Off-topic: F*** slashdot and this "anonymous posting has been turned off" stuff. I wouldn't even mind logging it if I had the option to post what I had typed after doing so. Now I'm forced to recreate and re-edit what was otherwise a magnificent piece, and I'm sure that I'm now too irritated by the very notion to be as calm and gentle as I was a moment ago.
But I digress...
It seems like you've chosen the wrong distro. In Ubuntu (or Mint, or the incredibly numerous Ubuntu derivatives), installing proprietary drivers is as easy as doing a desktop search for "additional drivers" and choosing which one you want to use. Then DKMS handles the *module* (different from whole kernel) compilation for you.
Having said that, I and my wife use Nvidia's proprietary drivers on our gaming and multimedia consoles, and they work great (games like No Man's Sky work better under Steam's "Proton", which is a Steam customized version of "WINE", than they do on Windows 10, admittedly largely due to Linux's endless customizability compared to Windows' limited version of the same -- you can only turn off so much on Windows, in Linux, you can turn off the whole dang thing if you're so inclined), but Nouveau drivers (or rather, open source drivers in general) are the only driver capable of teaming multiple cards from different manufacturers together. My primary workstation, which I use mostly for audio design and engineering, needs as much pixel real estate as possible to emulate the look and feel of racks of hardware, effects plugins, and patchbays, and runs an old onboard intel card alongside an (also old) nvidia card on the PCI bus. Both have dual heads attached (1920x1080 primary and 1280x1024 on the nvidia, 1280x720 projector and 1280x1024 on the intel), and I can run 30 FPS on all at the same time with no issues. Can't do the same AT ALL on Windows, much less with everything pegged. And for everyone guffawing at the framerate, bear in mind that when I need high FPS I use another machine, and 30 FPS is more than everyone here is used to seeing on the biggest screens, and I can assure you, when you're just using pixels for knobs to turn, that's plenty faster than our eyes or fingers.
And for my final point, I'll just mention that the people at Disney (Marvel, Pixar, etc.), Universal, Sony, and WB, are definitely not using Windows or macOS. They're using custom Linux workstations with software built by engineers in house like everyone else in tech. Only the very lowest rung of "professionals" are using anything but Linux, and most of even them are on Macs. Professionals in the multimedia content creation industry do not use windows. People who use the OS that came with their inexpensive hardware are the only ones who do. Good for them and good for you, if you or others feel like it's a fair tradeoff to sacrifice performance, bandwidth, and screen real estate in the form of black box services, telemetry, and ads, for a computer that works like a toaster with little to no user input as regards setup or maintenance: enjoy your toast!
