ibm-acpi not working!

kungpow · **Joined:** Tue Feb 14, 2006 4:41 pm **Posts:** 34

I have added: "ibm-acpi" to /etc/modules. I have then restarted the computer but it only works for the first 5 minutes, then the fan goes on again permanently eventhough I have only emacs running. Any ideas on how I get the acpi module to work for more than 5 minutes? I have an IBM T40/p

You really ought to give more details about the distro you're using, the kernel, whether ibm-acpi is used as a module, etc...

As far as I know, the fan on my A31 was never controllable at all under linux. You could try changing the thermal trippoints in ACPI, but I never thought it was worth the bother.

I use Ubuntu, kernel 2.6.12-10-386. A I wrote I have added: "ibm-acpi" to /etc/modules, and made sure it is running by typing:

johs@ubuntu:~$ lsmod | grep -i ibm
ibm_acpi 17908 0
johs@ubuntu:~$

Do you have

options ibm_acpi experimental=1

in /etc/modules.d/ibm_acpi.modprobe ?

If not, add it like this:

echo "options ibm_acpi experimental=1" >> /etc/modules.d/ibm_acpi.modprobe

Then reboot, or do:

rmmod ibm_acpi
modprobe ibm_acpi

Check if you get an output with both:

cat /proc/acpi/ibm/thermal
and
cat /proc/acpi/ibm/fan

Finally, this is just the "interface" to the thermal sensors and the fan. The fan won't stop just like this. You need a script running that checks the sensors and sets the fan speed. You can find that here:

Ok I now have this:

Code:

johs@ubuntu:~$ cat /etc/modules
# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

lp
mousedev
psmouse
ibm_acpi
johs@ubuntu:~$

and this in: /etc/modprobe.d/

Code:

options ibm_acpi hotkey=enable,0xff9f,experimental=1

The I have rebooted but afterwards I get:

Code:

johs@ubuntu:~$ cat /proc/acpi/ibm/thermal
cat: /proc/acpi/ibm/thermal: No such file or directory

johs@ubuntu:~$ cat /proc/acpi/ibm/fan
cat: /proc/acpi/ibm/fan: No such file or directory
johs@ubuntu:~$

And the fan starts to run again after a few minutes, permanently .

What does "dmesg | grep acpi" and "modprobe ibm_acpi" give?

You have v0.8 of ibm_acpi which isn't good enough. That is probably the module that was included with your kernel. You'll need version 0.11 for the experimental option. You can download this version here: http://ibm-acpi.sourceforge.net/

The README file http://ibm-acpi.sourceforge.net/README has the instructions how to compile and install the baby.

When this is done and "dmesg | grep acpi" after a reboot shows that you now actually run the 0.11 version, I'd suggest to read http://thinkwiki.org/wiki/ACPI_fan_control_script to learn how to go on from there.

I just get this error when I try to make it:

root@ubuntu:/home/johs/apps/ibm-acpi-0.11/ibm-acpi-0.11# make
make -C /lib/modules/2.6.12-10-386/build SUBDIRS=/home/johs/apps/ibm-acpi-0.11/ibm-acpi-0.11 modules
make: *** /lib/modules/2.6.12-10-386/build: No such file or directory. Stop.
make: *** [default] Error 2
root@ubuntu:/home/johs/apps/ibm-acpi-0.11/ibm-acpi-0.11#

I have read the readme but it only says that I need to run

make
make install

But it seems that something is missing...

Whats does "ls -la /lib/modules/" and "uname -a" give?

Though I am not sure, I think the problem is caused by the fact that your kernel-headers/source does not match your kernel version.

I don't know if there is an easy way to fix it. Personally, I would download the kernel sources and compile and install a custom kernel at this point. This way I'd know exactly what I have. I'm using kernel 2.6.12, while I had issues with newer kernels.
You would not need to do any modifications to the kernel config (just make sure ibm_acpi is set to M, not to Y) and after compilation, installation and reboot, I think the compilation of ibm_acpi should work.

Here's on HOWTO: https://wiki.ubuntu.com/KernelHowto
If you use this, you need to read and appy the "Using an existing configuration" section. It shows how to use your existing kernel configuration as the base for the configuration of your new kernel. Unfortunetly, this section is not in the HOWTO where you need it, but appended below.

I would like to revive an old thread here, since I am having these problems now..

I am trying to install ibm_acpi on my X60, under Ubuntu 6.10 running under VMware 5.5.3, and have a basic understanding of how to use Linux. All I need from this is the ability to toggle the Thinklight so that I can use the Gaim-thinklight plugin to notify me of incoming instant messages.

I have ran 'make' and 'make install' sucessfully on ibm_acpi version 0.11, but cannot get past 'modprobe ibm_acpi'. Here is my output:

sparta@thinkpad:/lib/modules/2.6.17-11-generic/acpi$ ls
ibm_acpi.ko
sparta@thinkpad:/lib/modules/2.6.17-11-generic/acpi$ sudo modprobe ibm_acpi
FATAL: Error inserting ibm_acpi (/lib/modules/2.6.17-11-generic/acpi/ibm_acpi.ko): No such device

If there is any other info I can give that will enable anyone to help me, just let me know. Also, if there is any howto or forum threads that can solve my issues, I wouldn't mind just being pointed there either. I have already tried searching through this forum, Ubuntu's forum, as well as Googling for how to install ibm_acpi.

This is your problem. You have to be running on an actual thinkpad, not a virtual machine. VMWare emulates a specific hardware set, and IBM has nothing to do with it.

sorry to bringing back to life this obsolete thread , but do you know how to forceloading some modules to prevent :
cat: /proc/acpi/ibm/thermal: No such file or directory

Some of my logs at :

First use

Code:

lsmod | grep acpi

to check it hasn't loaded.

Code:

modprobe x

to manually insert.

I think you're problem might actually be to do with the move from /proc to /sys/class
