I just blacklisted nouveau, but I see that it is still being used. Would someone please help me understand this?

My new installation of 18.10 would freeze when logging in. To resolve this, I blacklisted nouveau in grub by updating /etc/default/grub with

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash modprobe.blacklist=nouveau"

(The solution was from NMI watchdog: BUG: soft lockup - CPU#2 stuck for 23s!, which was the issue had I experienced.)

I am glad that I am now able to successfully login, but I see that Nouveau is still being used, and this is confusing.

I thought I just blacklisted it, so why do I see it as active in Software and Updates?

What does the line modprobe.blacklist=nouveau exactly do? (Perhaps I misunderstand it).

Are there any disadvantages of adding modprobe.blacklist=nouveau to grub?

Possibly, there is a conflict between the open-source driver with that of the graphic card from Nvidia. I will write down the solution that worked for me, on a Lenovo ThinkPad P53 when installing Ubuntu 20.04 LTS, I faced some issues.

Follow the steps written below:

  1. Boot to Ubuntu, but before you login in to Ubuntu, press Cntrl+Alt+F2

  2. run the following command:

         sudo nano /etc/modprobe.d/blacklist-nouveau.conf

  3. add the 2 following lines, save & exit

         blacklist nouveau
     options nouveau modeset=0

  4. run the following command

         sudo update-initramfs -u
