Enabling APMD Kernel Support

mackid97140 · 09-14-2003, 10:00 PM

I have an ibook laptop with mandrake linux installed on it. I need to enable apmd kernel support so i can put my computer to sleep. Does anyone know how to do this? I have alreadyt tried the make menuconfig, but i didn't see anything related to apmd. Also i need to know which kernel i need to modify and where it is located. I would prefer some kind of step by step info. Thanks.

When you do "make menuconfig", APM is under power management, which is under one of the first few choices. Kernels aren't modified, they are made from scratch. You should go through everything in menuconfig to make sure you don't leave out anything important in your new kernel. The Kernel-HOWTO at www.tldp.org will help.

if you make and compile your own kernel. Where do you put it so it is intigrated into the system? Do I just leave it in the /usr/src/RPM/ dir? or do i put it somewhere else. As well, last time i tried to compile a kernel, it didn't have a power management section. Is there a spacific kernel i should download?

- Download kernel 2.4.22 or 2.6.0-test2
- You should take the big file (i.e. linux-2.4.22.tar.bz2 ) inside /usr/src and uncompress it there, so you get a directory /usr/src/linux-*
- You use this directory as the temporary one for the process of building the kernel, but afterwards, the kernel is stored on /boot.

This is expailned in the Kernel-Howto:
http://www.ibiblio.org/pub/Linux/doc...nel-HOWTO.html
The kernel sources should be in the /usr/src directory. They are either in the the /usr/src/linux directory, or/usr/src/linux is a link to the folder. The Howto expalins how to install. After compiling your kernel, copy it to the /boot directory, and put an entry for it in your lilo.conf or grub.conf. For lilo, run lilo to apply the changes. There is an easier way to configure instead of make menuconfig called make xconfig.
