As I said, I don't know how these things works but It looks to me as follows:

This code is responsible, that the mainwindow is placed where needed depending 
on the xinerama settings (from upper-left of the desktop):
mythdialog.cpp:56:
	#ifndef QWS
	    GetMythTVGeometry(qt_xdisplay(), qt_xscreen(), &x, &y, &w, &h);
	#endif
	
	    int xoff = gContext->GetNumSetting("GuiOffsetX", 0);
	    int yoff = gContext->GetNumSetting("GuiOffsetY", 0);
	
	    x += xoff;
	    y += yoff;
	
	    setGeometry(x, y, screenwidth, screenheight);

But the following (from the patch) does not position the main window, but the 
stuff inside the mainwindow, whereas the first two parameters of setGeometry
() are the offset from the upper left corner of the mainwindow (not the 
desktop!)
	     if (setsize)
	     {
	-        setGeometry(x, y, screenwidth, screenheight);
	+        setGeometry(0, 0, screenwidth, screenheight);

So if using x and y here, too, causes the interior to be moved for another 
xinerama offset out of the visible area and makes it unusable.


take care, have fun
