#GRUB_GFXMODE=640x480
* You can remove the # symbol to make this line active. The entry sets the resolution of the graphical menu (the menu text size). It provides resolutions supported by the user's graphics card (e.g. 640x480, 800x600, 1280x1024, etc). The setting applies only to the boot menu display, not the resolution of the operating system that boots.
o Tip: Setting the same resolution in GRUB 2 and the operating system will decrease boot times slightly.
* Although not required, the user can also specify the color bitdepth by appending it to the resolution setting. An example would be 1280x1024x24 or 640x480x32.
* The user can also add multiple resolutions. If GRUB 2 cannot use the first entry, it will try the next setting. Settings are separated by a comma. Example: 1280x1024x16,800x600x24,640x480.
* If using a splash image, make sure the resolution setting and the splash image size are compatible.
* If using an entry that produces a "not found" message when running update-grub, try adding or changing the color bitdepth.
* Resolutions available to GRUB 2 can be displayed by typing vbeinfo in the GRUB 2 command line. The command line is accessed by typing "c" when the main GRUB 2 menu screen is displayed.
* If this line is commented (#) or the resolution is unavailable GRUB 2 uses the default setting determined by /etc/grub.d/00_header.
* For a guide to changing resolutions when using a splash image see the Splash Images & Theming section.
