I run: "shutdown -h now"; I get the message "power down" (or power off) but my computer doesn't turn off - I have to shut down it manually. Can someone tell me, how to get my slackware9-box to turn off?

You need to enable the APM module. Do a 'modprobe apm' and then it should work. To enable the apm permanently, look for the line in /etc/rc.d/rc.modules which refers to apm (its something like #/sbin/modprobe apm and remove the #. 'lsmod' should show the apm module running if all is well. Good luck and happy slacking.

on my system i'd got the same error. it seems that apm doesn't function, so i decided to compile a new kernel using acpi which works pretty good for me.

I tried it and it works! Thx!

Same here. APM wouldn't work, but ACPI with a new kernel works.

root@linux:~# modprobe apm
/lib/modules/2.4.20/kernel/arch/i386/kernel/apm.o.gz: init_module: No such device
/lib/modules/2.4.20/kernel/arch/i386/kernel/apm.o.gz: Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20/kernel/arch/i386/kernel/apm.o.gz: insmod /lib/modules/2.4.20/kernel/arch/i386/kernel/apm.o.gz failed
/lib/modules/2.4.20/kernel/arch/i386/kernel/apm.o.gz: insmod apm failed

What should I do?

vi /etc/rc.d/rc.modules
uncomment the line for the APM (save and close rc.modules)
insmod apm
lsmod (it should be listed apm)
shutdown -h now
It will power off on its' own now.

I am curious, what does apmd do, and is it in the init scripts by default, and do I need it to have my machine power down?
Thanks

As far as I recall, APM stands for Advanced Power Management??? apmd is the daemon, i.e. the program that monitors the apm from your computer's BIOS. All that means is that if you want your PC to power itself off when you shutdown, it needs to be running! Its more vital on laptops where it also helps with battery management.

I think I've got that right...

Dear,

I have the same problem mentioned here.

I verified the line (#/sbin/modprobe apm) for APM in rc.modules (/etc/rc.d/rc.modules) and it really was commented. I uncommented it and tried to use the following command:

“insmod apm”

And the result I got is:

"insmod: can't read 'apm': No such file or directory"

How can I deal with? Because I guess I need to do it before use the command "modprobe apm". Could you help me please?

Thanks in advance!

Best regards,
MPRT

Er no.

insmod requires you to give the full path to the module and you must have any modules that the module depends on loaded already

modprobe is the magic baby that does all the hard work for you

tl;dr use modprobe

Dear Wildwizard,

thank you for the post!

In fact, I would like to use the command “shutdown –h now” to turn off the computer and power it down without need to handle it.

However it doesn’t work in Slackware 13 with the single board computer I’ve been using.

So, I tried to use the command “modprobe apm” but the result is:
"FATAL: Error inserting apm (/lib/modules/2.6.29.6-pm/kernel/arch/x86/kernel/apm.ko): No such device”

After that I verified the line for APM was commented in rc.modules. I uncommented it and tried to use “insmod apm” but it also doesn’t work.

I’m learning about Linux and I like it very much but I still don’t have the knowledge to solve this problem.

After the FATAL error what can I do?

Thanks!
MPRT

I don't think APM is supported anymore, try instead to put 'pci=nomsi' in your /etc/lilo.conf append line, then run 'lilo' as root then reboot, then try shutting down.

Do you have the nvidia driver installed ? Just wondering.

Dear H_TeXMeX_H,

thank you for the post!

I did append=" vt.default_utf8=0 pci=nomsi" in lilo.conf file, then I run lilo.

After that, when I try to use the command "shutdown -h now", the last lines are showed:

md: stopping all md devices.
Shutdown: hdb
System halted.


Just to be clear, the system uses hdb instead hda.

After system halted, I need to handle it by button.

In any case, thanks for all information!

Regards,

MPRT

On Intel standard architecture machines the power off function is handled by acpi. (Advanced Configuration and Power Interface). This is the replacement for apm. (Advanced Power Management).

So your kernel needs to load the acpi module or have it compiled into it.
