set acpi_osi=Linux

Postby kwevej » Sun Sep 26, 2010 4:16 pm

This could help (especially @ laptops), if u have issues with CPU fan control ; multimedia keys; perhaps also hibernation and shutdown.

Run terminal and run:

Code: Select all

sudo gedit /etc/default/grub

and then change

Code: Select all



Code: Select all

GRUB_CMLINE_LINUX_DEFAULT="quiet splash acpi_osi=Linux"

next update /boot/grub/grub.cfg by running

Code: Select all

sudo update-grub

I know this thread is mega-old, but it worked like a charm for me on a new install of Mint 15 MATE 64-bit :D

My system would hang on shutdown. It would go through the "system is going down for a halt NOW! going to run level..." etc. and the screen would blank, but the computer would stay powered on (fans running, lights on) until manually holding the power button. After adding the above acpi_osi=Linux, halt works as expected!

A couple things though:

I recommend creating a backup of important files (any file you need to sudo edit) before editing

Code: Select all

sudo cp /etc/default/grub /etc/default/grub_bkup

and I noticed that immediately after updating the grub file, the computer still hung when trying a halt - the update didn't take effect until after a full reboot.

Thanks a million!

hey yo !! thanks dude !!!

edit : mmmh.. actually, it solves my "stand by" problem , but not my hibernation problem unfortunately , ...
edit2 : mhhhhh perhaps it's because my swap was not same size or greater than my 4go ram...
