Linux Mint Xfce Edition should be right up your alley.
yala
Technically, if you would have been on Fedora Atomic, you could have just rebased to the Kinoite branch. Perhaps even created a new user so your home folder doesn't get populated by unwanted stuff. And, afterwards, you could rebase back to whatever your original branch was.
Furthermore, downloading any distro that defaults to KDE and offers a live environment should be able to offer you a KDE experience within the live environment as well.
Or, perhaps, consider another distro.
I’m still on the hunt for a distro where everything I need is easy to install. I don’t think any exist, primarily because GPU drivers suuuuuuuck, especially when you need CUDA or ROCm to work.
Have you looked at the opinionated images by uBlue, i.e. Aurora, Bazzite and Bluefin? FWIW, e.g. for Bazzite, AMD's ROCM OpenCL/HIP run-times are fully supported OOTB and there's a workaround for CUDA. It does a lot of good stuff in general. Heck, I'd argue they're one of the most handsfree and easy experiences you may find on Linux.
I expected this to be more feasible on the Intel models for whatever reason.
Historically, in the past few years, for devices that support coreboot, we've had more Intel models than AMD models. So perhaps that's were your hunch stems from.
We actually already have an experimental coreboot port on the FW 13 AMD.
And, from my understanding, Framework has sent over a device to make this possible.
However, I don't know if it will ever get official support. Though, surely, I hope it will.
Support for coreboot can't come soon enough. My fingers are already tingling in excitement for that day.
Unfortunately, I can't take this seriously as 1% lows and additional variance due to difference in DE haven't been accounted for.
Furthermore, you bet that Tuxedo OS has done a splendid job at optimizing performance on a device that's sold by Tuxedo. Therefore, I wonder if it's even a fair comparison to begin with.
OS is xubuntu 24.04
Ubuntu defaults to ufw. That, by itself, justifies the use of ufw in your case.
IIUC, Q4OS only shares its source code on request. Furthermore, the Windows installer is a fork (or somewhat based on) WubiUEFI.
Q4OS still has a .exe installer though.
TIL. This is pretty cool. I wonder how much effort it would cost to make this a viable option for most of the popular distros.
Until its drivers are completely open source, Nvidia will continue to cause trouble every once in a while.
Therefore, if you liked Sway, then don't leave it expecting to be a lot better elsewhere.
However, Hyprland's community is pretty big and I can only be positive regarding the pace of its development. Therefore, if anything, Hyprland might be able to offer a solution. But, don't forget what I said earlier*.
