HOW TO: Install and configure lm-sensors

[Skatox]

It doesn't work for me in Breezy, too.

[JimmyJazz]

no work for me in breezy HP pavilion zt3000

oke: i installed lm_sensors in breezy 5.10 on a A2K Asus Motherboard. this is a nforce3 board. should also work on nforce2 ones
the sensors work. i didn't use the how-to exactly.

starting with root all commands:

$: synaptic
=> search for "lm_sensors" and install the package "wmtemp". this also
installs lm_sensors and all dependencies.

then detect your motherboard sensors with:

$: /usr/sbin/sensors-detect

type "YES" in each test. i got everything failed in "ISA" mode. so
In the end i choose "smbus". It will write some new lines in /etc/modules.

you can look in $: vim /etc/modules and see the added lines.
now you must load all of these added modules separately

$: modprobe XXXX

after that, if you type now the command $: sensors you get fine output.


my question is now... how can i change the fanspeed manually? i want to let the fanspeed rotate at a specific speed, as i know from "speedfan" in windows, where it worked. yes, not exactly the RPM, but ti change the % how fast it is rotating. ACPI is supported in my motherboard, powernow, also working and activated. which steps do i have to do for the manual control of the fanspeed?

Thanks for your helpfull notes Tschackomuizi, I used them for a MSI K8N Neo2 plat. motherboard, nforce3. I got this output from sensors:

Not exactly what I expected because I chose SMbus output over ISA in sensors-detect, and the i2c drivers are for SMbus. Still most values are from isa.
The min and max values are sometimes strange, but it is a start.

Thanks again.

I installed lm-sensors and ran sensors-detect (on breezy) and I am getting some strange results.

My setup in an Gigabit GA-71XE4 motherboard with an Athlon 1GHz processor.

Clearly there must be something wrong wth the temperatures being displayed, and I don't understand why the fans are not showing any rpm.

Has anyone got any pointers for me?

EDIT - I found that temp3 is not used for AMD processors. It does not appear in my BIOS and I have no sensor for this, hence the strange results. I have ignored this in my sensors.conf. I still have one question though, my BIOS reports fan speeds and yet lm_sensors does not, does anyone have any idea why I am not getting anything for the fans?

After I install xsensors and then ran it, why this?

rjarrrpcgp@ubuntu:~$ sudo -s
root@ubuntu:~# xsensors
Sensor 'it8712' not supported by xsensors!


Is the hardware monitoring chip really rare?

But, this is with Hoary! (I wished that they moved the lm-sensors topic to another forum)

It seems that the new versions supports it :

http://www.linuxhardware.org/xsensors/CHANGELOG

[dudus]

I've got some odd results from the sensor thing. Some values seems out f range, I think I should tweek this in the conf file. The temp3 is disabled and I can't figure out how to enable it.

When I use xsensors, it says that my chip isn't supported (it8712). My verssion of xsensors is 0.46. In the developer website I read that xsensors 0.47 supports my chip. But this verssion hasn't made into the repos yet.

Not sure If I should install the package since I don't fell confartable installing something that isn't even in the backports.

First of all, great guide! Everything works, except the version of lm_sensors that installs through apt-get is 2.9.1, and the version that contains the driver for my sensors (SMSC 47M15x/192) is 2.9.2. Therefore, when I run sensors-detect it detects everything just fine, but simply says there is no driver for my hardware. I have tried manually installing version 2.9.2, but I get nothing but errors. Is there an easier way to maybe just install the module I need for this chip even though the rest of the package is version 2.9.1? Any ideas?

-Eric

[crag277]

nevermind. I checked more carefully this time, and the driver I need doesn't exist yet. Looks like I need to wait.

[Cuppa-Chino]

hi thx for the guide, got mine to work nearly straight off the bat...

where can I mod the limits - my VCore show too high, my MOBO temp is always alarmed:

fan1:        0 RPM  (min = 135000 RPM, div = 2)
CPU Fan:     0 RPM  (min =   -1 RPM, div = 2)
fan3:     1599 RPM  (min = 84375 RPM, div = 4)
M/B Temp:    +38°C  (high =   +33°C, hyst =    +0°C)   sensor = thermistor 
CPU Temp:  +30.5°C  (high =   +80°C, hyst =   +75°C)   sensor = thermistor 
temp3:     -48.0°C  (high =   +80°C, hyst =   +75°C)   sensor = thermistor 
vid:      +1.525 V  (VRM Version 9.0)
alarms:

          Sound alarm enabled

but I am okay with for instance the MOBO temp.

also where is conf file for xsensors as my display a lot about the sensors that have 0 readings above?

thanks
