Just wanted to share for the 10 people like me who has with an Nvidia + dual screen setup on ArchLinux (btw) with KDE Plasma desktop that since the new plasma 6 update I can finally use the Wayland session option!
The wayland should work has been around for the last 5 years and 5 years ago it was not even close, then 1 or 2 years ago it started not crashing but multi-screen was not OK (I tried all the kernel and driver parameters).
Now for me and my 5+ years-old setup (probably a lot of legacy plasma settings in my .config) it was finally seamless.
From previous tries I already knew that the desktop feels WAY smoother (true 60 fps everywhere, specially for the video players in web browser).
Feels great so far, discord screen-sharing is not there but can be done from Firefox if needed so OK for me.
I hope this post will be informative for some like me who tried several time over the years and didn't had much hope.
PS : the cursor has a weirdly strong outline (too shiny to my taste) feels like unintended but not a big problem. I spent 30 mins in the options but couldn't find anything about that.
I tried Plasma 6 + Wayland on Arch btw earlier today, ran into the first issues in like 3 minutes after installation and switched back to Xorg for good. Wayland never worked for me. Yes it's much more smooth and has nice features but it just never works that well on my machines. Btw for all the Wayland bodyguards, it was on Intel integrated graphics, not on NVidia or anything like that
Damned, this is so frustrating when you cannot switch yet. Not like Wayland is perfect anyway but I felt the same with pipewire where the new system as some needed improvement but the switch is harsh.
Never had issues with Pipewire smh. I didn't even notice the transition
