Debian / Ubuntu / Linux Mint / LMDE NVIDIA Drivers Uninstall Guide

5. Debian / Ubuntu / Linux Mint / LMDE Uninstall NVIDIA drivers and Enable Nouveau

I assume here that you have used this guide install part to install your NVIDIA drivers. This whole process is good to run on runlevel 3. When there is no X running. So first boot to runlevel 3 using direct parameter (3) on Grub linux/linuxefi line or using “systemctl set-default multi-user.target”.

5.1 Change root user

su -
## OR ##
sudo -i

5.2 Start NVIDIA Uninstall Process

nvidia-installer --uninstall

5.3 Restore / Remove /etc/X11/xorg.conf

You can restore xorg.conf backup or remove /etc/X11/xorg.conf if you don’t have any special configuration.

5.8 Remove NVIDIA Plymouth related confs (if you enabled it or skip this step)

rm /etc/modprobe.d/nvidia.conf /etc/dracut.conf.d/nvidia.conf

5.9 Edit /etc/default/grub

Remove ‘rd.driver.blacklist=nouveau’ from end of ‘GRUB_CMDLINE_LINUX_DEFAULT=”…”‘

## Example row on Debian ##
GRUB_CMDLINE_LINUX_DEFAULT="quiet"

5.10 Update grub2 conf

update-grub2

5.11 Generate initramfs

## Backup old initramfs nvidia image ##
mv /boot/initrd.img-$(uname -r) /boot/initrd.img-$(uname -r)-nvidia
 
## Generate new initramfs image ##
dracut -q /boot/initrd.img-$(uname -r) $(uname -r)

5.12 Reboot

Run systemctl set-default graphical.target first or if you used direct grub parameter, then just:

reboot

5.13 Restore initramfs-tools and remove dracut (OPTIONAL step)

apt autoremove dracut

apt install firmware-misc-nonfree

apt install initramfs-tools

This should remove dracut and generate working initramfs using initramfs-tools instead of dracut.
