Everyone hypes Mint but if you’re working with newish hardware you might have a bad time due to the drivers taking a while to mature and filter down through all the distros. If her rig is a couple years old it should work just fine though. I would also suggest trying out Kubuntu, Pop!_OS, PikaOS, and Zorin if that is the case.

If she is on brand new hardware then something Arch based is the way to go IMO. CachyOS, Garuda, and EndeavorOS are all Arch based distros that make setup easy and they’ve all worked great for me out of the box. Honestly if you have snapshots configured with timeshift or something being on a rolling distro isn’t as scary as it’s made out to be. Fedora is an option too as they get updates every 6 months, but there is a little extra setup to do after install like media codecs and proprietary drivers etc.

Cachyos was my personal pick and it’s working perfect for me so far.

I have issues with Ubuntu based distros and my Nvidia card, Arch based seems to work great though. Don’t ask me why lol, I’m just getting back into Linux and still learning but that was my experience.

You can try a distro that includes the driver on installation to avoid a some of the headache. I have a 4060ti and I’m using Cachyos with zero issues.
