NVIDIA-SMI has failed because it couldn't communicate[Solved]

I failed to install the nvidia driver. I followed the Custom kernel section 1.2, and I got the following message with nvidia-smi.

@arch ~]$ nvidia-smi 
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

I have just installed the arch for about two weeks and could not solve it. I referred to this post, but it is a different kernel. I also provide my PC information:

Re: NVIDIA-SMI has failed because it couldn't communicate[Solved]

nvidia-smi only work if you using 'nvidia' module, currently you are using nouveau.

did you installed kernel headers (e.g. linux-zen-headers)? I see you installed nvidia-dkms, so it need the headers.

Re: NVIDIA-SMI has failed because it couldn't communicate[Solved]

Well, here comes something really interesting...
I installed the linux-zen-headers yesterday like this BEFORE I posted the previous question:

@arch ~]$ pacman -Qs linux-zen-headers
local/linux-zen-headers 6.0.2.zen1-1
    Headers and scripts for building modules for the Linux ZEN kernel

I failed to have nvidia-smi work, even after shutdown and reboot. But today, I woke up and found it works:

@arch ~]$ nvidia-smi

That is like a miracle. But, it works with a side-effect: I cannot use an external monitor as xrandr cannot detect it:

lspci also works:

Now the old problem was solved, but a new one was incurred. Shall I start a new post and mark this as solved, or you help me with a new problem?

Re: NVIDIA-SMI has failed because it couldn't communicate[Solved]

There's no miracle - installing the headers allowed nvidia-dkms to be built for that kernel and you end up using it w/ the reboot.

The other output isn't available because this is an optimus system and the nvidia driver doesn't seem available or usd for X11.
