libxinerama1-dbg 2:1.0.1-0ubuntu1 (amd64 binary) in ubuntu dapper

X11 Xinerama extension library (debug package)
 libXinerama provides an X Window System client interface to the XINERAMA
 extension to the X protocol.
 .
 The Xinerama (also known as panoramiX) extension allows for multiple screens
 attached to a single display to be treated as belonging together, and to give
 desktop applications a better idea of the monitor layout.
 .
 This package contains the debug versions of the library found in libxss1.
 Non-developers likely have little use for this package.
 .
