Turn off Nouveau

note

Before we install NVIDIA gpu, we need to make sure Nouveau which is turned off.

Steps​

  1. Check the status.

    lsmod | grep nouveau

  2. Add the following content 

    sudo vim /etc/modprobe.d/blacklist.conf

    With the following contents:

    blacklist nouveau
    options nouveau modeset=0

    Regenerate the kernel initramfs:

    sudo update-initramfs -u

  3. Adjust the resolution

    sudo vim /etc/default/grub

    Find this line: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" Change to: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

    Also, find this line: #GRUB_GFXMODE=800x4001 (the value maybe not the same.) Change to: GRUB_GFXMODE=1920x1080

    Update it:

    sudo update-grub

  1. Reboot and check the status again

Note​

Normally we do not need to turn off it during installing the GPU driver for newer computers.

Here is a very primitive environment that it did not install anything after I installed the Ubuntu 20.04 operating system. My GPU is RTX 2070 super.

I check the status of nouveau (turn on), and running kernel version compilered by gcc version and the gcc version which was installed by build-essential.

I installed the GPU driver version which is v510 by the apt command (Not the file downloaded from website i.e., NVIDIA-XXX.run).

In the installation, I encountered the MOK stage, but that was okay. Reboot it, and check the gpu status by nvidia-smi.

Here is detail configuration for this computer.
