sudo aptitude install cpufrequtils
sudo aptitude install indicator-cpufreq
then run
indicator-cpufreq
An applet will appear in the system tray, providing two categories of
information. (I only see these options in KDE when I right click on the
applet):
CPU speed - mine show:
2.60 GHz
1.90 GHz
1.40 GHz
0.80 GHz
The second category will show the cpu frequency governor presently set on the
system. One of the following will be selected. Mine shows 'ondemand' already
selected:
Conservative
Ondemand
Powersave
Performance
I tested this on Toutatis. I haven't changed the defaults. If you read up on
which cpu governor will suit your needs the best, it might be better to
select the governor you wish to run at boot, although I haven't looked into
how to do that yet myself.
Hope this helps
