I have an HP ZBook Fury G8 17,3" FHD IPS i7-11800H 128GB/2TB SSD T1200 4A698EA. On the second SSD Windows 10 Pro is installed. Windows can use my T1200 nvidia card without problems.
On a fresh installed Xubuntu 21.10 5.13.0-27-generic with latest update I have the problem that the nvidia driver doesn't load.
sudo ubuntu-drivers list
nvidia-driver-470, (kernel modules provided by linux-
modules-nvidia-470-generic)
nvidia-driver-495, (kernel modules provided by linux-
modules-nvidia-495-generic)
nvidia-driver-460-server, (kernel modules provided by
linux-modules-nvidia-460-server-generic)
nvidia-driver-470-server, (kernel modules provided by
linux-modules-nvidia-470-server-generic)
sudo ubuntu-drivers autoinstall
or
sudo apt install nvidia-driver-470
or
sudo apt install nvidia-driver-495
installs the software without error.
reboot
leads to an 100% core load with a process that tried modprobe with no success. At the end nvidia driver wasn't loaded.
sudo dmesg | grep -i D3cold
gives me
nvidia 0000:01:00.0: can't change power state from
D3cold to D0 (config space inaccessible) vgaarb: changed
VGA decodes: olddecodes=none,decodes=none:owns=none

nvidia-nvlink: Unregistered the Nvlink Core, major

In my opinion there have been some changes in how power management works.
In BIOS I can only choose Hybrid Graphics or UHD, no Power-Mode.
I chose Hybrid Graphics, because in the other case nvidia controller is not visible. That new power management didn't allow to power on some devices (not only graphics) from within a kernel module. There must be another way to do it (in Windows it works). I think the nvidia driver didn't recognize the situation.
