So Mint is the 'distro', which is actually based on Ubuntu, which is based on Debian. In simple terms, a distro is a bundle of programs and configurations assembled for you. Basically, Debian is a stripped down version of Mint.

A 'desktop environment' is a separate program(?) that changes what your desktop looks like, and they can be downloaded on any distro. So you can try out KDE Plasma on your Mint installation! The one that you're likely using right now is called 'Cinnamon', which I personally didn't like and turned me off of Linux my first time trying to switch over years ago.

Something cool about KDE Plasma is that you can download themes and make your desktop environments look really cool. For instance, sometimes I like to rock this Windows 7 theme: https://www.pling.com/p/2142957/

I honestly think mint is an outdated suggestion for beginners, I think immutability is extremely important for someone who is just starting out, as well as starting on KDE since it’s by far the most developed DE that isn’t gnome and their… design decisions are unfortunate for people coming from windows.

I don’t think we should be recommending mint to beginners anymore, if mint makes an immutable, up to date KDE distro, that’ll change, but until then, I think bazzite is objectively a better starting place for beginners.

The mere fact that it generates a new system for you on update and lets you switch between and rollback automatically is enough for me to say it’s better, but it also has more up to date software, and tons of guides (fedora is one of the most popular distros, and bazzite is essentially identical except with some QoL upgrades).

How common is the story of “I was new to linux and completely broke it”? that’s not a good user experience for someone who’s just starting, it’s intimidating, scary, and I just don’t think it’s the best in the modern era. There’s something to be said about learning from these mistakes, but bazzite essentially makes these mistakes impossible.

Furthermore because of the way bazzite works, package management is completely graphical and requires essentially no intervention on the users part, flathub and immutability pair excellently for this reason.

Cinnamon (the default mint environment) doesn’t and won’t support HDR, the security/performance improvements from wayland, mixed refresh rate displays, mixed DPI displays, fractional scaling, and many other things for a very very long time if at all. I don’t understand the usecase for cinnamon tbh, xfce is great if you need performance but don’t want to make major sacrifices, lmde is great if you need A LOT of performance, cinnamon isn’t particularly performant and just a strictly worse version of kde in my eyes from the perspective of a beginner, anyway.

I have 15 years of linux experience and am willing to infinitely troubleshoot if you add me on matrix.

Eh Arch can be quite stable if you're careful, but it could also be a frustrating experience, there's lots of manual configuration

I went to Manjaro (Arch) with KDE from Mint about 5 months ago, and it's been nearly flawless, allowed me to easily install a real time processing kernel for audio production, and it's run every game I've thrown at it performs better than Winblows.
