本文介绍如何在Ubuntu系统中配置GRUB引导加载器，包括修改默认设置、图形界面选项、内核启动参数等，确保系统启动时的稳定性和显示效果。

1、修改文件/etc/default/grub

sudo vim /etc/default/grub

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

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`

#mjk 2010-10-26 mask
#--------------------------------------------
#GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
#--------------------------------------------

#GRUB_CMDLINE_LINUX=""

#mjk 2010-10-26 add
#--------------------------------------------
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset video=uvesafb:mode_option=1280x1024-24,mtrr=3,scroll=ywrap"
GRUB_GFXMODE=1280x1024
#--------------------------------------------

# 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=1280x1024

# 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_LINUX_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

2、修改文件/etc/initramfs-tools/modules

sudo vim /etc/initramfs-tools/modules

# List of modules that you want to include in your initramfs.
#
# Syntax: module_name [args ...]
#
# You must run update-initramfs(8) to effect this change.
#
# Examples:
#
# raid1
# sd_mod

uvesafb mode_option=1280x1024-24 mtrr=3 scroll=ywrap

3、更新(update)

sudo update-grub

sudo update-initramfs -u

4、重启机器(reboot)
