grub does not use settings from /etc/default/grub

  • 772

I setup a new ubuntu quantal system and edited /etc/default/grub as follows:

# 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"

Afterwards I ran update-grub which reported no errors. However /boot/grub/menu.lst still has "quiet splash" in the kernel command line:

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

How can fix it, so get rid of the "quiet" and "splash" options?

    Just so you know, 12.10 (and almost most other Ubuntu versions) uses Grub2 and not Grub. One of the major differences between Grub and Grub2 packages is that there is no /boot/grub/menu.lst file and it has been replaced by /boot/grub/grub.cfg.

    Your changes to the /etc/default/grub will not update the /boot/grub/menu.lst file and the command update-grub actually only updates the /boot/grub/grub.cfg file.

    So, if you would check the /boot/grub/grub.cfg file, you can notice that the kernel command line would no longer have the "quiet splash" in it.
