HOW TO: Install and configure lm-sensors

[Glaucous]

I've now been trying for a couple of hours to get this program working, I even compiled 3.1.1 from their site without any luck.
I followed the last post on the previous page.

sensors-detect:

# sensors-detect revision 5729 (2009-06-02 15:51:29 +0200)
# System: Gigabyte Technology Co., Ltd. GA-MA790X-UD3P

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): yes
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD K10 thermal sensors... Success!
(driver `to-be-written')
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal and voltage sensors... No

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): yes
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No
Trying family `ITE'... Yes
Found `ITE IT8720F Super IO Sensors' Success!
(address 0x228, driver `it87')
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Fintek'... No
Trying family `ITE'... No

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes
Probing for `IPMI BMC KCS' at 0xca0... No
Probing for `IPMI BMC SMIC' at 0xca8... No

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (yes/NO): yes
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): yes
Using driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc SB600 SMBus
Module i2c-dev loaded successfully.

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

Driver `it87':
* ISA bus, address 0x228
Chip `ITE IT8720F Super IO Sensors' (confidence: 9)

Driver `to-be-written':
* Chip `AMD K10 thermal sensors' (confidence: 9)

Note: there is no driver for AMD K10 thermal sensors yet.
Check http://www.lm-sensors.org/wiki/Devices for updates.

Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes
Copy prog/init/lm_sensors.init to /etc/init.d/lm_sensors
for initialization at boot time.
You should now start the lm_sensors service to load the required
kernel modules.

Unloading i2c-dev... OK

I opened /etc/modules, and tried inserting the following (changed each reboot when it didn't work):

-
Driver `it87':
* ISA bus, address 0x228
Chip `ITE IT8720F Super IO Sensors' (confidence: 9)

-
Chip `ITE IT8720F Super IO Sensors' (confidence: 9)

-
Chip `ITE IT8720F Super IO Sensors'

-
`ITE IT8720F Super IO Sensors

Without any luck, still says when I run sensors:
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Edit: NOW i realized that I was supposed to add "it87", which makes sense.

My /etc/modules looks like this :

I think yours should be something like :

#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

it87

it87 is probably a sensor on your motherboard and should give you CPU temps too.

Exactly what I did, sorry for not clarifying that. Fanspeed is working good, the only problem now is to get AMD K10 working, for my CPU.
Since I'm right now sitting on Wubi, I have no problem playing around, right now I'm testing stuff in order to install Ubuntu correctly later on.

I installed Linux kernel 2.6.33 RC4, which seems to be working okay. People said that AMD K10 was supposed to be working here, but it's not so far, might have to change something in lm sensors as well.

Edit: At last, got it working! A small problem though, how do I restart fancontrol? Right now I'm tweaking the config file, would be easier if I could restart it.

[confusion_music]

I've only just got a whole new setup up and running last night, so I've not tested this yet, but I believe the following thread may have the answers for K10 sensors.

Hi,

I'm currently running 9.04 and my fan is constantly running (Sony Vaio VGN-Z serie).
My laptop is about a year and a half old.
I upgraded this week to 9.10 but this didn't change the situation.
I tried almost everything (even fansilencer program, but this doesn't work either).

I installed lm-config and the output of sensors is:

acpitz-virtual-0
Adapter: Virtual device
temp1:       +48.0°C  (crit = +107.0°C)                  

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +37.0°C  (high = +100.0°C, crit = +100.0°C)  

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +37.0°C  (high = +100.0°C, crit = +100.0°C)

pwmconfig gives following (after sensorsdetect)

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed

The fan noise is really driving me crazy (I'm currently studying and I want SILENCE!)
I didn't had this problem about a couple of months ago.


Anyone can help?

The 1st place to go to change your is your BIOS, if your BIOS supports changing fan speeds. I haven't needed programs to change the fanspeed, so I can't help you with that. Sorry

So I followed the guide, but ran into a problem, in that I have very little displayed when I run "sensors"... see below.

candice@candice-desktop:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:       +40.0°C  (crit = +75.0°C)

Adapter: PCI adapter

candice@candice-desktop:~$ sensors-detect
You need to be root to run this script.

This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. 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.
Do you want to probe now? (YES/no): YES
Probing for PCI bus adapters...
Use driver `i2c-piix4' for device 0000:00:14.0: ATI Technologies Inc IXP SB400 SMBus Controller

We will now try to load each adapter module in turn.
Module `i2c-piix4' already loaded.
If you have undetectable or unsupported I2C/SMBus adapters, you can have
them scanned by manually loading the modules before running this script.

We are now going to do the I2C/SMBus adapter probings. Some chips may
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.

Next adapter: NVIDIA i2c adapter  (i2c-0)
Do you want to scan it? (YES/no/selectively): YES

Next adapter: NVIDIA i2c adapter  (i2c-1)
Do you want to scan it? (YES/no/selectively): YES
Client found at address 0x50
Probing for `Analog Devices ADM1033'...                     No
Probing for `Analog Devices ADM1034'...                     No
Probing for `SPD EEPROM'...                                 No
Probing for `EDID EEPROM'...                                Yes
    (confidence 8, not a hardware monitoring chip)

Next adapter: NVIDIA i2c adapter  (i2c-2)
Do you want to scan it? (YES/no/selectively): YES

Some chips are also accessible through the ISA I/O ports. We have to
write to arbitrary I/O ports to probe them. This is usually safe though.
Yes, you do have ISA I/O ports even if you do not have any ISA slots!

Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No

Probing for `IPMI BMC SMIC' at 0xca8...                     No

Some Super I/O chips may also contain sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): YES
Probing for Super-I/O at 0x2e/0x2f

    (driver `k8temp')
AMD K10 thermal sensors...                                  No
Intel Core family thermal sensor...                         No
Intel AMB FB-DIMM thermal sensor...                         No

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

Driver `k8temp' (should be inserted):
  Detects correctly:
  * Chip `AMD K8 thermal sensors' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue: 

To load everything that is needed, add this to /etc/modules:

#----cut here----
# Chip drivers
k8temp
#----cut here----

Here is my /etc/modules:

# /etc/modules: kernel modules to load at boot time.

Any ideas? Thanks!

[Scott O'Nanski]

Could you explain step 4 a bit better. It's confusing. You stated to add the modules in reverse order but from looking at your example they are not.

[Scott O'Nanski]

Okay, you said to answer "yes" to all the "YES/no" questions. Are you implying that the "yes/NO" question at the end is to be answered "NO"?

I get this bounced back to me from the terminal:

#----cut here----
# I2C adapter drivers
# modprobe unknown adapter NVIDIA i2c adapter 
# modprobe unknown adapter NVIDIA i2c adapter 
# modprobe unknown adapter NVIDIA i2c adapter

# modprobe unknown adapter NVIDIA i2c adapter 
# modprobe unknown adapter NVIDIA i2c adapter 
# Chip drivers
# no driver for Analog Devices ADT7473 yet
it87
coretemp
#----cut here----

What am I being told here, what am I to do with it?

As well, you state

I found that there was no "/etc/modprobe.d/local" and that "alias char-major-89 i2c-dev" was already listed in "/etc/modprobe.d/aliases". So, nothing to do here.

Can you explain the relevance of this statement? Following the post I don't see why this is important. It there something about this information I might want to know about?
