Changing the screen resolution on 12.04

Question

I am running 12.04 within Parallels 7 on an 11" MacBook Air.

I'm trying to set the display resolution to the native 1366 x 768 but Ubuntu doesn't list this as an option. How can I add the correct resolution to the options?

Answer 1

In a terminal:

sudo gedit /etc/default/grub

Search for the line with quiet splash, and change it to quiet splash nomodeset. Save the file.
Then:

sudo update-grub

Reboot your VM.

In most of the cases this will help.
