Do you have a USB keyboard/Mouse/Wifi receiver? I had this same issue whenever I had my logitech wireless keyboard and mouse hooked up. The problem was fixed by removing it...

Put The following line instead of:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

in /etc/default/grub :

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Save it. And run sudo update-grub

It usually works.

Summary:

Actually, you should remove everything from GRUB_CMDLINE_LINUX_DEFAULT="quiet splash", so it will become GRUB_CMDLINE_LINUX_DEFAULT="".


Temporary solution:

Before logging in (during boot process):

Press E in the Grub menu while Ubuntu is selected.

Update the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" portion of the file to GRUB_CMDLINE_LINUX_DEFAULT="".

Press F10 to boot.


Permanent solution:

After logging in:

sudo apt install gedit
sudo gedit /etc/default/grub

Update the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" portion of the file to GRUB_CMDLINE_LINUX_DEFAULT=""

Then,

sudo update-grub
