我设置了一个新的 ubuntu quantal 系统并进行了/etc/default/grub如下编辑：
# If you change this file, run update-grub afterwards to update
# /boot/grub/grub.cfg.
GRUB_DEFAULT=0
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
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=640x480
# Uncomment if you dont want GRUB to pass "root=UUID=xxx" parameter to Linux
GRUB_DISABLE_LINUX_UUID=false
# Uncomment to disable generation of recovery mode menu entries
GRUB_DISABLE_LINUX_RECOVERY=false
# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"
之后我运行update-grub，没有报告任何错误。但是/boot/grub/menu.lst内核命令行中仍然有“quiet splash”：
title Ubuntu, kernel 3.5.0-17-generic
uuid 3f26e165-5167-43e5-8fa2-aa55f7919d2a
kernel /boot/vmlinuz-3.5.0-17-generic root=UUID=3f26e165-5167-43e5-8fa2-aa55f7919d2a ro quiet splash
initrd /boot/initrd.img-3.5.0-17-generic
quiet
title Ubuntu, kernel 3.5.0-17-generic (recovery mode)
uuid 3f26e165-5167-43e5-8fa2-aa55f7919d2a
kernel /boot/vmlinuz-3.5.0-17-generic root=UUID=3f26e165-5167-43e5-8fa2-aa55f7919d2a ro single
initrd /boot/initrd.img-3.5.0-17-generic
如何修复它，从而摆脱“安静”和“飞溅”选项？
答案1
请注意，12.10（以及几乎所有其他 Ubuntu 版本）使用的是 Grub2，而不是 Grub。Grub 和 Grub2 软件包之间的主要区别是没有/boot/grub/menu.lst文件并且已被替换/boot/grub/grub.cfg。
您对 的更改/etc/default/grub不会更新/boot/grub/menu.lst文件，而该命令update-grub实际上仅更新/boot/grub/grub.cfg文件。
因此，如果您检查该/boot/grub/grub.cfg文件，您会注意到内核命令行中不再有“quiet splash”。
