This is the UI from the first JCS node.  The System menu icon at the top left had been clicked and from the resulting drop-down menu, Preferences has been clicked and from the resulting drop-down menu, Screensaver has been selected.
The Screensaver Preferences dialog box is displayed.  On the left-hand side is a list of screensaver themes and to the right of this list is a window showing the theme.  It is blank.
Below is a slider bar labelled Regard the computer as idle after: and the slider is positioned at 5 minutes.
Below are two check boxes labelled Activate screensaver when computer is idle, and Lock screen when screensaver is active (which is greyed-out).
Neither check box is checked.
At the bottom of the dialog box are three buttons labelled, Help, Power Management, and Close.
