Re: Trouble CPU frequency and battery on macbook

Hello everybody,

I got news on this problem, perhaps this will help fixing my problem. I got the speedstep working by adding some lines to the /etc/rc.local script, as described in the debian wiki for the macbook.

But, I still don't have my battery recognized. So I installed an ubuntu feisty as dual boot on my macbook since the ubuntu documentation says that the battery of the macbook is recognized without problem and without having to compile a custom kernel.
But, after installing and updating the ubuntu (I installed from the live CD) it happens to have the same behavior as on debian --> The battery is not recognized (gnome applet says no battery is present).

So, I suppose that the kernel parameters are not the cause of this; did I forgot something (a daemon, a program, a module)?

Thanks a lot

Hello List,
I recently got a new Macbook and while tryning to install debian on it I have some trouble getting the cpu frequency scalling and the battery status working.
I followed the tutorials on:

Here are the action I did exactly:
- Following these tutorials, I got a 2.6.22 kernel from kernel.org
- I pachted them with the mactel sources for this kernel version
- I recompiled the kernel using the configuration file provided by the gentoo wiki and set all cpu frequency scalling options to modules (powersave, ondemand, ...) and the default governor to userspace
- Once recompiled, I installed cpufreqd

On the Gnome desktop, the battery applet tells me that there is no battery present, as if ACPI was not configured correctly and cpu frequency scalling
applets tells me that my CPU's are running at 100% (although default governor is userspace).

CPU frequency scalling works with the command line:
cpufreq-set -c 0 -d 1GHz, so I tried to make an init script with this, but this does not seem to work. In fact, the script seems never to be executed.
To do this, I followed the tutorial on:

I thought CPU frquency and battery management were governed by the same features.
Does anybody know why I don't get my battery status to work? Did I for forgot a module in the kernel?
How come that I can't get my CPU frequency to run on minimum although userspace is set?
Finally, how come that my script is not executed although the symblic links in te different runlevel were created?

Thanks for your help.
