Power down

[phunni]

ok - I've just emerged the latest kernel sources from gentoo (by latest I mean gentoo latest, not kernel latest) and I'm going to recompile using my old config, which has worked nicely for me.

 

There is at least one thing I think I will need to change, however, but I'm not sure how to do it. Ever since I first compiled and ran my own kernel, my computer has not been able to automatically power down. It get's to the point where it says "power down" but I still have to manually switch it off

 

Is there an option in config which will enable my computer to shut itself down? I assume this is at kernel level

Are you apm or acpi? I had the same prob....I'm acpi/apm :roll: What can I say, it's a 2.5 year old OEM cheap....well you get the picture. Here's what I did. In the General Setup Section of the config is where you'll find powermanagement. It looks like this;

 

 

I say N (no to apm)

CONFIG_APM is not set



# ACPI Support

#

CONFIG_ACPI=y

# CONFIG_ACPI_HT_ONLY is not set

CONFIG_ACPI_BOOT=y

CONFIG_ACPI_BUS=y

CONFIG_ACPI_INTERPRETER=y

CONFIG_ACPI_EC=y

CONFIG_ACPI_POWER=y

CONFIG_ACPI_PCI=y

CONFIG_ACPI_SLEEP=y

CONFIG_ACPI_SYSTEM=y

CONFIG_ACPI_AC is not set

CONFIG_ACPI_BATTERY is not set

CONFIG_ACPI_BUTTON=y

CONFIG_ACPI_FAN is not set

CONFIG_ACPI_PROCESSOR=y

CONFIG_ACPI_THERMAL is not set

CONFIG_ACPI_TOSHIBA is not set

# CONFIG_ACPI_DEBUG is not set

# CONFIG_ACPI_TWEAKED_DSDT is not set

 

Works for me. Acpi works alongside apm in the kernel as well but you run the risk of apm being loaded first. Whichever is loaded first, is used, but you should tell the kernel through the bootloader;

 

acpi=on

 

I say N to thermal, fan, ect...because they're not available on this MoBo :roll: If you have it, say Y.

The safe way would be to say M for

CONFIG_ACPI_PCI=y

CONFIG_ACPI_SLEEP=y

CONFIG_ACPI_AC is not set

CONFIG_ACPI_BATTERY is not set

CONFIG_ACPI_BUTTON=y

CONFIG_ACPI_FAN is not set

CONFIG_ACPI_PROCESSOR=y

CONFIG_ACPI_THERMAL is not set

so if you have probs you can unload the mods.

You see, it's the other way around for me. If I enable ACPI I'm not able to shutdown. If I enable APM however, no problem to shutdown. I guess you'll have to compile two kernels and see which one is working with your MoBo .. hehe :wink:

Be faster to look at the default .config from the kernel-sources of the current kernel. :wink:

In case anyone is interested - I needed to enable APM.

 

This now works - woo hoo :-)
