View Full Version : [ubuntu] acpi=force in grub2 how to?
December 7th, 2009, 01:34 PM
I want to add acpi=force, but every reference I can find is modifying /boot/grub/grub.cfg
however, at the top of the file it says do not modify this file!
where would I add the acpi=force and what do I do next to re-generate the grub.cfg?

Edit the /etc/default/grub file:
# If you change this file, run 'update-grub' afterwards to update
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
# Uncomment to disable graphical terminal (grub-pc only)

Add it to GRUB_CMDLINE_LINUX in /etc/default/grub

it looks like according to the grub2 docs, you are supposed to add the acpi=force to "GRUB_CMDLINE_LINUX_DEFAULT", and in fact there might be a bug with GRUB_CMDLINE_LINUX.
If I want multiple parameters, is it space or command delimited?

Just like in Grub Legacy, kernel parameters are space separeted.
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force apparmor=0"

How can different bootup options be set for alternate bootups??
In particular, a choice between the default runlevel=2 and an alternate
