My fan and temperature sensor dont get detected!!

_UnPrEdictAbLe_ · 08-14-2004, 07:03 AM

Hi,

I am using FC2 with 2.6.7-1.494.2.2 kernel. My motherboard is Intel 865 with P4 2.8 Ghz(HT).

Linux does not detect my fans and temperature sensors. Yes. Windows Xp is showing everything. What can I do to fix it ??

PS : I removed windows, so I need help, as I am LEARNING to do things the LINUX way.

What are you using? The latest version of lm_sensors?

Do you have the correct I2C modules for your chipset compiled in or loaded?

_UnPrEdictAbLe_ · 08-14-2004, 07:46 AM

Hi,

Well this time I didnt compile my kernel...I am using the precompiled one from FC2....that too becoz there is some network problem and I am unable to download the sourcecode...just tell me some commands to know for sure whether I have theright software. My FC2 is COMPLETELY up2date. Also tell me any place to configure them...etc... GKrellM does not detect any sensors!!

I can send outputs of those commands in the next post if required....

What do you get when you run "sensors" at the command prompt?

_UnPrEdictAbLe_ · 08-14-2004, 01:11 PM

Code:

[root@unpredictable anurag]# sensors
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and done
'modprobe i2c_sensor'!
For older kernels, make sure you have done 'modprobe i2c-proc'!

I tried modprobe i2c_sensor which completed without errors. What is sysfs?? How to mount it ? and does it get mounted automaticallly?

This is how my /etc/fstab looks.......

david_ross · 08-14-2004, 03:35 PM

You can mount sysfs with:
mkdir /sys
mount -t sysfs sysfs /sys

Then try running sensors again.

Hi, I came to know that sysfs was already mounted....tell me something new...!!

david_ross · 08-15-2004, 08:12 AM

perhaps you have had another version of libsensors before.

As root try running:
ldconfig

Then:
sensors

_UnPrEdictAbLe_ · 08-15-2004, 08:23 AM

No change......ldconfig finished without messages.........and then its the same output from sensors..

Btw i didnt even touch the version of sensors.......i have just installed fedora core 2 and didnt fiddle any system files.......

david_ross · 08-15-2004, 08:51 AM

This is pretty odd. What version of lm_sensors do you have:
sensors -v

Is i2c_sensor still loaded?
lsmod | grep i2c

_UnPrEdictAbLe_ · 08-15-2004, 09:01 AM

Code:

[anurag@unpredictable anurag]$ sensors -v
sensors version 2.8.6

Well , i2c module is NOT loaded....i did modprobe i2c_sensors......but that does not make my sensors working...

wht to do??/

unpredictable

david_ross · 08-15-2004, 09:21 AM

Do you still get exactly the same error message or are you getting a "No sensors found!" error?

_UnPrEdictAbLe_ · 08-16-2004, 09:33 PM

There is the same message all the time I do it....no change at all..

Neither modprobe nor anything else works......(shud i do "rm -rf * in /"

)

I guess it shud work for a Intel PC atleast..I guess thts wht they make most software for, in Linux.

Help me please. I removed windows. Before tht in Windows, the Intel Motherboard CD, installed all fans, etc. and they worked fine.

unpredictable

PS:Why is the word "Newbie" under my name. How can I change it?

mdg · 08-17-2004, 04:20 AM

Backing up to the beginning, did you run "sensors-detect" for lm_sensors to pick up your specific sensors? Maybe you did, I just didn't see it mentioned in your posts.

edit: you will be "newbie" until you've made a certain number of posts (I think 30)
