Ubuntu Hardy 8.04 LTS Desktop + AppleSMC + lm-sensors

[kamimark]

Hey guys,
I know this subject is being discussed a million times. Since I have been googling about it for half a week and found loads of posts. But since most of the posts are relatively old (2005-2007) I have a few questions.

First my goal. Increase the fan speed of my iMac 2006 (early) cause the Video Card is crashing.

Now according to my "research" i have found that there are several ways to do this.
One is using the applesmc module and configure the minimum fan speed to a higher value (same as smcFanControl app in MAC OSX).
However the folder where the file should exist for the minimum fan speed doesn't exist. No folder named applesmc or applesmc.XXX exist in /sys/devices/platform/

Also tried adding a line to /etc/sysctl.conf
devices.platform.applesmc.fan0_minimum_speed=5000

I also checked in the modules and applesmc seems to be loaded automatically.

Also tried to load applesmc module manually and I got some error which I don't remember. :)

Now the lm-sensors part.
After downloading all the related packages and doing a sensors-detect it detects only the Intel Core Duo temperature sensor.
So using sensors after reboot i can only see the temperatures.

The following info is from my unreliable memory :)
sensors-detect also detects something like "Trying SMC family - Yes. Unknown 0x00".

and dmesg outputs something like:
applesmc: wait status failed: c != 19

Also read some stuff about compiling a mac specific kernel but those posts were kind of old. I assume that Hardy generic can handle this right?

How can I achieve my goal? (installing MacOSX or Windows XP is not the answer I'm looking for :P)

Please help me. I wasted too much time on this...

Hi,

If the folder applesmc doesn't show up in /sys/devices/plateform, try shutting down the computer completely, and then boot again.
If you boot into OSX and then reboot into linux, OSX messes with applesmc.
If you never had this folder, then I don't know.
But once you have /sys/devices/plateform/applesmc.768/fan1_min it's very easy to put in this file the fan speed you want.

But since the kernel update 2.6.24-21, I don't find this file anymore, but my fan is @ 4000 rpm (the speed I chose).




Also tried adding a line to /etc/sysctl.conf
devices.platform.applesmc.fan0_minimum_speed=5000
Never heard about that.




Now the lm-sensors part.
After downloading all the related packages and doing a sensors-detect it detects only the Intel Core Duo temperature sensor.
So using sensors after reboot i can only see the temperatures.

For lm-sensors, go on the website and download the latest perl script. then run it, it should detect more things.
and read this also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/235119



and dmesg outputs something like:
applesmc: wait status failed: c != 19
I have these messages too. Don't know how to stop them.



I hope I helped you :)

This means applesmc is not loaded, or something went wrong. Check


lsmod | grep applesmc


If it is not there, do


sudo modprobe applesmc


No need to reboot the machine. If it fails, please report the error. Everything else you wrote depends on this error.

Regarding the sensor quality, you should get the updated applesmc from this thread: http://ubuntuforums.org/showthread.php?t=924096&highlight=applesmc

Make sure you are running the 2.6.24-19 kernel when testing (2.6.24-21 no supported yet).

sensors-detect gives this as before

Trying family `SMSC'... Yes
Found unknown chip with ID 0x0b00

If the folder applesmc doesn't show up in /sys/devices/plateform, try shutting down the computer completely, and then boot again.
If you boot into OSX and then reboot into linux, OSX messes with applesmc.
Did it still same.
I dont have OSX anymore :)


Went to
http://ubuntuforums.org/showthread.p...light=applesmc
updated the thing
now it seemed a bit better
since
sudo modprobe applesmc doesn't give an error

lsmod | grep applesmc shows it inside :)

/sys/devices/platform/applesmc.768/ appeared.

changed the value and it worked.

But what's the deal with the lm-sensors?
I can't use it at all?

I can't make much out of that error, which is supposed to set things up. However, did you try to run skip that and just run


sensors

1. Please see the "Before you post" link in my signature to properly identify your iMac.
2. The applesmc module is really only for Macbooks.

That's all that works on my iMac too.

You can still compile a custom kernel. That really hasn't changed. You can do that for any computer. You really don't need to though.

There is a config for iMac in applesmc too, now. However, there are presumably several models unsupported so far. I you like, you could try running the scan-smc.sh script from this post:

http://ubuntuforums.org/showthread.php?t=924096&highlight=applesmc&page=2

and report the output here.

I will try that too. It has been awhile since I tried.

EDIT: Actually, it seems to work fairly well now for me...

I managed to miss the attachment, but reading through it I see your model is not covered. Could you please provide the


sudo dmidecode | grep 'Product Name:'

and I'll add it for testing. One should not have to live with missing sensors anymore :-)

The version # is in my signature ;)

If you need more info than that, I will have to get it later since I am currently out of town and don't have access.

Bless you, cyberdork :-)

Ok, iMac5 it is. I attached the module source file here if you want to compile it yourself. Otherwise, with knowledge about which kernel version you run and which architecture, I can post a binary here for testing.

[kosumi68]

Once there, running the test script from this post http://ubuntuforums.org/showpost.php?p=5998563&postcount=53 ought to settle things.

I noticed your machine has a light sensor. Is it used for anything in particular on your machine?

will do. I didn't know there was a light-sensor. I haven't noticed that it does anything... (OSX or otherwise).

Linux Grover-Ubuntu 2.6.27-7-generic #1 SMP Fri Oct 17 22:24:30 UTC 2008 x86_64 GNU/LinuxI think I figured out how to build and load the module though. log from test script attached. Light and LEDs are "not available".

Temps look good now though.
