newbie looking for help with suse 9.2 power management

dollydoll · 01-18-2005, 08:30 PM

Hi there:

I've already posted this somewhere else, but I guess here it fits better:

Linux Suse 9.2 doesn't shut down/reboot from KDE/shell!!

*I tried already:

1-changing configuration of power management from the Yast2Module.
Please note that there's no ACPI disabling option.

2-disabling ACPI in the BIOS. It worked only once, then suse didn't want to shut down again.

3-from command line typing: init 0 and demsg and seeing what was going on...that was the sol'n from musicace_man

4-typing halt or reboot, or shutdown -r now, etc...
none of the above worked!! I 'm quite discouraged!

5-I read in the Suse Admin guide, that the ACPI can be disabled in the kernel, by typing a command like acpi = off, or something like that. My problem now is that I don't know anything about the kernel, its configuration, compilation whatsoever...

ANY hints, pleeease?

Note: I am not a pro at this so this is mearly a point in a direction which I think will help.

You can probably use it as an option in your bootloader. I know on Grub when it's waiting for an OS selection there is a command line under all the selections. If you use LILO it might be different and if you change your LILO options you have to do something special before you restart (I forget what you have to run).

It's kind of vague but I hope it helps in your search.

Noted: I'm booting with grub, not lilo...are you saying there's a command line option within the booting options window?
If I manage to access it, what do I do once there?
thank you!

Try this link: Grub . It's a section from the SuSE administrator's guide about Grub and its modification.

what exactly do you mean ?

if you type halt/shutdown/reboot as an ordinary user nothing will happen of course.

or does your computer refuse to shut-off after system halt has been established ?

it refuses to shut-off!
(I did, as a user, of course, cos I'm a newbie in this, but I did also as a root, and actually, it didn't want to shut-off..)
thanks for replying!!

ok. that problem sounds familiar to me.

maybe the stuff I had to do will work for you as well.
here's what has helped my computer to shut-off and recognize the power-button:

first test this:

DISABLE "powermanagement is controlled by APM" in your bios - or the most equivalent option.

then at boot time when GRUB waits several seconds for you to choose which kernel to run or TO ENTER BOOT PARAMETERS, press the TAB-key and enter

Code:

acpi=force

then press enter to make your machine boot.

after the boot process has been finished log in and do this

Code:

dir /proc/acpi/

if your kernel has accepted to use acpi you should see something like

Code:

dr-xr-xr-x  2 root root 0 2005-01-21 10:53 ac_adapter
-rw-r--r--  1 root root 0 2005-01-21 10:53 alarm
dr-xr-xr-x  2 root root 0 2005-01-21 10:53 battery
dr-xr-xr-x  4 root root 0 2005-01-21 10:53 button
-rw-r--r--  1 root root 0 2005-01-21 10:53 debug_layer
-rw-r--r--  1 root root 0 2005-01-21 10:53 debug_level
-r--------  1 root root 0 2005-01-21 10:53 dsdt
dr-xr-xr-x  2 root root 0 2005-01-21 10:53 embedded_controller
-r--------  1 root root 0 2005-01-20 11:20 event
-r--------  1 root root 0 2005-01-21 10:53 fadt
dr-xr-xr-x  2 root root 0 2005-01-21 10:53 fan
-r--r--r--  1 root root 0 2005-01-21 10:53 info
dr-xr-xr-x  2 root root 0 2005-01-21 10:53 power_resource
dr-xr-xr-x  3 root root 0 2005-01-21 10:53 processor
-rw-r--r--  1 root root 0 2005-01-21 10:53 sleep
dr-xr-xr-x  2 root root 0 2005-01-21 10:53 thermal_zone
-rw-r--r--  1 root root 0 2005-01-21 10:53 wakeup

if the directory is EMPTY or non existant it won't work.

in case this little surgery was successfull do this

Code:

 /etc/init.d/acpid stop

and

Code:

 /etc/init.d/powersaved restart

if you are lucky your computer will now shut-off and even respond to the power button as it should.
with KDE you can use the KPOWERSAVE applet or YAST to configure your computer's powersave behaviour.

to make this permanent just do this:

Code:

joe /boot/grub/menu.lst

you'll see something like this:

Code:

    I    /boot/grub/menu.lst                                   Row 1    Col 1   11:03  Ctrl-K H for help

hope it works for you as well.
