So here is what I did and what happened :
- ran your command lines for reinstall linux-modules/headers & nvidia drivers
- reboot and had grub menu, so I selected "Ubuntu" and then got error screen (see joined file) so shut-down-waited-restarted
- grub menu again, selected "Ubuntu" again and then I had the gear on login screen, so selected "Wayland" but it seems that was a bad idea : mouse cursor lagging, no night mode, launched Brave but no Brave window displayed
- reboot, back to "Ubuntu"(no wayland)
Now all seems to work (night mode, Brave display, etc - didn't try Northgard but I guess it's ok too). So thanks a lot. Web pages and app launch are still slow in my opinion but maybe it is another problem?

So I guess I can't use Wayland?
