xorg binary package in Ubuntu Lunar s390x

 This metapackage provides the components for a standalone
 workstation running the X Window System. It provides the X libraries, an X
 server, 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 should also
 be installed to ensure a comfortable X experience.
