Atomic OS’s (especially Fedora based) with Nvidia are going to be a bit of a pain. Did you follow all the instructions found Here ? I personally gave up on silverblue/kinoite after I tried Bazzite. Similar bases, but the Bazzite devs paid special attention to GPU and accessory drivers/implementations that are otherwise much more painful in Fedora Atomics. You can always do a clean rebase then re-run the steps above (only the OSTree section).
Isn’t this almost the inverse argument to the android vs iPhone thing? Like the iPhone being (traditionally) more expensive for the “same technology from 5 years ago”? I don’t really have a horse in this race, I’m a firm believer in use what you like and is easiest/best for you. But I do feel compelled to call this one out a bit.
