As needed you can save set the power scheme by clicking on the button "Save as". If in the future the settings will go astray, you can always restore them, and no need to reconfigure every setting.
After that, you can go to the preferences on the tab "screen Saver" in the component window "Screen" (the way the call was explained in the first step). If you don't want the display there is a screen saver after a period of inactivity of the computer, that is, always display the desktop, using the drop-down list, select group "screen Saver" set to "(None)".
In this mode, there is no need to set additional parameters for time interval, so just save the new settings with "Apply" button and close the window "Properties: the Screen".
