... but when I change the 'x' and 'y' values all the graphics (board and pieces) disappear.
Well, what have you entered for x and y?
The graphics disappears (i.e. is reset to the default internal layout), if anything in the layout file is wrong, e.g. if you enter unknown commands or illegal values.
So post the line(s) where you've changed the x and y values (or anything else).
