xutils 1:7.7+12ubuntu1 (amd64 binary) in ubuntu xenial

 xutils provides a set of utility programs shipped with the X Window System.
 Many of these programs are useful even on a system that does not have any X
 clients or X servers installed.
 .
 This package is provided for transition from earlier Debian releases, the
 programs formerly in xutils and xbase-clients having been split out in smaller
 packages.
