Oh, one thing, I missed this, found it when checking: the driver in:

NV_VERSIONS='387.22:340.104:304.137:173.14.39:96.43.23:71.86.15'

first position is always current stable primary, not lt stable primary. I've corrected that. The lt drivers are always, unless they coincide with the current stable primary, which happens often, only installable by -o option, since the assumption is most users of sgfxi want the latest driver as the default selection for their card type, the lt stuff is probably generally packaged by their distros. Well, who knows, lol, distros don't do a great job keeping up in most cases.
