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.
