In comes Gnome 3, out goes my beloved (out of necessity) CPU frequency applet. It seems Gnome 3 does not do applets, at least not yet. And I have a couple of miscreant laptops that love to overheat under load. One Lenovo is actually almost unusable unless I throttle back the CPU before extended heavy loads like a massive apt-get upgrade.
 clued me in to a command-line option to the applet in the cpufreqd package. After installing cpufreqd one must first uncomment the following lines in /etc/cpufreqd.conf:
which basically enables the command-line tools. Now
will list your options, and
is how you choose your CPU speed, and
displays the available frequencies, and
shows the current frequency in effect. And now I can install Gnome 3 on these handicapped machines....
