Unlike the other answers, I assert that the
blacklist keyword will not actually blacklist the driver.
Let me explain what that keyboard actually does.
blacklist does not blacklist the driver at all. The most it can do is offer a gentle suggestion. What you are writing is not a rule, but rather a guideline for one small portion of the boot process. Ubuntu can decide to break your
blacklist guidelines at any time. You can clearly see that
blacklist nouveau does not actually what it claims to do, because you can still do
modprobe nouveau with the guideline in place. Don't offer any
nouveau for any ifs and buts, if
nouveau is blocked like you want, it won't even get to see its options.
What you actually need is the
install [module] /bin/false line:
echo 'install nouveau /bin/false' | sudo tee /etc/modprobe.d/blacklist-nouveau.conf
sudo update-initramfs -u
sudo modprobe nouveau - Yes, please actually try this. You will instantly see the night and day difference that
install nouveau /bin/false makes compared to the useless
