The Red Hat Linux distribution comes with a variety of window managers such as mwm and twm which support overlapping windows, popup menus, point-and-click or click-to-type input models, title bars, nice icons (and an icon manager for those who don't like separate icon windows). Full desktop environments such as Gnome and Kde go further with integration of applications in an X environment. Font names Collections of characters for displaying text and symbols in X are known as fonts. A font typically contains images that share a common appearance and look nice together (for example, a single size, boldness, slantedness, and character set). Similarly, collections of fonts that are based on a common type face, the variations are usually called roman, bold, italic (or oblique), and bold italic (or bold oblique), are called families. Fonts come in various sizes. The X server supports scalable fonts, meaning it is possible to create a font of arbitrary size from a single source for the font. The server supports scaling from outline fonts and bitmap fonts. Scaling from outline fonts usually produces significantly better results on large point sizes than scaling from bitmap fonts. An X server can obtain fonts from individual files stored in directories in the file system, or from one or more font servers, or from a mixtures of directories and font servers.

Window managers
The layout of windows on the screen is controlled by special programs called
window
managers
. Although many window managers will honor geometry specifications as
given, others may choose to ignore them (requiring the user to explicitly draw the
window's region on the screen with the pointer, for example).
Since window managers are regular (albeit complex) client programs, a variety of
different user interfaces can be built.
The Red Hat Linux distribution comes with a
variety of window managers such as
mwm
and
twm
which support overlapping
windows, popup menus, point-and-click or click-to-type input models, title bars, nice
icons (and an icon manager for those who don't like separate icon windows).
Full
desktop environments such as Gnome and Kde go further with integration of applications
in an X environment.
Font names
Collections of characters for displaying text and symbols in X are known as
fonts
. A font
typically contains images that share a common appearance and look nice together (for
example, a single size, boldness, slantedness, and character set). Similarly, collections of
fonts that are based on a common type face, the variations are usually called roman, bold,
italic (or oblique), and bold italic (or bold oblique), are called
families
.
Fonts come in various sizes. The X server supports scalable fonts, meaning it is possible
to create a font of arbitrary size from a single source for the font. The server supports
scaling from outline fonts and bitmap fonts. Scaling from outline fonts usually produces
significantly better results on large point sizes than scaling from bitmap fonts.
An X server can obtain fonts from individual files stored in directories in the file system,
or from one or more font servers, or from a mixtures of directories and font servers. The
