Take a look at the toshset and toshutils packages available in the debian
repositories. I have used toshset with success to turn the fan of an old
Tecra 8100 on (command (as root): toshset -fan on), but I was using ubuntu
7.04 then. In debian etch, I get this message:

required kernel toshiba support not enabled.

I haven't had the time to investigate how to enable it yet.

Hope this helps, anyway.

My fan works fine by itself now (Thinkpad X31), but I recall needing to use
the command

echo 3 > /proc/acpi/[SOMEPATH]/fan

on Etch as root to turn my fan off when it became stuck on full after
suspending. I could also use values from 0-3 to set it to different speeds.

I now use Lenny and the fan file has a slightly different path and more
detailed content, e.g.:

status: enabled
speed: 0
level: auto

However, now I find I can't write to this file directly, even as root, who
supposedly has write permissions! This I don't get.

Anyhow, if you can find your /proc/acpi/.../fan file, see what's in it and
change the value of the fan speed (if you can write to it), that may work.

HTH,

John

Well, on my machine, fan is an empty directory.
The ls command gives:

what he described is a thinkpad feature, the "native" fan acpi interface is
mostly broken, or not supported by the bios.

Like someone suggested already, look for the toshiba tools packages in
debian.

Well, I tried the toshiba tools but this is the output I receive:
msb01:/usr/src# toshset -fan on
required kernel toshiba support not enabled.

So it seems that I have to recompile the kernel with CONFIG_ACPI and
CONFIG_ACPI_TOSHIBA flags enabled.

Anyone knows if there ere stock debial kernel with these flags enabled?

Regards
Mirto

That's interesting. "apt-cache show toshset" says it doesn't rely on
kernel support.

Your comment pointed me in a new crazy way.
In the link http://www.flurble.org/computers/toshset.pl I read:
=====================

There are two modules for Toshiba laptop support in recent linux kernels.

* *toshiba*, found at
o Processor type and features -> Toshiba laptop sopport,
o CONFIG_TOSHIBA,
o drivers/char/toshiba
* *toshiba_acpi*, found at
o Power management -> ACPI -> Toshiba laptop extras,
o CONFIG_TOSHIBA_ACPI,
o drivers/acpi/toshiba_acpi

If you load *toshiba*, and run toshset ...

$ sudo toshset -q
machine id: 0xfcff BIOS version: 1.40 SCI version: 7.148
toshset version: 1.71 Toshiba Model: Portege M100/M300 Tecra M2/A2/A3
HCI/SCI access mode: kernel
* toshset: this computer is not supported*

=====================

On my machine I read:
---------------------------------------------------------
msb01:~# toshset -q
required kernel toshiba support not enabled.
---------------------------------------------------------

So I had to setup the environment to compile a kernel gettin the sources
from the debian package linux-source-2.6.22.tar.bz2
But inspecting the .config I see that are already enabled:

Toshiba Laptop support (TOSHIBA)

This adds a driver to safely access the System Management Mode of
the CPU on Toshiba portables with a genuine Toshiba BIOS. It does
not work on models with a Phoenix BIOS. The System Management Mode
is used to set the BIOS and power saving options on Toshiba portables.

and

Toshiba Laptop Extras (ACPI_TOSHIBA)

This driver adds support for access to certain system settings
on "legacy free" Toshiba laptops. These laptops can be recognized by
their lack of a BIOS setup menu and APM support.

So recompiling kernel in not an option: toshiba support in the kernel is
already enabled.

I think that the toshset doesn't relay on kernel because the stock
kernel has already tohiba support enabled.

But now I'm completely lost.
I'm using debian on this machine since when etch was the testing version
and I never had thermal problems.

It is only from this summer that I started to have thermal problems. I
thinked that the weather was too hot; but now the weather is cold and I
still have thermal problems.

On my Satellite P20 there is no fan control in BIOS and I'm not able to
use toshset to force the fan on.

What can I do?


Thanks
Mirto

Below the old message.

Now I'm trying to load the toshiba modules.
What happen is that the module exists but modprobe says that it not exists.
The modprobe and ls output:

msb01:/usr/src# modprobe toshiba
FATAL: Error inserting toshiba
(/lib/modules/2.6.22-2-686/kernel/drivers/char/toshiba.ko): No such device
msb01:/usr/src# ls -l
/lib/modules/2.6.22-2-686/kernel/drivers/char/|grep tos
-rw-r--r-- 1 root root 8935 2007-08-31 05:39 toshiba.ko

What can I do?

Thanks
Mirto

iirc toshiba.ko is for old models only.

Fantastic!
I have a Toshiba Satellite P30-130 model number PSP30E-20E019IT that is
trying to burn because I cannot control the fan.

Every module and utility I found for Toshiba laptops doesn't work saying
that my kernel doesn't support toshiba utilities.

Please, can someone tell me what can I do to avoid burning my laptop?
(the CMOS menu haven't any fan control)

Thanks

did you already take a look at:
http://memebeam.org/toys/ToshibaAcpiDriver

if this doesn't help you.. i suggest you should ask the linux-acpi ML for
help with your laptop.
AND.. make sure you tried a _new_ kernel before.

Whops! I'm using 2.6.22+10 (I'm on Lenny). Do you mean I have to use
2.6.22+11 from SID?
