ok forgot to mention, unless you know how to use commands its safer to then issue
reboot
your new xorg file has been saved to your special folder so you can "persist" after reboot.
My script does not care if you have come from vesa (and no xorg) or nvidia or vesa with xorg.
That is because I have your new TCZs in the special folder and your -/optional folder
---but they have new names so no conflict between old and new nvidias
for persistence list just add nv.tcz (as dependencies are taken care of)
and if you have existing nvida-glx xorg.conf, keep it ---Otherwise
copy in your new xorg from special folder and save file to backup filetool.lst
code is...TRY AT OWN RISK
