Hi,

Check whether you have removed the file "/etc/X11/XF86Config-4" or not . If my guess is right then the file is still lying in your remaster and it is using that file with setting of computer on which you remastered and is not creating a new one.

To solve the problem, if the file is there, remove the file XF86Config-4 from remaster source, compress and make iso again.

Post the results.......
