CPU frequency scaling for 12.04?
indicator-cpufreq can be found in the Software Center by searching "cpu frequency" and then clicking on the "show technical items" option:
And this is what it looks like, to compare what you were used to in 10.04:
- Note that you may need to put it in startup if you don't wish to start it manually every time -- usually it should go into Startup Applications automatically, like this:
I use indicator-cpufreq on Unity. It seems very parallel to what I use with 10.10. You can install it using
sudo apt-get install indicator-cpufreq
This what I use to set the frequency of CPU in Ubuntu 12.04.
If you want to have control of CPU frequency in Ubuntu 12.04, do this:
- open Ubuntu software center or synaptic software manager
- Install awn-settings (this is a dock)
- Now open awn settings and set to start-awn automatically
- Restart computer
- Now you must have the dock on the bottom of desktop
- Right click Dock preferences
- Go on to Applets tab.
- In the Categories section select Monitor and from right section Available Applets double click on CPU Frequency monitor to add on dock.
I did a little bit of research and found this thread on Ubuntu Forums that explains how to use cpulimit to set the maximum consumption for a particular process. It runs as a daemon that will monitor all processes.
