Linux

My big question would be why are you starting with a dual boot? I would recommend trying each one with a liveUSB or in a virtual machine and simply do a single boot with the one you like better. There’s likely little need for you to actually maintain two distros unless you have a very niche use case that one distro can’t solve.

My advice would be to just relax and realize that the underlying OS is 90% the same regardless of what distro you choose. All the discussion you see on different distros, package managers, snaps, wayland, etc. are all the other 10%. It really doesn’t matter what distro you start on as long as it’s a general purpose distro (both of the ones in your OP are): once you learn the first 90% of linux, you’ll develop your own tastes, and then you’ll be able to decide on the remaining 10%.

Keep notes on what you do including outcomes. You can always reinstall, skip all of the extra crap you didn't need to mess around with and have a good clean system without having to back track.

OpenSUSE Tumbleweed is an awesome distro with up to date packages. KDE is also a great choice, especially with Plasma 6.0 around the corner.

I wouldn't worry too much about Nvidia drivers, just follow OpenSUSE's guide [1]. The remaining issues of Nvidia with KDE Wayland are getting fixed over the coming months.

Edit: OpenSUSE can't ship some codecs by default for legal reasons (like RedHat, Fedora), but makes it simple to enable them (optionally through graphical YaST) [2].

I'm also a beginner and I noticed that debian let me install a lot of possible desktops. So I installed all of them, and I can switch on the password screen which one to open. I'm trying some stuff this way.

Hello OP, warm welcome to the schizophrenic community that is linux! I’m running this exact same setup as you intend to.

Couple of points I’d add:

1. Nvidia and linux is a shit show. You either use the gimped mesa drivers (not so good), or the closed source drivers (even worse), especially on Wayland. If you still want to try it out, I suggest you stick with X11. I was using a 3080Ti and gave up trying to get it to work on Wayland+KDE Plasma v5 without screen glitches and bought a 7900XTX instead. AMD works out of the box without further configuration. I’ve had nothing but issues with Nvidia. For the GPU neckbeards that are going to achytually me, please don’t, I have no skin in this game as I have a bunch of cards from both.

2. I am not a pro nor expert in the foundations of linux, but I more or less know my way around its fundamentals (enough not to get into too much trouble), so I would actually suggest not getting into a rolling-releasing distro like Tunbleweed until you are super comfortable with a little hands-on and figuring shit out. Pop!_OS might be a better bet for your use case for now because it comes bundled with Nvidia drivers, but it uses a GNOME derivative (cosmic DE) so you don’t actually get the KDE experience.

Having said these, I absolutely adore Tumbleweed and KDE, I’ve been half daily-driving it but the gaming experience is not the absolute best (be prepared to experience weird glitches and crashes). If a flawless gaming experience is non-negotiable to you, stick with Windows. But if you’re ready to explore the quirky wonders of linux, the beauty of it all is the experience and the real reward is the friends you make along the way.

If you're going to be using a DE and mostly do stuff through the GUI instead of terminal/command-line then make sure you can go admin mode (Root/Sudo).

Besides small annoyances I had with KDE Plasma 5's UX the main reason I didn't like it was that often enough I would have to use admin privileges but I couldn't do it through the GUI File Manager (Dolphin) so I frequently had to use the terminal.

It should be possible to have admin privileges in Dolphin but I was a noob and didn't know how (and still don't even now).

If you end up facing that issue then either be a bit smarter than me and look up how to do that or use Nemo, another file manager, which is more or less the same thing as Dolphin except when I ended up using it on Linux Mint a while back it let me use it as Root as a feature out of the box.

And for the record I don't like Linux Mint, apt package manager sucks (package managers are basically app stores where you get all your stuff), but at least it was super easy to install and Nemo was a good file manager.

If you don't mind tinkering and have a secondary device with an internet connection in case you break something then I would recommend Arch Linux. Or you could try it in a Virtual Machine I guess.

Pacman (Arch's package manager) is a hundred times better than Apt, and then there's the AUR on top.

Also while I've never used it I hear a lot of good things about EndeavorOS, Arch Linux but supposedly easier

After contemplating for 3-4 years about switching my main rig to Linux, I did it on Friday just gone.

Note for the below, I have a full AMD system.

• I went with Garuda Dragonized distro as it is gaming focused and has all the game related stuff included.
• took me less than 30mins going from gaming on Win11 to Linux, but I did the research before.
• there are a few tweaks if you use Steam but you have Lutris to help you.
• of the 35 ish games installed, all of them work without issues, but they need updating once you enable compatibility to Proton.
• the default theme is too flashy but you can select to bring it down a few notches

Technical

• if you have secondary SSD or HDD, dedicated to games or files like I did, it is advisable to have them backed up to an external drive as you will need to re-partition them from NTFS to use them properly in Linux
• with Garuda Dragonized Gaming, all drivers are installed but follow the Wizard at the beginning and check all that apply to you. It will save you time.

Good luck and looking forward to having you on Linux!

OpenSUSE + KDE is a really solid choice, I'd say.

The most important Linux advice I have is this: Linux isn't Windows. Don't expect things to works the same.
Don't try too hard to re-configure things that don't match the way things are on Windows. If there isn't an easy way to get a certain behavior, there's probably a reason for it.

I used to run Tumbleweed with KDE on my Nvidia system. I found the rolling release structure of Tumbleweed to cause extra work for me, because kernel updates came frequently and occasionally broke the Nvidia drivers. As a workaround, I ended up pinning my kernel to an old version.

Nvidia drivers have been at least a little troublesome on every distro I've used, particularly with the additional CUDA libraries.

One nice thing about Suse is that it uses BTRFS by default, and you can use snapper to revert your whole system if something goes wrong. So if Nvidia shits the the bed after an update, it's easy to roll back. Most distros default to ext4 and do not have snapshot support by default, which feels like living in the stone age to me after using Suse and BTRFS.

Of course you CAN set up BTRFS and snapshots in any distro, but that's a lot to ask for a beginner with Linux. I strongly recommend choosing a distro that does that for you, like Suse.

If you're planning on gaming, and you have an NVIDIA card, then I would like to recommend Bazzite. I've been using it for months, and I'm very happy with it. Have it installed to my Steam Deck as well as my PC.

If you encounter problems you can't find information on, do Ubuntu LTS next and use askununtu.com, help.ubuntu.com and wiki.ubuntu.com. The existing documentation and the largest community is what makes this the easiest option. Once you gain XP for a couple of years that XP is transferrable to Debian.

The hardest part is when you need to use tools from windows, or to develop a program for that system. Also, many things require good amount of configuration, and with that, expertise at what you doing. I'm currently struggling with solving bug as to why VSCodium will not debug in external terminal.
