You would normally already have both kwin_wayland and kwin_x11 installed, but the default up until now — or at least, in Manjaro, because Arch upstream has already switched to Wayland a long time ago — has been X11. This will now change with the upgrade to Plasma 6.4.
plasma-x11-session is a meta-package. It will take care of configuring your Plasma session for X11, and it will automatically pull in whatever is needed if you don’t have it installed already.
I don’t have sddm.conf in /etc and in /etc/sddm.conf.d/*.
Well, /etc/sddm.conf is strictly speaking not even needed anymore because it is superseded by drop-in files in /etc/sddm.conf.d/. And you will have something in there, normally.
I don’t have the folder /etc/sddm.conf.d/ and installing plasma-x11-session works for me.
If I don’t read this thread before doing the today update maybe I will have problem with login in sddm.
In that case, you will be using the default values as set in /usr/lib/sddm/sddm.conf.d/default.conf.

kwin-wayland = kwayland ?
or do you mean this

DisplayServer=wayland
GreeterEnvironment=QT_WAYLAND_SHELL_INTEGRATION=layer-shell
[Wayland]
CompositorCommand=kwin_wayland --drm --no-lockscreen --no-global-shortcuts --locale1
There is no such package. There is kwin which is wayland only and there is kwin_x11.
plasma-x11-session will pull in kwin_x11 as a dependency.
I installed plasma-x11-session after the update, on reboot it switches to Wayland so you have to select it in the login manager to go back to X11 session.
What I meant is this…

No changes needed: [pkg-upd] 20250613.12fe085f-1 (5c3265ed) · Commits · Packages / core / linux-firmware · GitLab … unless you want to drop some firmwares on your custom builds.
Hello, the latest version of KDE 6.4 is very stable, for my freezing 4x Intel® Core™ i5-5200U CPU @ 2.20 GHz. And in general, the system is more responsive and faster. Keep it up!). By the way on Wayland), I’ve been using it for a few years now, and I like it
Thanks for this! 
I only don’t understand why we should install all the firmwares, especially Nvidia related, even when we only have Intel hardware?
@Wollie the meta package contains the common firmware the original linux-firmware package shipped. Now you can remove the meta package and therefore also remove unwanted firmware. Just try it out and see how minimal your system may need extra firmware packages: https://www.linuxfromscratch.org/blfs/view/12.3/postlfs/firmware.html
If I do so, aren’t the really needed firmwares (which are installed as dependency) becoming orphanes?
