Ubuntu – Can’t boot up Ubuntu after changing grub file with nomodeset

grub2nomodesetscreen

So I was trying to get Ubuntu to be able to change the screen brightness correctly, and in one of the forum posts, someone suggested to try to change the grub file with "nomodeset." After I did so, my Ubuntu boots up to a full purple screen and gets stuck there.

I pretty much need to be able to modify my grub file again and change it to what it originally was. How can I do that?

Help please?

EDIT:

I tried booting into recovery mode, but I can't get past the black screen with all the text written on it. I think I'm getting a udevd error related to my graphics card.

How to change boot options temporarily

  • Boot your system.
  • Hold Shift to show the Grub-Menu if Ubuntu is your only system.
  • Go to the menu entry you want to (temporarily) change and hit e.
  • Delete the "nomodeset" from the kernel options.
  • Hit Ctrl + x to continue booting.
