I continue configuring and tweaking my ubuntu 7.04 Feisty Fawn on my Compaq presario 1500US.
Yesterday I configured the lm-sensors package in order to install a desklet or an application to see the current motherboard temperature. Because this laptop has a tendency to overheat! (see my other post :
Notebook overheat problem or Frying Eggs on Presario 1500)
First of all I launched Synaptic and searched "lm-sensors" and installed the package without problem.
(another option is to run in a terminal : sudo apt-get install lm-sensors)
Then I Ran the command :
sudo sensors-detect
and I obtained the following text :
ubuntu@horus:~$ sudo sensors-detect

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...
Sorry, no known PCI bus adapters found.
We will now try to load each adapter module in turn.
If you have undetectable or unsupported adapters, you can have them
scanned by manually loading the modules before running this script.
To continue, we need module `i2c-dev' to be loaded.
Do you want to load `i2c-dev' now? (YES/no): yes
Module loaded successfully.
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.
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!
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 LM78-J' 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
Probing for `Winbond W83627HF' at 0x290... No
Probing for `Silicon Integrated Systems SIS5595'... No
Probing for `VIA VT82C686 Integrated Sensors'... No
Probing for `VIA VT8231 Integrated Sensors'... No
Probing for `AMD K8 thermal sensors'... No
Probing for `IPMI BMC KCS' at 0xca0... 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
Trying family `ITE'... Yes

Sorry, no sensors were detected.
Either your sensors are not supported, or they are connected to an
I2C or SMBus adapter that is not supported. See doc/FAQ,
doc/lm_sensors-FAQ.html or http://www.lm-sensors.org/wiki/FAQ
(FAQ #4.24.3) for further information.
If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.
So, basically the sensors package didn't detect the sensors.
I read an installation instruction and ran the commands :
sudo gedit makedev.sh
Copy the next lines :
#!/bin/bash
# Here you can set several defaults.
# The number of devices to create (max: 256)
NUMBER=32
# The owner and group of the devices
OUSER=root
OGROUP=root
# The mode of the devices
MODE=600
# This script doesn't need to be run if devfs is used
if [ -r /proc/mounts ] ; then
if grep -q "/dev devfs" /proc/mounts ; then
echo "You do not need to run this script as your system uses devfs."
exit;
fi
fi
i=0;
while [ $i -lt $NUMBER ] ; do
echo /dev/i2c-$i
mknod -m $MODE /dev/i2c-$i c 89 $i exit
chown "$OUSER:$OGROUP" /dev/i2c-$i exit
i=$[$i + 1]
done
#end of file
Then :
sudo chmod +x makedev.sh
sudo ./makedev.sh
Afterwards I ran again sensors-detect but nothing changed... then I remembered that in my M$ Windows I used the motherboard monitor and later the speedfan so I booted M$ Windows and obtained the Speedfan output :
Win9x:NO 64Bit:NO GiveIO:YES SpeedFan:YES
I/O properly initialized

After that I found out the chip/sensor for my laptop an Intel 82801CAM ICH3 with an ADM1031. So I checked the www.lm-sensors.org and found that that chip/sensor is supported.
After searching and trying many things I finally found the script "unhide_ICH_SMBus" that show my chip/sensor :
You can download it from :
unhide_ICH_SMBus
Just in case here is the script (you can cut and paste using the gedit) :

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `adm1031' (should be inserted):
Detects correctly:
* Bus `SMBus I801 adapter at 1200'
Busdriver `i2c-i801', I2C address 0x2c
Chip `Analog Devices ADM1031' (confidence: 7)
Driver `eeprom' (should be inserted):
Detects correctly:
* Bus `SMBus I801 adapter at 1200'
Busdriver `i2c-i801', I2C address 0x50
Chip `SPD EEPROM' (confidence: 8)
* Bus `SMBus I801 adapter at 1200'
Busdriver `i2c-i801', I2C address 0x51
Chip `SPD EEPROM' (confidence: 8)
EEPROMs are *NOT* sensors! They are data storage chips commonly
found on memory modules (SPD), in monitors (EDID), or in some
laptops, for example.
I will now generate the commands needed to load the required modules.
Just press ENTER to continue:
To make the sensors modules behave correctly, add these lines to
/etc/modules:
#----cut here----
# I2C adapter drivers
i2c-i801
# Chip drivers
adm1031
eeprom
#----cut here----
Do you want to add these lines to /etc/modules automatically? (yes/NO)
I selected "Yes".
Then in order to test it I ran the commands :
root@horus:/home/ubuntu# sudo modprobe i2c-i801
Password:
root@horus:/home/ubuntu# sudo modprobe adm1031
Password:
root@horus:/home/ubuntu# sudo modprobe eeprom

I checked the /etc/modules file and all was correct. So I restarted Ubuntu and after booting I ran :
sudo sensors
But only got "No sensors detected".
To make the sensors work I had to run the unhide_ICH_SMBus first. In order to run the command in every boot I edited the file /etc/init.d/rc.local:
sudo gedit /etc/init.d/rc.local
Then I added the line calling unhide_ICH_SMBus first :
#! /bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin
[ -f /etc/default/rcS ] && . /etc/default/rcS
. /lib/lsb/init-functions
do_start() {
if [ -x /etc/rc.local ]; then
log_begin_msg "Running local boot scripts (/etc/rc.local)"
/etc/rc.local
log_end_msg $?
/home/ubuntu/unhide_ICH_SMBus
fi
}
case "$1" in
start)
do_start
;;
restart|reload|force-reload)
echo "Error: argument '$1' not supported" >&2
exit 3
;;
stop)
;;
*)
echo "Usage: $0 start|stop" >&2
exit 3
;;
esac
Afterwards I restarted Ubuntu and this time the sensors worked!
I decided to install a gdesklet to see the mother/cpu temperature in the desktop, unfortunately after trying every gDesklet that show sensors/temperature I gave up... none of them worked!!!
Finally I found the application that I wanted :
You can download the .deb package for Ubuntu Feisty here :
computertemp_0.9.6.1-0ubuntu1_all.deb
After installed with a simple double-click I right clicked in the task-bar and select "Add to panel" then browsed to
"System and Hardware" and selected "Computer temperature monitor".
Then the temperature reading appeared in the task bar :
