Ubuntu temperature monitor

Background

I am trying to figure out how to monitor temperature on my Ubuntu system, and I found this thread:

So I started installing the packages recommended in response #5, but response #4 may be good, too.

Synopsis
$ sudo apt-get install lm-sensors hddtemp
$ sudo sensors-detect
$ sudo /etc/init.d/kmod start
[ ok ] Starting kmod (via systemctl): kmod.service.
$ sensors

Adapter: Virtual device
temp1:        +54.0°C  (crit = +120.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0:  +53.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:         +52.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:         +51.0°C  (high = +100.0°C, crit = +100.0°C)
