Thread: how to change file after install for first time with acpi=off command?


i installed ubuntu first time on unformated hard drive. wouldn't work selecting 'start or install ubuntu' used acpi=off command. supposedly need change file now. file change , how?

you might make sure system, once installed, going work if boot without option.

@ grub menu (hold down shift key during boot if doesn't appear), highlight top entry , press 'e' edit entry. cursor 'linux' line if "acpi=off" appears there , use backspace key remove it. ctrl-x or f10 boot.

if boots , runs properly, see if command set in grub 2 configuration file:
code:
grep "acpi" /etc/default/grub
if find setting in line containing "grub_cmdline_linux_default=" need edit file root:
code:
gksu gedit /etc/default/grub
remove "acpi=off", save file , run:
code:
sudo update-grub
