Nouveau messages on journalctl while using nvidia proprietary driver

Hello,
I am quite confused about the whole graphics thing works on linux especially with optimus, but:
I have installed the official nvidia driver, why do I still have messages(complains and errors) regarding nouveau?

maybe the nvidia packages missed to disable the kernel module?

Unlikely. Which packages did you install?

pacman -Qs nvidia

Did you reboot after that? As you were instructed by the package installation?

Re: Nouveau messages on journalctl while using nvidia proprietary driver

no ok, the kernel module is correctly disabled in /usr/lib/modprobe.d/nvidia.conf. Could someone explain me these messages? My possible explanation is becuase nouveau is compiled inside the kernel, so it doesn't really disappears.

Thanks for the answer, I've installed nvidia with pacman -S nvidia, picking the one with libgvnd and I've rebooted.

$ sudo pacman -Qs nvidia
local/libvdpau 1.1.1-2
    Nvidia VDPAU library
local/nvidia 381.22-2
    NVIDIA drivers for linux
local/nvidia-utils 381.22-1
    NVIDIA drivers utilities

I just did a clean install, so it is unlikely I screwd up packages/configurations. All I did till now was pacman -S.

Re: Nouveau messages on journalctl while using nvidia proprietary driver

check lsmod to see if the module is loaded, also since you didn't specify which command you ran: You are aware that the journal is stored on your hard disk? That might well be from an earlier boot from where nouveau was still active, if you want to know what happens on your current boot use either dmesg or journalctl -b which will only show you the kernel or journal log respectively, since the last boot.

And don't double post, you can edit a post to append new information if no one has answered in between
