle. Then you call the Desktop.Windows.FromHandle(id).Close() method to close it.
