➡️ Introduction:

NVIDIA Driver on Linux is properly the most difficult driver to install on a Linux system for everyday users. Users may experience a blank screen after installing NVIDIA Driver. To access the current system through the GUI interface, the user would need to remove the Nvidia driver.

➡️ Step 1: Exit the blank screen and access tty console login screen

To access tty console, press Ctrl + Atl + F1

➡️ Step 2: Stop lightdm service

└──╼ $ sudo service lightdm stop

➡️ Step 3: Remove the nouveau blacklist.conf

Change the directory to /etc/modprobe.d/

└──╼ $ cd /etc/modprobe.d/
└──╼ $ ls
amd64-microcode-blacklist.conf  intel-microcode-blacklist.conf
blacklist-libnfc.conf           libhackrf0.conf
blacklist-nouveau.conf          mdadm.conf
broadcom-sta-dkms.conf          r8168-dkms.conf
dkms.conf                       r8188eus-dkms.conf
└──╼ $ sudo rm blacklist-nouveau.conf 

➡️ Step 3:  Uninstall Nvidia Driver

To uninstall Nvidia Driver, run the below command:

└──╼ $ sudo nvidia-uninstall

Select Yes to run nvidia-xconfig –restore-original-backup to restore the original x configuration file.

Remove all nvidia file or artifacts using the purge command:

└──╼ $ sudo apt purge nvidia*
└──╼ $ sudo apt autoremove

➡️ Step 3: Reinstall Xserver and Nouveau Driver

Run the below command to restore Xserver and Nouveau driver:

└──╼ $ sudo apt install --reinstall xserver-xorg
└──╼ $ sudo apt install --reinstall xserver-xorg-video-nouveau 

➡️ Step 4: Regenerate the kernel initramfs 

└──╼ $ sudo update-initramfs -u
└──╼ $ reboot

To verify that Nouveau driver is being used, you can run the list command
