Como decía ahí abajo, me ha dado por intentar instalar de nuevo el lm-sensors. Esta vez, al contrario que la anterior, me ha avisado de que no era un paquete firmado, o confiable, y necesitaba mi expreso consentimiento (un Sí con acento y todo) para instalarlo. Y me he arriesgado. Probablemente si me viera algún experto en seguridad me cortaría el cuello por no comprobar nada y fiarme de estas cosas….

El caso es que después como root he lanzado el famoso sensors-detect que intenta detectar qué sensores tienes en tu sistema. Anteriormente lo único que obtenía era un no sensors found, con un P4 2.8 Ghz, 512 DDR y placa Abit BH7.

root@ubuntu:/home/elsamu# sensors-detect

This program will help you determine which I2C/SMBus modules you need to
load to use lm_sensors most effectively. You need to have i2c and
lm_sensors installed before running this program.
Also, you need to be `root’, or at least have access to the /dev/i2c-*
files, for most things.
If you have patched your kernel and have some drivers built in, you can
safely answer NO if asked to load some modules. In this case, things may
seem a bit confusing, but they will still work.

It is generally safe and recommended to accept the default answers to all
questions, unless you know what you’re doing.

We can start with probing for (PCI) I2C or SMBus adapters.
You do not need any special privileges for this.
Do you want to probe now? (YES/no): YES
Probing for PCI bus adapters…
Use driver `i2c-i801′ for device 00:1f.3: Intel 82801DB ICH4
Probe succesfully concluded.

We will now try to load each adapter module in turn.
Load `i2c-i801′ (say NO if built into your kernel)? (YES/no): YES
Module loaded succesfully.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.

To continue, we need module `i2c-dev’ to be loaded.
If it is built-in into your kernel, you can safely skip this.
i2c-dev is not loaded. Do you want to load it now? (YES/no): YES
Module loaded succesfully.

We are now going to do the adapter probings. Some adapters may hang halfway
through; we can’t really help that. Also, some chips will be double detected;
we choose the one with the highest confidence value in that case.
If you found that the adapter hung after probing a certain address, you can
specify that address to remain unprobed. That often
includes address 0×69 (clock chip).

Next adapter: SMBus I801 adapter at 0500
Do you want to scan it? (YES/no/selectively): YES
Client found at address 0×08
Client found at address 0×44
Probing for `Maxim MAX6633/MAX6634/MAX6635′… Failed!
Client found at address 0×50
Probing for `SPD EEPROM’… Success!
(confidence 8, driver `eeprom’)
Probing for `DDC monitor’… Failed!
Probing for `Maxim MAX6900′… Failed!
Client found at address 0×69

Some chips are also accessible through the ISA bus. ISA probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan the ISA bus? (YES/no): YES
Probing for `National Semiconductor LM78′
Trying address 0×0290… Failed!
Probing for `National Semiconductor LM78-J’

Trying address 0×0ca8… Failed!

Some Super I/O chips may also contain sensors. Super I/O probes are
typically a bit more dangerous, as we have to write to I/O ports to do
this. This is usually safe though.

Do you want to scan for Super I/O sensors? (YES/no): YEs

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `eeprom’ (should be inserted):
Detects correctly:
* Bus `SMBus I801 adapter at 0500′
Busdriver `i2c-i801′, I2C address 0×50
Chip `SPD EEPROM’ (confidence: 8 )

Driver `w83781d’ (may not be inserted):
Misdetects:
* ISA bus address 0×0290 (Busdriver `i2c-isa’)
Chip `Winbond W83627HF’ (confidence: 8 )

Driver `w83627hf’ (should be inserted):
Detects correctly:
* ISA bus address 0×0290 (Busdriver `i2c-isa’)
Chip `Winbond W83627HF Super IO Sensors’ (confidence: 9)

Durante la detección, el programa nos preguntará si deseamos buscar sensores en determinados buses… como podeis ver, en mi caso, la mayoría de los tests fallaron, tan sólo reconociendo el driver para el Intel 82801DB ICH4. Al parecer Abit no proporciona documentación sobre los chips que monta y esto perjudica el desarrollo de programas como este.

Al final, incluso se nos dice los módulos que debemos cargar al inicio y si deseamos que el programa nos las añada por nosotros al /etc/modules:

I will now generate the commands needed to load the I2C modules.
Sometimes, a chip is available both through the ISA bus and an I2C bus.
ISA bus access is faster, but you need to load an additional driver module
for it. If you have the choice, do you want to use the ISA bus or the
I2C/SMBus (ISA/smbus)? smbus

To make the sensors modules behave correctly, add these lines to
/etc/modules:

#—-cut here—-
# I2C adapter drivers
i2c-i801
i2c-isa
# I2C chip drivers
eeprom
w83627hf
#—-cut here—-

Do you want to add these lines to /etc/modules automatically? (yes/NO)NO

Y terminó la detección. Lo proximo es arrancar el sistema y comprobar que los sensores funcionan
