Configure lm-sensors

Ubuntu 10.04.1 includes lm-sensors 3.1.2 pre-installed. To verify the lm-sensors version, type the following:

> sensors -v
sensors version 3.1.2 with libsensors version 3.1.2

lm-sensors needs to be configured using sensors-detect before it can be used. sensors-detect is an interactive script for detecting hardware sensor chips. Run the following:

> sudo sensors-detect

Following sensors-detect, reboot your system, or use the following command to load the necessary kernel modules:

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

To verify that lm-sensors is operating properly, use the sensors command. Example output is shown below.
