NVIDIA kernel module missing falling back to nouveau

I try to install driver on FEDORA 35, Ubuntu 21.10
Zbook G8 with t1200

Same issue on 510.47.03

Installed from fedora official repositories and also from *run from nvidia.com

Thank You

Please see this:

Seems like there is a real issue behind:

Do you confirm that you aren’t using any dedicated xorg.conf snipet ?

@kwizart it’s a kernel bug in kernels 5.13, 5.14 and 5.16 (don’t know about 5.17) which affects mobile intel core-i 11th gen systems so that the nvidia gpu is turned off after boot and can’t be turned on. Don’t know whether this is a bug in pcie pm or acpica.
