I'm using Gnome 3.6.2 with Ubuntu 12.10, my screen resolution is currently 1680x1050, but in GRUB it was something different. First I used /etc/default/grub to uncomment the resolution line and change it to the same resolution I usually use. When that didn't work I downloaded GRUB customizer and changed it there. That didn't work so I ran this:

 sudo hwinfo --framebuffer

and got this output:

The resolution I have GRUB set to now doesn't appear on that list. Maybe that's why it's resisting my changes? Is this a list of all the resolutions my video card can handle, or just a list of resolutions? I tried out a couple of them to see if they looked okay but none of them seem to be anywhere close to the ratio I use now (16:10). The only thing that bothers me is that the words are cut off and my pretty picture won't show. I'm just looking for a resolution that'll show both boot options.

That happens to be the first thing I tried when I searched it, which led me to uncomment the line in etc/default/grub. Sorry I forgot to mention it. –  MelodiesonMusic Feb 2 '13 at 23:46

Grub Customizer can help you.

Installation of Terminal:

sudo add-apt-repository ppa:danielrichter2007/grub-customizer && sudo apt-get update && sudo apt-get install grub-customizer

Run it and see the section Appearance Settings.
