I don't recommend Manjaro. The devs have repeatedly made serious errors, and there are no benefits to this distro over its parent, Arch. Out of the base Arch install you'll boot with the nouveau driver, which should work flawlessly, but comes with severe performance limitations. To install the proprietary driver, you'd run sudo pacman -S nvidia, and add MODULES=(nvidia nvidia_modeset nvidia_uvm nvidia_drm) to your /etc/mkiniticpio.conf (or rather, add the nvidia modules to the list of modules already present), and run sudo mkinitcpio -P. No further configuration should be necessary, just reboot the computer. When new kernel or nvidia updates are installed, pacman should automatically run mkinitcpio, so you only need to do this separately the first time.
I've gotten Wayland and KDE to work reasonably well with the Nvidia drivers lately, but that's with a 4090. 30-series would probably work fine as well. Earlier than that is where you still have serious issues, and unfortunately they're unlikely to be fixed, even the open-source drivers they're working on are only intended for 30-series and up. If you've got something older than that you'll either need to upgrade your card, or stick with X11.
I have a second M2 ssd being delivered this week, I'll give arch a try but i fear i won't be able to get it to work because i'm catastrophically heterosexual and cis gender and fueled by racism, misogyny, islamophobia, antisemitism, homophobia, and transphobia.
Edit (to prevent double post):
Not sure how much time you spent in each distro, but you may need to enable the proprietary drivers in your grub config. Dealing with Nvidia has generally been one of the more frustrating aspects of Linux for me lately, but I'm also using a poorly support GPU that has led its own complications. Hopefully it doesn't give you too many issues going forwards, I'm hoping Nvidia makes Linux a higher priority in the future.
I hadn't used linux in like 8-10 years but when i bought a steam deck and seen how well it was working in desktop mode and how well it ran games on the steamdeck i decided to give it a shot again so i'm definitely not a super user but i am a tech literate person who understands things like primative data types vs class objects, compilers, libraries, rendererers, neural networks, etc.
So i'm by no means a person who is an expert in specifically linux but i'm also not a fisher price level computer user.
My goal with this install setup was to have a windows 10 install (for break glass in case of emergencies needing to use windows for something i absolutely have no choice in but to run in windows, [or don't have time to figure it out in linux]), have one of the baby bitch distros up and running (like ubuntu or mint) for basic video playing/web browsing, gaming, everyday use shit that i can depend on while i make a third partition for one of the more expertise requiring distros that i expect to fuck up and have to start over and reformat and install repeatedly while i learn how not to suck.
Ubuntu, mint failed me then i tried manjewro and the nividia drivers just worked and so did everything else except the app store like "add/remove software" gui tool. but every time it fails to install something, it says the library name and i just" sudo pacman -S <whatever the name the error had where it said it couldn't find it>" in terminal and it finds it just fine.
thats the only issue i've had so far in mandingo distro and i figured its okay because it'd probably better for me to use the terminal a little more anyway to get use to it.
