Ubuntu 16.04 - How to disable Nvidia driver from GRUB?

Solution 1:

I got it to work!

Here's what I did:

1. Booted into recovery mode with root cmd prompt.
2. Mounted the drive with "mount --options remount,rw /"
3. Purged the drivers with "sudo apt-get purge nvidia-*"
4. At this point I was able to boot into Ubuntu, went to "Additional Drivers" and selected the latest available Nvidia driver.
5. Even after install, the driver wasn't see my card. I had to go to tty1 (CTRL+ALT+F1) and run "sudo service lightdm restart". My screen flickered a few times and then came back up in my monitor's native resolution.

Hope this helps others who are stuck.
