Updating the grub bootloader and setting various options with Ubuntu or Mint.

The grub bootloader used by Ubuntu or Mint is very easy to work with when you wish to add a new kernel or customize the look and feel of the Grub2 bootloader. The listing below is my /etc/default/grub file. This file may be customized with your current desktop resolution so that when the grub menu appears it will be in the same resolution as your desktop. After modifying this file, run sudo update-grub to update the /boot/grub/grub.cfg.

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'
 
GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""
 
# Uncomment to enable BadRAM filtering, modify to suit your needs
# This works with Linux (no patch required) and with any kernel that obtains
# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)
#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"
 
# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console
 
# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
GRUB_GFXMODE=1024x600
 
# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true
 
# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_RECOVERY="true"
 
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

I have disabled the generation of the recovery mode menu entries, this makes the grub menu less cluttered and simpler to read in a hurry. There is a nice tutorial here detailing how to install a set of nice splash images for Ubuntu or Debian. http://www.securitronlinux.com/bejiitaswrath/cool-miscellaneous-wallpapers-and-tips-for-debianubuntu/. And there is a link to a tutorial that explains this in more depth.
