Xubuntu 8.04 does not shut down my computer

Asked by steppen wolf on 2008-05-08

Hi to all, I am new here...

Yesterday I have successfully installed Xubuntu 8.04 Hardy Heron, and everything is fine...but my computer is not able to shut down. The last line of code generated during shutdown says:

[ 142.821923] System halted

I can hear my HD stopping and all, but then I have to turn off the computer using the power button. How can I get the computer to shut down on its own?

I am wondering if this could work (http://ubuntuforums.org/showthread.php?p=2595626), but the truth is that I do not know where to execute the commands either - and other people are saying that acpi=force makes their computer slow (the reason why I uninstalled WinXP to start with...)

Thanks in advance for your help!

P.S. At startup, it also says that my BIOS (1997) is too old.

I found a way to solve this problem. Here is the solution for people running Xubuntu Hardy Heron and with a BIOS from before 2000.

1) Go to the terminal (Applications/System) and enter this line of code:

sudo mousepad /boot/grub/menu.lst

2) Now a Mousepad file will open. Scroll down all the way till you see

End Default Options

3) Find the paragraph where it says something like:

Ubuntu 7.10, kernel 2.6.22-14-generic
(hd0,0)
/boot/vmlinuz-2.6.22-14-generic root=UUID=419086cc-9136-45e9-9369-d7fe44edff76 ro quiet splash
/boot/initrd.img-2.6.22-14-generic

4) See where it says "splash"? Enter a space, then write (on the same line):

acpi=force apm=power_off

5) Save the document, exit, restart the computer, log in again and try to shut down. It might just work.

I also tried your advice on a Vaio PCV-RX74M, Ubuntu Jaunty (kernel 2.6.28-15-generic), and it worked great! Thanks a lot, steppen wolf :)

Please add the parameters

acpi=force apm=power_off

to the defs options section of your /boot/grub/menu.lst

and then give to your system the

sudo update-grub

terminal command otherwise at next kernel upgrade you will have this issue again.

Hope this helps

It solves my doubt: how to have it updated automatically when installing a new kernel. Thank you maracoba, now my computer shuts down properly by itself :) and I won't have to For this configuration, I tried to use only acpi=force (no apm=power_off) and it worked too, so I used this only param.

PS: for those who get in trouble, may be it can help: you don't have to remove the sharp (#) at the begining of the defoptions of your /boot/grub/menu.lst; just add the param(s) at the end of the line, as follows:

# defoptions=quiet splash acpi=force

It's described on the same file:

### BEGIN AUTOMAGIC KERNELS LIST
## lines between the AUTOMAGIC KERNELS LIST markers will be modified
## by the debian update-grub script except for the default options below

## DO NOT UNCOMMENT THEM, Just edit them to your needs
