CPU Frequency Scaling Monitor Manual
CPU Frequency Scaling Monitor shows the current clock speed of the CPU and provides an interface to change the clock speed if the CPU supports it.

The CPU Frequency Scaling Monitor provides a convenient way to monitor the CPU Frequency Scaling for each CPU.
To add CPU Frequency Scaling Monitor to a panel, perform the following steps:
Right-click on the panel.
Choose Add to Panel.
Scroll down the list of items in the Add to Panel dialog, then select CPU Frequency Scaling Monitor.
Click Add.
Unfortunately, CPU frequency scaling can currently only be monitored on Linux machines that have support in the kernel. It can however, support the several generations of frequency scaling interfaces in the kernel.
When there is no CPU frequency scaling support in the system, the CPU Frequency Scaling Monitor only displays the current CPU frequency.
When CPU frequency scaling is supported in the system, the CPU Frequency Scaling Monitor displays the CPU icon with a progress bar. The state of the progress bar represents the current CPU frequency with respect to the maximum frequency.
By default, the CPU Frequency Scaling Monitor displays the current CPU frequency as a value in Hertz (the standard measure of frequency), but can be configured to display a percentage instead. For more information on how to configure CPU Frequency Scaling Monitor see Asetukset.
Each instance of CPU Frequency Scaling Monitor can monitor only one CPU. You must start an instance of CPU Frequency Scaling Monitor for each CPU that you want to monitor if you are in a multiprocessor (SMP) system.

Understanding the Icons
The CPU Frequency Scaling Monitor has a series of icons that graphically represent the current scaling level of the processor you are monitoring. They are:
Kuvake	Kuvaus
100% Power	The CPU is running at, or close to, 100% throughput
75% Power	The CPU is running at, or close to, 75% throughput
50% Power	The CPU is running at, or close to, 50% throughput
25% Power	The CPU is running at, or close to, 25% throughput

Frequency and Governor Selector
The Frequency Selector functionality may not be available on your MATE Desktop by default. Please consult your system administrator, vendor documentation, or the documentation that came with this software.
To set the CPU frequency, (left-)click on the monitor and a menu will be shown. This menu will offer you a list of available frequencies and/or frequency governors for your machine.
You can choose whether you want to show available frequencies or governors in the Preferences. See Asetukset for more information.

To configure the CPU Frequency Scaling Monitor, right-click on the applet, then choose Preferences from the popup menu.
The Preferences dialog contains the following components:

The Monitored CPU option will only appear on multiprocessor (SMP) systems.
Show in Mode 	 Use this drop-down list to select the mode in which you want to display the applet. Available modes are: Graphic, Text and both (Graphic and Text)
Show CPU frequency as frequency 	 Select this option to display the current CPU frequency.
Show frequency units 	 Select this option to display or not the frequency units in the frequency mode.
Show CPU frequency as percentage 	 Select this option to display the current CPU frequency as a percentage.
Show menu 	 This option allows you to choose how much information is shown in the frequency selector dropdown (see Frequency and Governor Selector). You can select to display Frequencies, Governors or both Frequencies and Governors.
