In Gnome 2 there was panel applet that one could use to do that, however in Lubuntu there isn't one, how can i adjust it then?.

Preferably with a simple method, don't really want to directly edit any system file.

CPUFreq script

The is a lightweight script available.

Download and save with the filename "cpufreq.sh".

Now install zenity

sudo apt-get install zenity

Give the script execute permissions

cd ~/Downloads
chmod +x cpufreq.sh

When you want to change cpu-frequency run

~/Downloads/cpufreq.sh

Lubuntu Plugin

This is how Lubuntu/LXDE should work... however its been broken since 11.04. Hopefully in the near future this problem is resolved and this comment can be deleted

Right-click the panel and choose...

Click the Add button...

Add CPUFreq - this will add an icon to your desktop to change CPU frequency

Note - I dont have a PC that has scalable CPU frequencies to test this applet... let me know if it works for you

Oh, how i missed this, one thing though i can't click on the applet? to adjust anything, only a window pop ups with "remember governor.." but i can't actually change the governor, anyways, seems like this applet is not as capable as the one in gnome 2.Thanks – Uri Herrera Oct 30 '11 at 17:36
    
curious - if it is not a click - is it instead a right-click to change the frequency? Otherwise it sounds like a bug that needs to be reported. – fossfreedom♦ Oct 30 '11 at 18:53
    
Nope, right-clik brings the contextual menu, left click doesn't do anything, i searched in the LXDE forums came across 2 threads with this same issue, none of them had an answer they were dated 2009 so i don't think the LXDE guys are fixing this, i had to use a script to change the governor. – Uri Herrera Oct 30 '11 at 19:40

I found this script that looks lightweight - you just need to install the package zenity to use it - gtk-apps.org/content/show.php/… – fossfreedom♦ Oct 30 '11 at 20:28
    
That's the script i'm using :D. – Uri Herrera Oct 30 '11 at 21:41
