libxrandr2 6.8.2-10.4 (ia64 binary) in ubuntu hoary

 libXrandr provides an X Window System client interface to the root window
 resizing, rotation, and reflection ("R and R") extension to the X protocol.
 .
 As with all X protocol extensions, support for the extension is required in
 the X server for client programs using its functionality to work as expected.
 The X.Org X server does not yet support the rotation aspects of this extension.
