nvidia-settings tools saves "stuff" to hidden file:
~/.nvidia-settings-rc

This hidden file can have permissions that are problematic.
Change permissions or run tool as sudo.
(Don't save to xorg.conf file..this tool can make a mess)

You can get these custom settings reloaded with:
/usr/bin/nvidia-settings --load-config-only


You could use a script auto-started by the desktop session login.
