I know that editing the boot options line and adding 'nomodeset' solves my laptops problem during LiveCD mode, what I don't know is how to set it at boot up through Grub2 after I've installed Ubuntu.

So, my question is, how do I set nomodeset before I boot into Ubuntu?

To edit Grub2 during the boot process try the following:

  1. Immediately after the BIOS splash screen during boot, press and hold the SHIFT button. This will display you grub containing a list of kernels and recovery options

    enter image description here

  2. Press e to edit the first kernel displayed

    enter image description here

  3. Find the line ending with quiet splash. Add your boot option before these key words - i.e. so the line looks like [...]nomodeset quiet splash
  4. Press CTRL + X to boot

Follow the steps in Coldfish's answer on how to fix the nomodeset boot option permanently so that you don't have to go through this manual procedure again.

I'm afraid I don't have a quiet splash option in that area. I don't recognize any of the lines, actually. – Dante Ashton May 2 '11 at 12:21
Dante - added some pictures to help hopefully – fossfreedom May 2 '11 at 14:04
fossfreedom. Thank you so much! I've had this problem since 10.04! My god, I would hug you if I could! :D – Dante Ashton May 6 '11 at 11:26
Where does the ro go? – Hellreaver Dec 3 '15 at 9:09
@Hellreaver - if you have "ro" in your grub entry - leave it - if you do not have it - do not add it. The picture just shows where to add "nomodeset" (just before "quiet splash") – fossfreedom Dec 3 '15 at 9:17

You should add this option to /etc/default/grub, firstly:

sudo nano /etc/default/grub

and then add nomodeset to GRUB_CMDLINE_LINUX_DEFAULT:

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

And then save by hitting Ctrl+O, then exit nano with Ctrl+X, then simply run:

sudo update-grub
