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.
What is available is a x11 server, not more not less, it cannot be used for anything other than x11. If they made X12, it would not work on Nvidia, unless they wrote a new server, which they wouldn’t.
You need to understand that the xorg server everyone use literally does not work on Nvidia, because it uses implicit sync, which is required by the Linux infrastructure. The only thing that works on Nvidia it’s specifically their own proprietary server.
Nvidia does a lot of impressive stuff, but they have neglected the Linux scene for a long time, because it wasn’t convenient, and it shows.
Edit: …what was available… because Nvidia is gradually implementing things the correct way, and Wayland is becoming more and more usable with every driver update. Because, surprise surprise, it does depend on the drivers. Also, both Intel and AMD work perfectly with Wayland.
