About this..

Swappiness

This setting requires root privilege, and a reboot for changes to have effect

Abstract: The default Ubuntu setting is no good for desktop/multimedia production use. 10 is a good value. But, the user could be allowed to change it to something else too. What are good values here, and what are min-max values?

Actions:

• Set a new value for swappiness in a custom file at /etc/sysctl.d/*

Graphical control:

• Slider to set swappiness from 0-?

CPU governor

Abstract: In order to change the cpu governor on the fly, we'll need access to do so.

Actions:

• ?

Graphical Control:

• Display available governors as radio buttons.
