Boot your computer. When the GRUB menu (the one that lets you select your OS) shows up, select Ubuntu and press 'e'. If this menu does not appear, keep pressing Shift right after the computer boots until it does.

After pressing 'e' on Ubuntu you will see some kind of text editor. Find the line that begins with linux and go to its end. Remove nomodeset from the end of the line and press F10. Ubuntu should boot.

Open a terminal window and run the following commands:

sudo gedit /etc/default/grub

Change the line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash".

Save the file and exit. Then run:

sudo update-grub

Your system should be fine. Reboot and test it.
