CPU frequency scaling in Ubuntu

I've managed to activate CPU frequency scaling of my SI1520's Core 2 Duo processor in Ubuntu Feisty.
Everything passes through the CPU Frequency Scaling Monitor Gnome applet, which must be reconfigured to enable manual CPU frequency scaling.

The shell command to do this is:

$ sudo dpkg-reconfigure gnome-applets

You will have to answer “Yes” to the question regarding setting the suid of the cpufreq-selector executable. Now you can left click on the CPU Frequency Monitor Applet and choose the CPU frequency and/or operative mode (Conservative, Ondemand, Powersave, Performance).

Ubuntu Tip: Disable Synaptics touchpad while typing

Finally!!
If you are like me, and can't help but involuntarily touch the touchpad while typing on the keyboard, here is the solution (thanks to ubuntugeek.com):

1. Open a terminal and type: sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_synbackup
2. Type gksudo gedit /etc/X11/xorg.conf
3. Look for the section called: Section “InputDevice” / Identifier “Synaptics Touchpad”
4. Just above the line that says "End Section" type this line: Option “SHMConfig” “on”
5. Save, close all the windows and restart Gnome (Ctrl-Alt-Backspace)
6. Open the sessions manager: System -> Preferences -> Sessions
7. In the Startup Programs tab click the "New" button
8. Type "Syndaemon" in the name field and "syndaemon -i 1 -d" in the command field
9. Close and restart Gnome (Ctrl-Alt-Backspace)
10. Voila!
