What is safe graphics mode?

While @marosg answer is excellent, I just want to add..

nomodeset parameter is highly in use since the previous releases and lot of people are looking for a workaround or solution in the web while their first attempt failed due to graphics problem..

While there are answers how to edit the kernel parameter while booting the Live USB.

With the addition of this boot entry, it gives the user a fast way to try Ubuntu/ Install Ubuntu here onwards..

As I have tried to view the parameters for these new entries...
it just added nomodeset no other parameters other than default.

Please have a look on below images..

Here are few links to previous Questions about nomodeset.

  • How to set nomodeset GRUB2 before I've installed Ubuntu
  • How do I set 'nomodeset' after I've already installed Ubuntu?
  • Nomodeset Installation
  • Black Screen without nomodeset
  • How to boot without 'nomodeset'?
  • Is nomodeset still required?

Special reason why they include it is called progress :) There are cases when system cannot correctly initialize graphics card and after boot you get just a black screen. Safe graphics mode sets boot parameters the way which allow to boot and be able to login and correct things. If it works ok it will be probably included in later releases as well.
