About NVIDIA: yeah, Nvidia on Linux is a big, big mess. Things are improving but it’s still a pain in the ass sometimes. Maybe some of your issues could be solved by changing to another Desktop Enviroment.

About Bluetooth: I don’t know how recent your hardware is, but maybe changing to a newer kernel (preferably a more up to date Distro, like Fedora) would solve it.

About Compatibility: I don’t know what controllers you are using. I personally had issues with Xbox Wireless Controller drivers, and after some searching I easily fixed it with xpadneo, maybe that could help.

Mint is usually a great distro for beginners, BUT it sometimes sacrifices shiny new updates for stability (which is a good feature of Mint), that’s why I recommend you to try Fedora. Good luck with your Linux adventure 😃
