Hmm. I know with Ubuntu they have a driver pack that you can specify to install vs getting the one from nvidia. Fedora has something similar and I hope this may help you get proper drivers:
https://discussion.fedoraproject.org/t/installing-nvidia-drivers/117246/7
In Ubuntu there was a command line client that you run to validate the display driver (nvidia-smi?) it spits out details of the installed card. When that is working everything else should. If I also recall, there was a nvidia graphics docker container that you can stand up as well
Anyway let’s see how you do with getting the right drivers up and running for you.
Cabernet with daddylive plugin, this can emulate hdhomerun on your network, add this to plex/Jellyfin for live tv. https://thedaddy/ . to Check the list and see if these 24/7 channel streams work for you.
I integrated these into plex and are able to watch live tv the way I want. Cabernet is a docker container on my network, ensure you set the ip address to the server vs the docker IP, in the Cabernet web ui settings.
If you want to just watch streams off that site, I recommend using brave browser, turn on all the ad block capability and set it to strict and even import the hagezi multi pro blocklist in brave. The amount of pop ups on that site is horrible. But brave smooths them out and streams are fairly reliable. Plenty of sports.
