Ubuntu 18.04 boot issues

I upgraded my OS to Ubuntu 18.04 from Ubuntu 17.10 today after it was released.

The boot stops at a black screen saying nothing just one line, something about my SSD being loaded. The only way to start the OS is removing all the nvidia packages and replacing quiet splash by nomodeset in boot options on grub.

I need to know why this works and how do I fix the problem so that I don't have to do this all the time and start using my Nvidia drivers.

I have nvidia-390 driver installed

This helped me:

• Open Terminal and run:

  sudo gedit /etc/default/grub
  

• change GRUB_CMDLINE_LINUX=...... to:

  GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
  GRUB_CMDLINE_LINUX="nouveau.modeset=0"
  

• Delete any extras like nomodeset,acpi=off,etc and after that update grub:

  sudo update-grub
  

• Restart.

Of course its better to first test this from grub (while rebooting), editing the starting line (Ubuntu-line) with the e-key.
