Ubuntu won't boot properly

Solution 1:

Seems you are a victim of Nvidia Optimus :)

Can you try adding nouveau.modeset=0 to your kernel parameters and boot if it doesn't work try with nomodeset.

1. If you don't know how to add a kernel parameters when in boot menu press e key when highlighting the kernel.

2. You should be able to see and edit the commands associated with the highlighted kernel. Find the line starting with linux and add the parameter end of the line (after quiet splash). Press CTRL + x or F10 to boot.

Edit: After booting to your system fire up a terminal and remove Nvidia drivers with;

sudo apt purge nvidia*

Thanks for pointing out @ChanganAuto, you can uninstall binary drivers with running the .run file again;

./NVIDIA-Linux-x86_64-version.run --uninstall

I assume you didn't installed bumblebee or something similar. Launch Software & Updates Select Additional Drivers tab then click to Using NVIDIA driver metapackage from nvidia-driver-470 (proprietary, tested) click Apply changes.

Just in case rebuild kernel modules with;

sudo update-initramfs -u

Reboot your computer you are good to go.
