hi guys,

i have googled on how to disable or blacklist nouveau and i dont know the best way to do it and i would like to know your opinions

1st-

edit the line "GRUB_CMDLINE_LINUX" in file "/etc/default/grub"

GRUB_CMDLINE_LINUX="crashkernel=auto rhgb quiet rd.driver.blacklist=nouveau nouveau.modeset=0"'

make a new file "/etc/modprobe.d/blacklist.conf" and append 1 line to it

blacklist nouveau

2nd

or make a new file "/etc/modprobe.d/blacklist.conf" and append 2 lines to it

blacklist nouveau
options nouveau modeset=0

what do you think

thanks,
rob

The second method that you posted is the best choice. I say that because that is what I've found from all of the searching I've done over the years. It's also the most practiced method that I have seen here in the forums.

thanks ztcoracat

i imagine i need to run this command after i make the changes for the modprobe changes

dracut /boot/initramfs-$(uname -r).img $(uname -r)

or can i just restart and it takes affect straight away

if i was to do the first option i would eed to run this command wouldnt i aswell

grub2-mkconfig -o /boot/grub2/grub.cfg

You're Welcome.

Yes if you were to perform the first option you would have to run:
I'm not sure about the dracut command. I've never used it:-
You may want to do some searching online to make sure.

What distro are you running?

think the dracut command is for this

Backup your old initramfs and then build a new one

mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img
dracut /boot/initramfs-$(uname -r).img $(uname -r)

but i see no reason to make a backup and re create my initramfs?

my workstations are on centos 7 1804 min

Ok, yeah, than that makes sense with CentOS:-

Those directories are associated with the rootfs; it's up to you if you make a backup.

Since the boot loader loads the kernel and the initramfs image into memory and starts the kernel and you will be updating grub anyway it's most likely not necessary to backup and re-create your initramfs:-

How did things go?

you do need to rebuild the initramfs after you add in a new file in "/etc/modprobe.d/" ie if you add "blacklist.conf"

then you do -

dracut /boot/initramfs-$(uname -r).img $(uname -r) --force

but its wierd as i have got another file i added to block all usb storage and that works and i didnt need to run the dracut command -

Method 1 – Fake install

In this method, we add a line ‘install usb-storage /bin/true’ which causes the ‘/bin/true’ to run instead of installing usb-storage module & that’s why it’s also called ‘Fake Install’ . To do this, create and open a file named ‘block_usb.conf’ (it can be something as well) in the folder ‘/etc/modprobe.d’,

$ sudo vim /etc/modprobe.d/block_usb.conf

& add the below mentioned line,

install usb-storage /bin/true

Now save the file and exit.

all i did was reboot the centos 7 machine and i could no longer see any usb storage i plugged in

Does the usb storage show in lsusb or fdisk -l (small letter L)?

no when i attach a usb storage drive in and when i do "fdisk -l" to show all my drives plugged in it doesnt show up

and all i did was reboot my machine after making that file in modprobe, so thats what i dont understand as i would had thought it would had been the same

maybe its because its a kernal driver the nouveau bit and usb isnt?

When I was running CentOS my usb drives and memory stick weren't being seen either.

I had to install ntfs-3g:-

mmmm... not having any luck, i ned to run the "dracut -f" even if the file is in the modprobe folder and even after a reboot

i tried another way but didnt work

echo 'omit_drivers+="nouveau"' >> /etc/dracut.conf.d/nouveau.conf

reboot and its still there

so i have just done this

echo 'install nouveau /bin/false' >> /etc/modprobe.d/nouveau.conf

Did it work?
