The Appearance preference tool lets you configure various aspects of how your desktop looks.
|GTK+ Theme Style|
This tab controls the visual appearance of the toolkit (Gtk+) controls, such as buttons and menus. You can switch between themes by selecting them in the list.
To install new themes, download a package from your distribution or from theme sites like xfce-look.org. When you download a theme tarball from a website, you can install it by dropping the file from the file manager in the list of styles.
This tab controls the visual appearance of icons that visible in e.g. the panel, on the desktop, in the file manager and menus. You can choose a new icon theme by selecting a theme in the list.
Also here you can install new icon themes by dropping an icon tarball in the list or install a new theme using the distributions' package management.
GTK+ has an utility to pack all the icon theme icons in a single cache file. This single file can me memory-mapped to this avoids a lot of disk seek overhead when loading icons and the file is shared between multiple applications, so the overall memory consumption is reduced as well.
For this to work each icon theme directory containing a
index.theme file, should also have an
icon-theme.cache. Distributions will most likely generate this when installing a theme package, but for custom theme you'll have to create it yourself.
To generate a cache file for an icon-theme running the following command in a terminal emulator:
More information can be found in the gtk-update-icon-cache reference manual.
The font selector button shows the name of the font and its point size. The name is also shown in bold, italic, or regular type.
To change the font, click the font selector button. The font picker dialog opens. Select the font family, style, and point size from the lists. The preview area shows your current choice. Click OK to accept the change and update the desktop.
xfconf-query -c xsettings -p /Xft/Lcdfilter -n -t string -s lcddefault
In case you want to override the DPI (dots per inch) value calculated by the X-server, you can select the checkbox and use the spin box to specify the resolution to use when your screen renders fonts. Most of the time it is not required to modify the calculated DPI, but in some cases a high DPI results in sharper fonts.
