To report a bug or make a suggestion regarding the &applet; applet or this manual, follow the directions in the MATE Feedback Page. CPU Frequency Scaling Monitor

The &applet; provides a convenient way to monitor the CPU Frequency Scaling for each CPU. To add &applet; 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 &applet;. 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 &applet; only displays the current CPU frequency. When CPU frequency scaling is supported in the system, the &applet; 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 &applet; 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 &applet; see . Each instance of &applet; can monitor only one CPU. You must start an instance of &applet; for each CPU that you want to monitor if you are in a multiprocessor (SMP) system. The &applet; has a series of icons that graphically represent the current scaling level of the processor you are monitoring. They are: Icon Description 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 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 for more information.

To configure the &applet;, 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 ). You can select to display Frequencies, Governors or both Frequencies and Governors.
