Way back when I was playing the role of deb maintainer and contributing to a distro we went this route. Nvidia Proprietary drivers caused more than a few headaches. Nvidia wasn’t the best at considering deb integration or playing well with others and small differences in individual systems caused complex errors that were often extremely hard to diagnose (example: a needle in a haystack config difference threw Nvidia off and were hard to find, Nvidia not too helpful messaging-wise, etc.). The distro’s I worked on Sid based and that contributed but as an end user, there is nothing less acceptable than booting into my fresh install and getting a black screen. This was several years ago, perhaps Ubuntu and Nvidia co-operate better than before, perhaps my knowledge is obsolete but I did want to explain my no vote.
As a distro, you do have to find a happy medium between new install ease and usability. You also need to keep focused on who you are. You have a really super distro here that seems to be focused on providing a lite-weight, beautiful, rock solid distro that doesn’t have a large footprint. From there users can configure what they do or don’t want. That is my sense or your core mission, I could be wrong.
For me personally there are some things I install every time I do a fresh install (qBittorent, Geany, Nvidia drivers, gMusic Browser, etc) but I wouldn’t choose Budgie for those items, I select a distro that I can download quickly, get up quickly and configure to my tastes with as little effort as possible and will stay solid after the install. Budgie does that magnificently.
I don’t see how adding the Nvidia Drivers fits with your mission or niche. It’s an easy trap to fall into, to try to be more and appeal to more people, distros expand infinitely. Sometimes less is more.
Apologies for the long post, love what you have done here and with or without Nvidia drivers can’t see me leaving.
