The upper part of the dialog shows the fonts selected for the application, desktop, window title, and
terminal. Click one of the buttons to open a selection dialog where you can set the font family, style,
and size.
To specify how to render fonts on your screen, select one of the following options:
• Monochrome: Renders fonts in black and white only. The edges of characters might appear
jagged in some cases because the characters are not antialiased. Antialiasing is an effect that is
applied to the edges of characters to make the characters look smoother.
• Best Shapes: Antialiases fonts where possible. Use this option for standard Cathode Ray Tube
(CRT) monitors.
• Best Contrast: Adjusts fonts to give the sharpest possible contrast and antialiases fonts so that
characters have smooth edges. This option might enhance the accessibility of the GNOME
Desktop to users with visual impairments.
• Subpixel Smoothing (LCDs): Uses techniques that exploit the shape of individual Liquid
Crystal Display (LCD) pixels to render fonts smoothly. Use this option for LCD or flat-screen
displays.
Click Details to specify further details of how to render fonts on your screen:
• Resolution (Dots Per Inch): Use the spin box to specify the resolution to use when your
screen renders fonts.
• Smoothing: Select one of the options to specify how to antialias fonts.
• Hinting: Select one of the options to specify how to apply hinting to improves the quality of
fonts at small sizes and at low screen resolutions.
• Subpixel Order: Select one of the options to specify the subpixel color order for your fonts.
Use this option for LCD or flat-screen displays.
2.2.3 Configuring the Screen Saver
A screen saver is a program that blanks the screen or displays graphics when the computer is not
used for a specified amount of time. Originally, screen savers protected monitors from having
images burned into them. Now they are used primarily for entertainment or security.
