I have Mdk 10.1 running on a laptop machine. Everything is working well with one minor exception. I run a little dock app under WindowMaker which tells me how much battery I have left, charge time, etc. Under the stock 2.6.8.1-12mdk kernel which came with 10.1 originally, it worked fine (as the apm module loaded up at boot). After updating to the 2.6.8.1-24mdk stock kernel, it doesn't.

[root@r2d2: /home/rcs]$ wmapm
No APM support in kernel

Interestingly, I can't seem to FIND an apm module in /lib/modules (or anywhere else) since updating....if it were compiled into the kernel, the app should work. Here's a search for apm* on the system.

[root@r2d2: /home/rcs]$ findr apm*
/usr/share/man/man8/apmd.8.bz2
/usr/share/man/man1/apmsleep.1.bz2
/usr/share/man/man1/apm.1.bz2
/usr/share/doc/apmd-3.1.0
/usr/bin/apmsleep
/usr/bin/apm
/usr/lib/win32/apmpg4v1.apl
/usr/lib/win32/apmpg4v1.dll
/usr/sbin/apmd
/usr/src/linux-2.6.8.1-24mdk/arch/i386/kernel/apm.c
/usr/src/linux-2.6.8.1-24mdk/include/asm-i386/mach-default/apm.h
/usr/src/linux-2.6.8.1-24mdk/include/linux/apm_bios.h
/usr/X11R6/lib/modules/drivers/apm_drv.o
/usr/X11R6/man/man4/apm.4x.bz2
/usr/include/asm/mach-default/apm.h
/usr/include/linux/apm_bios.h
/etc/rc.d/init.d/apmd

There appear to be source and header files there, but no compiled modules.
I'm sure that I'm missing something here (either between my brain and the keyboard, or the module is actually missing). Does anyone have apm support working with this kernel?

Thanks....Bob

AFAIK APM support has been rolled into the kernel under 2.6...

Check your /etc/lilo.conf file and make sure that you don't have something which reads...

apm=off

or

acpi=off

You didn't state WHICH LAPTOP you are using...

No problem....here's the GRUB menu file. It's a Dell Inspiron 8100 (P-III, 1GHz). As I said, APM worked with the previous stock kernel, (2.6.8.1-12mdk), but not this one.

WOW!

You have all of that on a LAPTOP?!?

I'm amazed.

Anyway, so ok, no ACPI on your laptop, it definitely needs APM...

You may have run into something specific to .24.

I'm having the same problem with a IBM Thinkpad R32. It was working out of the box with my MD10.0 but the battery monitor disappeared after an update to 10.1 kernel 2.6.8.1-12. Same message when typing apmd: "No APM support in kernel". I do have acpi and acpid and those where activated. apmd was also checked to start at boot but was stopped, probably because of the missing support in the kernel.
Is there a (easy) way to update the kernel to support apmd?
