Everything else? Including Wayland, fractional scaling on non-Qt apps, sleep, hibernate and HW video decode?
Yeah, I know if you have very common HW and restricted use cases, like track-point, USB mouse, display without fractional scaling, not using sleep/hibernate etc, then everything just works but those also "just worked" on Linux for the past 20 years.
I need linux to work on modern HW with modern quality of life features enabled that all the other OSs have out of the box, not to have to go back in time on how we used PCs 20 years ago just so Linux can feel at home.
If stuff like hibernate or mixed-DPI fractional scaling is still a foreign concept to it, then it's not year of the linux desktop for me.
As always, everything just works on Linux with the caveats that as long as you stay on the very fixed beaten path, never stray from it, only use X,Y,Z and avoid A,B,C, then everything just works, sure, but I'm not a college student anymore and my time is too valuable to tinker and find that new specific Linux path where everything just works in order to get the same desktop usability that Windows has out of the box with zero time investment.
It is what it is.
I use a ThinkPad, so I prefer the TrackPoint and rarely use the TrackPad, but everything else works excellently, especially with KDE.
