x-window-system-core 4.3.0.dfsg.1-6ubuntu25 (i386 binary) in ubuntu warty

X Window System core components
 This metapackage provides the essential components for a standalone
 workstation running the X Window System. It provides the X libraries, an X
 server (except on the S/390 architecture), a set of fonts, and a group of
 basic X clients and utilities.
 .
 Higher level metapackages, such as those for desktop environments, can
 depend on this package and simplify their dependencies.
 .
 It should be noted that a package providing x-window-manager and a package
 providing x-terminal-emulator should also be installed to ensure a
 comfortable X experience.
