# Ubuntu – How to set ‘nomodeset’ after I’ve already installed Ubuntu

graphicsgrub2nomodeset

I know that editing the boot options line and adding 'nomodeset' solves the problem of my laptop 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

2. Press e to edit the first kernel displayed

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.
