HOW TO: Install and configure lm-sensors

[Miroku]

so i got to this stage after sensors-detect:

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

#----cut here----
# I2C adapter drivers
# modprobe unknown adapter NVIDIA i2c adapter 
# modprobe unknown adapter NVIDIA i2c adapter 
# modprobe unknown adapter NVIDIA i2c adapter 
# Chip drivers
# Warning: the required module smartbatt is not currently installed
# on your system. For status of 2.6 kernel ports check
# http://www.lm-sensors.org/wiki/Devices. If driver is built
# into the kernel, or unavailable, comment out the following line.
smartbatt
it87
coretemp
#----cut here----


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

i chose NO and now i need some further clarification please. thx.

[bulldog]

Better choose Yes instead,or add the lines manually.

Hi I have a Sony Vaio and the fans used to be controlled in windows so that they would slow down after startup. I was able to get the sensors and fans detected, but how do I slow down the fans? Or get them controlled depending on temperature. This is just a kitchen computer for internet surfing, so it probably doesn't need the fans to ever run this high. But right now its just so loud.

Hi andymadonna,

I wrote these in my blog to remind me of how i configure my fancontrol with the lmsensors. I hope this could help you with it.

Only a couple of sensors seems to have got detected:

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +63.0°C (crit = +100.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +67.0°C (crit = +100.0°C)



Shouldnt I have more?

[Jugix]

Nice HOWTO! Now I can seriously overclock my CPU with linux because I know core temps now. TY!

[abetterlie]

great writeup, thanks a million.
up and running and temperature sensoring in minutes.

[SR_ELPIRATA]

WOW, I was wondering why x-sensors wasnt working. Installed lm-sensors easily though steps 3 to 5 were done by the system automatically, which was pretty nice. I did all this because I wanted to get GKrellM working that specific area and it did, but after doing it noticed that I could add these sensors to my panels easily and it looks 'clean', so I dont know, I think Im going to stick with these instead of GKrellM (but Im not going to uninstall them neither).

[slick_nick]

Seems like it's gotten a lot easier to get sensors up and running since this thread was started; I don't think anyone has given a new how-to so I will. Thanks to the folks in this thread [ http://ubuntuforums.org/showthread.php?t=671015 ] I got it working quickly taking the following steps:

1. Open a terminal and do the ol' sudo apt-get install and install lm-sensors and sensors-applet.
2. After the install, run sudo sensors-detect and say Yes to everything.
3. Restart your computer.
4. Right-click the bar at the top of the screen and select Add to Panel. Find Hardware Sensors Monitor and click Add.


You can also type "sensors" into the terminal and get a readout like this:

A couple people asked this a while ago in this thread, and didn't get an answer as far as I saw, so I'll ask again: Anyone know what temp3 is?!?

[wnelson]

If you look in /etc/sensors.conf you will find all of the chip set definitions. Most temp3 are ignored. Just browse that file and find out.
