output inxi -F

Try switching to xorg instead of wayland.

CC: (none) => davidwhodgins

Output for:
echo $XDG_SESSION_TYPE

Gives alreaady:
X11

So there is no wayland in use.

Although.......i have a mass load of wayland packages installed.
I had the NVIDIA-card configured through mageia-prime-install.

Sorry, I had just noticed the Xwayland in the inxi output, and didn't look
closely enough.

If it's currently running xorg, try switching to wayland.

I remember that some times for hybrid graphics after kernel and drivers updates is useful run uninstall and install commands

Any suggestion how to realize such switch?

You actually propose to run first:
mageia-prime-uninstall -z

After that:
mageia-prime-install -z

Correct?

To try wayland, it should be an option in the menu (sddm, gdm, etc).

I have the following wayland packages installed, though I usually use xorg
kwayland-5.105.0-2.mga9
kwayland-integration-5.27.5-1.mga9
kwin-wayland-5.27.5-1.mga9
lib64gstwayland1.0_0-1.22.5-1.mga9.tainted
lib64kf5wayland5-5.105.0-2.mga9
lib64qt5waylandclient5-5.15.7-2.mga9
lib64qt5waylandcompositor5-5.15.7-2.mga9
lib64qt6waylandclient6-6.4.1-3.mga9
lib64wayland-client0-1.21.0-1.mga9
lib64wayland-cursor0-1.21.0-1.mga9
lib64wayland-egl1-1.21.0-1.mga9
lib64waylandpp1-1.0.0-1.mga9
lib64wayland-server0-1.21.0-1.mga9
libwayland-client0-1.21.0-1.mga9
libwayland-server0-1.21.0-1.mga9
plasma-workspace-wayland-5.27.5-2.1.mga9
qtwayland5-5.15.7-2.mga9
wayland-tools-1.21.0-1.mga9
x11-server-xwayland-22.1.9-1.1.mga9

Another way to start it is to boot to run level 3 (add " 3" to the kernel
options), login in text mode and run
XDG_SESSION_TYPE=wayland dbus-run-session startplasma-wayland

For gnome, it's
XDG_SESSION_TYPE=wayland dbus-run-session gnome-session

Yes

The menu, i looked around in MCC, but i think i don't go to find it without some more information what menu exactly you are pointing at.

Regarding wayland-packages, i found these installed:
lib64wayland-client0-1.21.0-1.mga9
lib64wayland-server0-1.21.0-1.mga9
lib64wayland-cursor0-1.21.0-1.mga9
lib64qt5waylandclient5-5.15.7-2.mga9
lib64wayland-egl1-1.21.0-1.mga9
lib64qt6waylandclient6-6.4.1-3.mga9
lib64kf5wayland5-5.105.0-2.mga9
kwayland-5.105.0-2.mga9
egl-wayland-json-1.1.11-1.mga9
lib64nvidia-egl-wayland1-1.1.11-1.mga9
lib64gstwayland1.0_0-1.22.3-2.mga9.tainted
x11-server-xwayland-22.1.9-1.1.mga9

That's a handful less than you described, but probably some more will be installed along the process of switching to wayland (?).

Did as you proposed.
Will wait and see, before switching to wayland as Dave suggested.

To use wayland close current session and in the login screen exist a text that indicates the type of session, by example  "Plasma (X11)" click and select "Plasma(wayland)" if you use Plasma, you can return to use normal Plasma session by the same procedure just changing again to the X11 session

First install plasma-workspace-wayland

Right, i thought i would miss some wayland-packages as mentioned in comment 12.
And so without plasma-workspace-wayland one would not see an option for wayland in the login-screen (obviously).

But as said before, i wait now for a new freeze to happen before switching to wayland.

Last night the system froze again, and after reboot (forced through power-button), sound (as usual) was gone.
Message-log comes with same messages "scheduling while atomic" etc.
The laptop was put in locked position this time. 

I was out for a couple of hours, and hoped to login again into the desktop, but i already knew something was wrong, because the clock in the lock-screen did not run and hence also no way of logging in.

So, now i will go the wayland-route, and keep you updated about experiences.

Installed plasma-workspace-wayland, which brought in some more wayland-packages.
Following wayland-packages are installed now:
lib64wayland-client0-1.21.0-1.mga9
lib64wayland-server0-1.21.0-1.mga9
lib64wayland-cursor0-1.21.0-1.mga9
lib64qt5waylandclient5-5.15.7-2.mga9
lib64wayland-egl1-1.21.0-1.mga9
lib64qt6waylandclient6-6.4.1-3.mga9
lib64kf5wayland5-5.105.0-2.mga9
kwayland-5.105.0-2.mga9
egl-wayland-json-1.1.11-1.mga9
lib64nvidia-egl-wayland1-1.1.11-1.mga9
lib64gstwayland1.0_0-1.22.3-2.mga9.tainted
x11-server-xwayland-22.1.9-1.1.mga9
kwayland-integration-5.27.5-1.mga9
lib64qt5waylandcompositor5-5.15.7-2.mga9
qtwayland5-5.15.7-2.mga9
kwin-wayland-5.27.5-1.mga9
plasma-workspace-wayland-5.27.5-2.1.mga9

There is a Plasma (wayland)-option now in the session-screen, as mentioned in comment 14.
Choosing this option presents a desktop, although everything is a bit smaller, like icons and panel. Also, single-click disappeared, but that is easy to change.
But, when i reboot (automatic login), i return into Plasma (X11) environment again.
So problem now is, that i have to log out again, choose right choice in session-screen, to return in Plasma (wayland).
It would be nice if my choice was saved, and after reboot to come back with Plasma (wayland)-session.

Also, in MCC->Boot->Setup auto-login->Default desktop does not show wayland.
Plasma X-11 and Icewm are only choices.

Alright, did some more digging and now i auto-login into wayland.
The final solution seemed to change Login Screen (SSDM)->Behavior in System Settings. Changed session there for auto-login-session, asked for root-password, rebooted and there it was.

Now fiddle around with settings, and hope for no more freezes.

Will be continued, i keep you informed.

I found information that the issue happens in some hardwares with kwin+x11+nvidia, congratulations isadora you got the winner ticket ;)

Maybe switch to Wayland is the best recommendation

Well, that is, i still have nvidia not "alive";
OpenGL Renderer: Mesa Intel(R) UHD Graphics (ADL-S GT1)

Wayland works different from X11, maybe I'm wrong but to use the discrete nvdia card you must do in X11 session

You can try installing kernel-linus and kernel-linus-devel and in the boot menu in advance options choose the kernel without flavor (desktop, server, etc), but I'm not optimist that this don't get the same fail in X11 session

I find this https://community.kde.org/Plasma/Wayland/Nvidia

We have
x11-server-xorg 21.1.8
x11-server-xwayland 22.1.9
lib(64)xcb1 1.15
lib(64)nvidia-egl-wayland1
Plasma 5.27.5

In theory can work

Yes, i ran into the same KDE-community-page.
And for my further explorations into wayland/nvidia;
last night i came to the point, no graphical desktop appeared anymore.

Slept a good night, and decided this morning to do new install of Mageia 9.

I give it a rest for some time, until then, thank you very much for your support.

Another interesting read is:

Albeit not really promising for Nvidia.

Not meaning to spam, but any information to me seems better than none.

Situation with regular freezes continued ever since initial report.
Still have to use the workaround with "BIOS-flash-update", to get workable situation. Sometimes no issue like for a month, but last week three freezes.

Did the recent nvidia and other updates change something?

Ever since my last report i stopped using NVIDIA for the graphical job.
Since then i had no crashes.

I will switch back to NVIDIA now and report about experiences.

Two weeks later, still no crashes so far.

This looks good to close.

Status: NEW => RESOLVED
