It's supported by the plugin, but it doesn't work.
If the plugin has the frequency switching controls, but they don't do
anything please report a bug (if not already reported).
To http://www.debian.org/Bugs/ and/or https://bugzilla.xfce.org/ ?

Hi :)
I didn't file a bugreport, since it looks like it should be able to set
the governor, but the menus should simply show available governors.
Instead I wrote a script that e.g. can be used for a launcher. Each time
you click the launcher, the governor for the CPU frequency scaling will
be toggled from one to another.
I think we had the same idea, but I thought of a small pyGtk
notification area gui. Basically a kind of standalone clone of the gnome
plugin...
I set up un gitorious:
https://gitorious.org/gcputray
(or simply get the tar.gz of the current master:
https://gitorious.org/gcputray/gcputray/archive-tarball/master )
Only problem is that you have to run it as root. Actually any suggestion
on how to wisely set it up for user would be welcome
Lorenzo.
E.g. right click the Xfce panel> Panel> Add New Items...> Mark
"Launcher"> + Add> Close>
Right click the launcher icon> Move it, if wanted> Right click again>
Properties> Tab: General> Click the icon for "Add a new empty
item" (or later "Edit the currently selected item")>
Name: CPUfreq-GOVtoggle
Comment: Toggle CPU frequency scaling governor
Command: cpufreq-govtoggle
Icon: Application icons/xfce4-cpufrq-plugin or
Application icons/gnome-cpu-frequency-applet
Create or Save
You might use the freq monitoring plugin without an icon and move the
launcher, showing the icon only, in front of it.
Have fun,
Ralf
This is the script, read the comments how to install it:
#!/bin/sh
# Install and uninstall
# First copy the shell script to /usr/local/bin
# To initialize everything that's needed to use this script as user run
# su -lc "sh /usr/local/bin/cpufreq-govtoggle --init"
# To undo changes as user run
# su -lc "sh /usr/local/bin/cpufreq-govtoggle --undo"
# Usage
# E.g. by a panel launcher, as user run
# cpufreq-govtoggle
