    Question How to suspend my Debian "etch" laptop? Where's APM?



    When I used Debian "sarge", it was easy to suspend my laptop. Now the same command does not work:

    Code:
    smeagol:/home/daan# apm -s
No APM support in kernel
smeagol:/home/daan# modprobe apm
FATAL: Error inserting apm (/lib/modules/2.6.15-1-486/kernel/arch/i386/kernel/apm.ko): No such device
smeagol:/home/daan#
    I'm not sure my 90's laptop supports ACPI, although I do get a response when I do

    Code:
    smeagol:/home/daan# acpi
     Battery 1: charging, 98%, 00:02:32 until charged
smeagol:/home/daan#
    What command should I use to see if I can use this ACPI?

    And if it doesn't work, how do I get the kernel to support APM?

    Debian kernels are built with APM support but it is disabled by default. You need to boot the kernel with the "apm=on" option if you want to enable the driver.

    debian apm

    Your old BIOS probably wont handle acpi. You should pass noacpi parameter because acpi will by default turn off apm. Good luck.

    How do I do those things?

    I've tried editing my /boot/grub/menu.lst file like this:

    Code:
    title		Debian GNU/Linux, kernel 2.6.15-1-486
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15-1-486 root=/dev/hda2 ro apm=on
initrd		/boot/initrd.img-2.6.15-1-486
savedefault
boot
    and also like this:

    Code:
    title		Debian GNU/Linux, kernel 2.6.15-1-486
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15-1-486 root=/dev/hda2 ro noacpi
initrd		/boot/initrd.img-2.6.15-1-486
savedefault
boot
    and like this:

    Code:
    title		Debian GNU/Linux, kernel 2.6.15-1-486
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15-1-486 root=/dev/hda2 ro noacpi apm=on
initrd		/boot/initrd.img-2.6.15-1-486
savedefault
boot
    but still I'm told there's no APM support in the kernel (after rebooting, apmd is installed). Also when I modpobe apm...

    Btw, when I was using Debian "sarge", I did not need apm=on to use apm.

    you might try rolling your own kernel, and making sure apm is on and apci is off

    I feared that might be needed to get APM working. Quite some work, as it would the be the first time I would be doing that.

    Still I'm very happy with my new Debian "etch". Nice new features, such as the alacarte menu editor and the latest version of gnumeric, all available through apt-get.

    Thanks for your help, Vergil and Lestoil.

    actually it isn't that bad. If you do it the debian way, everything currently enabled in the current kernel will be enabled. All you should have to do is enable apm and disable acpi.

    I've got APM now without a recompiled kernel. The correct way to disable ACPI when booting is by adding "acpi=off" in stead off "noacpi" to /boot/gub/menu.lst, like this:

    Code:
    title		Debian GNU/Linux, kernel 2.6.15-1-486
root		(hd0,1)
kernel		/boot/vmlinuz-2.6.15-1-486 root=/dev/hda2 ro acpi=off
initrd		/boot/initrd.img-2.6.15-1-486
savedefault
boot
    After loading the APM module, I can suspend and resume and I have all other nice APM features!
