Lm-sensors?

[JokersLoose]

Hey All,

I see that Lm-sensors is installed but I can't find it. I want something that will show me the fan speed, cup temp, etc. Is this a good one? Or what?

Thanks,
James

Re: Lm-sensors?

You first need to configure lm-sensors with this guide; then, you can either check your sensors by running the command "sensors" from a terminal, or by installing one of the many frontend applications - such as ksensors.

Re: Lm-sensors?

OK.. I am working on doing the configure with the guide. I am a bit confused though. I get too sensors-detect, answer Yes to all the questions. So it tells me

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

#----cut here----
# Chip drivers
# no driver for SMSC LPC47M172 Super IO Fan Sensors yet
#----cut here----

Then asks

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

So I tell it Yes.

Then, run /etc/init.d/module-init-tools

Now I run this as sudo. It brings me back to a command line.

Here's where it confuses me. It says:

To make the sensors modules behave correctly, add these lines to
/etc/modprobe.d/local and run update-modules:

#----cut here----
# I2C module options
alias char-major-89 i2c-dev
#----cut here----
#************************************************* *******************************

So I

sudo kate /etc/modprobe.d/local

But there isn't anything in this file. So I read down and it says

4. In this example, we add the modules in reverse order (order is critical!) in "/etc/modules".

#************************************************* ***********************
# /etc/modules: kernel modules to load at boot time.
#
# This file should contain the names of kernel modules that are
# to be loaded at boot time, one per line. Comments begin with
# a "#", and everything on the line after them are ignored.

psmouse
mousedev
ide-cd
ide-disk
ide-generic
lp

#For lm-sensors, i2c modules
it87
i2c-viapro
i2c-isa

#end of file!
#************************************************* ****************

And

4. 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.

Now "alias char-major-89 i2c-dev is listed in /etc/modprobe.d/aliases file. Now it does look different in my file that what is listed here

alias char-major-89-* i2c_dev

So it says "Nothing to do here" So I move to step 5 which says

5.Now load the modules manually using modprobe and update the dependencies.

So I

sudo modprobe i2c-sensor

And get

FATAL: Module i2c_sensor not found.

So I guess I missed something in step 4. Where it is telling me to add things. So what did I miss?

Thanks,
James

Re: Lm-sensors?

I honestly don't know that it is still required to build that "makedev.sh" script -- that guide is from 2004. After installing lm-sensors, I run the

sudo sensors-detect

script and it seems to work pretty well. It is not picking up the fan speeds on my CPU and case, but I suspect that is more to do with running new hardware than any shortcoming in lm-sensors. It picks up my CPU speed(s) and temps, GPU temp, hard drive temps (after I installed hddtemp), memory and swap usage, and so forth.

So, I would try running sudo sensors-detect command and see how close you come to "close enough". At the end of the script, it asks you whether you want it to make the entries in /etc/modules, you need to type "yes" since the default is "No".

Here's their current information:

http://www.lm-sensors.org/



EDIT: Also if you open the file /etc/sensors.conf, and start reading at the top, there's pretty good information before it gets into the board-specific settings.

Re: Lm-sensors?

As dibl told: Install, sensors-detect (Yes), use...


After i installed lm-sensors:

sudo sensors-detect

and

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

#----cut here----
# I2C adapter drivers
i2c-nforce2
# Chip drivers
asb100
#----cut here----

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

Answering - yes.

Reading sensor outputs:

:~$ sensors

Weird readings:

I have Asus A7N8X-E and sensors.conf /1/ tells:

# Most Asus boards have temperatures settled like that:
label temp1 "M/B Temp"
label temp2 "CPU Temp"
# However, some boards have them swapped (A7N8X Deluxe rev.2,
# A7N8X-E Deluxe rev.2, CUV4X):
# label temp1 "CPU Temp"
# label temp2 "M/B Temp"

=> To me M/B Temp is CPU Temp (with default configuration file).

/1/
sensors reads /etc/sensors.conf
sensors.conf = Sensors configuration file used by 'libsensors'

Re: Lm-sensors?

Thanks for all the replys so far

So I followed the link given http://www.lm-sensors.org/ and did the "sudo sensors-detect" Went through the list telling it "YES" each time it asked me too. Now in on the web page it says

At the end, sensors-detect should output following:

Driver `w83627ehf' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `Winbond W83627EHF/EHG Super IO Sensors' (confidence: 9)

Now mine looked a bit different

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

Driver `to-be-written' (should be inserted):
 Detects correctly:
 * ISA bus, address 0xc00
  Chip `SMSC LPC47M172 Super IO Fan Sensors' (confidence: 9)

Now because mine says 'to-be-written' does this mean no modules got written? Or what?

Next it says

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

So I "enter"

Then

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

#----cut here----
# Chip drivers
# no driver for SMSC LPC47M172 Super IO Fan Sensors yet
#----cut here----


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

So again "yes" Brings me back to the command line. So I

james@DeskTop:~$ sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.
james@DeskTop:~$

When I told it Yes to add the lines shouldn't it have loaded them for me? If not what do I do in order to load them.

Thanks,
Jame

Re: Lm-sensors?

Once you complete the "sensors-detect" session, you have to run the command:

sudo /etc/init.d/module-init-tools

You should be good to go after that.

[JokersLoose]

Re: Lm-sensors?

K I "think" it's not loading the kernel modules cause when I run "sudo /etc/init.d/module-init-tools" I get

 * Loading kernel modules...                           
* Loading manual drivers...                       [ OK ]

After that I run "sensors" and I get

No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Now when it tells me "Loading kernel modules..." and there isn't an [ OK ] after it, that means it didn't load them, right?

Thanks,
James

Re: Lm-sensors?

I think this means you are suffering from "new hardware syndrome":

# no driver for SMSC LPC47M172 Super IO Fan Sensors yet

Here's what mine says when I get to that stage of sensors-detect:

#----cut here----
# I2C adapter drivers
# modprobe unknown adapter ivtv i2c driver #0
# 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
coretemp
#----cut here----

Which is only slightly better than your result -- as you can see my new stuff doesn't get a lot of support either.

Re: Lm-sensors?

Darn. Not that it's a big deal. I just got a used system at a pawn shop and the fans on it are very noisy so thought I would run a system stat for a bit and make sure nothing is over heating and such.

Thanks,
James
