I have tried adding that applet. It doesn't add properly, ie; no
icon, just a blank bar about 1/16 inch thick.. When I do left click
and select preferences, I can change to performance. But again, the
applet does not install properly on the panel, and does nothing when I
click on it

Please read all of my posts. I have stated that I did try starting it
from the control center, and it does not start.No feedback, nothing.

running cpufreqd from a terminal prompt just returns the prompt with no
feedback.

This directory is empty, the cpufreq and cpufreqd.conf files are located
in /etc

I am pretty sure that cpufreqd is not running. I am beginning to think it
might be easier to reinstall.

Thanks to all who replied. Will try some of these suggestions when I
get home and let you know the results.

Right click on a blank area of the menu bar. Select Add to Panel. Add the applet
called "Cpu Frequency Scaling Monitor".

Left click on the frequency icon.

Note that the Policy has four settings, Conservative, Ondemand, Performance,
and powersave.

While the policy may be set to Performance, the frequency scaling is probably
set to dynamic, aka ondemand. Unlike kpowersave, the gnome frequency scaling
monitor does not appear, to have any option to change the cpu frequency, used
for a given policy. However, it appears, that if you select the max freq shown
as possible, and it should change the frequency. I haven't tested to see if this
holds over a reboot. In my case, I've used kpowersave, to change the default
for the performance policy, from dynamic, to performance, and it appears that
the gnome applet, hasn't altered this.

Do not have kpowersave in my tray, and running gnome, and the preferences
for this are set to performance.

Darklight

do you have kpowersaved installed if so it should be to the right of the
taskbar next to the clock the icon looks like a two pin plug.

if you left click on the above icon it will tell what frequency policy you
are using if it is set to dynamic when the pc is idle it will show up
running at less than half

to get pc to run at full speed change it to performance

May or may not help. I don't recall if cpufreqd is installed by default or
not. Open the package manager and search for cpufreq. Make sure that
cpufreqd and it's 2 libcpu* packages are installed. Also check that
powernow_k8 module is installed and finds your cpu on boot.

I checked the system services in the Control Center. CPUFREQD is not
running, and will not start when I click the start button (It is set to
run on boot).

If I try the command from a terminal I get no feedback, and ps -ef|grep
cpufreqd shows the command is there.

cpufreq-selector -f doesn't seem to work either.
