From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Do I have to manually install PPD?
PPD comes default on most distros (I can at least confirm for Debian, Ubuntu and Fedora on the GNOME variant). I am not sure about KDE variants but they should support it too even if it's not pre-installed.
You can check if it's running with the following command:
$ powerprofilesctl
However as the 0.20 release which supports p-state just released recently most fixed point release distros won't have the newer version. In this case you would need to update it manually.
I am running Debian testing and it has the new version while stable does not.

You shouldn't use
sudo
to runpowerprofilesctl
Good point, edited!
