xorg-common 6.8.2-77.3 (amd64 binary) in ubuntu breezy

 xorg-common contains the filesystem infrastructure required for further
 installation of the X Window System in any configuration.
 .
 Those wishing an X server only (with remote font services and clients) will
 also require the xserver-common package and an X server package (most
 likely xserver-xorg).
 .
 The counterpart to the above configuration is a machine with the X libraries
 (the xlibs package), xbase-clients, a window manager, some X font packages,
 and likely many more client packages.
 .
 Those who desire a standalone X workstation (and/or are fuzzy on the concepts
 of X servers and X clients) will require both of the above sets of packages.
 For convenience, the "x-window-system" metapackage will include everything
 that is required for a standalone X workstation.
 .
 A number of terms are used to refer to the X Window System, including "X", "X
 Version 11", "X11", "X11R6", and "X11R6.8". The version of X used in Debian
 is derived from the version released by the X.Org Foundation, and is thus
 often also referred to as "X.Org". All of the preceding quoted terms are
 functionally interchangeable in an Ubuntu system.
 .
 Until recently, Ubuntu shipped an X implementation released by The XFree86
 Project, Inc. (aka "XFree86"). The X.Org implementation is derived from the
 XFree86 implementation previously shipped, and is generally considered to be
 the standard implementation by vendors and distributors.
