Nvidia module loading issues half of the time

Hi everyone !

Since I upgraded to Zorin 18, I have this issue where the nvidia driver does load my nvidia graphic card only half of the time.
If the boot uses X11, nvidia modules are properly loaded (even if then I switch to a Wayland session when I log in).
But if the boot uses Wayland, the nvidia devices (/dev/nvidia*) are not created and the udev process that spawns "/sbin/modprobe nvidia-drm" is killed because of a time out.

Also, when the nvidia devices (in /dev) are not present, the graphic card is well detected by fastfetch or lspci, but just not usable.

I attach logs files (one when the nvidia devices are created/loaded, the other one when they're not).

When loaded : booting log (no issues - X11) - Pastebin.com
Not loaded/usable : booting log (nvidia gpu unusable - Wayland) - Pastebin.com

Final note:
Changeing the nvidia driver's version (for exemple use 590/595) has not effect, and the last time I changed it I had to reinstall Zorin OS because it broke my wifi, touchpad and other drivers

Don't know what other things I can add to help, don't hesitate to ask me !
Thanks !

Also :

Secure boot is disabled, modset is set to 1 (as the default) and I don't have dual boot

Nvidia and Wayland is a bit difficult when You don't have a current Wayland Implementation. If it runs fine on X11, I would simply suggest to stay on it.

If You prefer Wayland ... I see, You run the new 7.0 Kernel. Did you tried it with switching back to the older 6.17 Kernel to check if it behaves different? If not, I would suggest to try that.

There was an update to the 580 driver yesterday went from 580.159.03 to 580.173.02....and as @Ponce-De-Leon suggested using X11 with the nvidia driver works better

Thanks for you answer!

I really prefer Wayland over X11 (with X11 I have some touchpad issues on some apps)

I'll try to use the 6.17 kernel to see if it changes something :raising_hands:

took me abit trying to find the vid card you have...but that card uses the 595 drivers from nvidia....shows thats a laptop card is that what ya got?

Yep it's a laptop GPU.
I'm using the 580 driver but with the 595 I have the same issue (I recently reinstalled Zorin OS and it automatically selected the 580, while before the reinstallation I was on the 595)

I found this :

It seems that the guy has a very similar configuration to mine, and the same issue (the logs are the same when he success/fails to load nvidia driver).

But the solution for her was to set modeset to 0, which I saw somewhere to be counterproductive.

I'll make my tests next week and keep you up to date !
