Booting Ubuntu with "acpi=off" grub parameter

Solution 1:

Using acpi = off disables your Advanced Configuration and Power Interface off temporarily while booting Ubuntu. If you have to add the acpi = off to let ubuntu boot successfully, it means that the ACPI on your computer isn't compatible with this version of ubuntu.

I don't think using acpi = off repeatedly wrecks your computer, because it only disables ACPI temporarily.

However, if you don't want to add the acpi = off parameters every time you boot, you can disable the new card (BIOS) or disable ACPI (also from the BIOS). Use the second option if you can't find the New Card Interface.

But, if you have Windows, disabling ACPI from the BIOS may wreck Windows and the computer will force you to reinstall it. So do that if you have a hidden windows recovery partition in your computer.

Solution 2:

I've recently purchased a HP Envy 17 j053ea machine to take advantage of the i7 and oodles of memory. Cutting to the chase I suffered from many issues with this install. The wireless didn't work, the screen "black screened" during installation and thereafter during booting. The get around for the black screen was the boot option acpi=off, but this of course meant that the laptop would not suspend when I closed the lid which is clearly suboptimal. After searching for the past two days I have found many good articles/explanations of acpi and a much better option:

For info on acpi see: http://www.tldp.org/HOWTO/html_single/ACPI-HOWTO/

For more info see: https://wiki.archlinux.org/index.php/ACPI_modules

Then I found: No ACPI support for my PC, what can I do? from irrational_john ... way to go .. acpi=ht didn't work but pci=noacpi has done the trick. For your hardware I'd recommend John's approach pf cycling through the options he provided:

nolapic
noapic
acpi_osi=“Linux”
acpi_osi=“Windows 2006”
acpi=ht
pci=noacpi
acpi=noirq
pnpacpi=off

With this in hand abd to address “wub's” .. on point answer above, once you find the one that works:

bash# cd /etc/default
bash# sudo vi grub
# Use the vi editor to add the boot options to the line  

GRUB_CMDLINE_LINUX_DEFAULT=

and make it (in my case):

GRUB_CMDLINE_LINUX_DEFAULT=“quiet splash pci=noacpi”

finish with:

bash# sudo update-grub
bash# sudo reboot

Solution 3:

I had the same problem.

This is the fix:

Edit /etc/default/grub.

In the grub file, change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to be GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux acpi_backlight=vendor".

Then do sudo update-grub and reboot! Courtesy of wub.
