Why is this message seemingly being produced for every PETSc executable run? PETSc, by default, should not be doing anything with X-Windows calls unless a specific option related to X windows is used even if PETSc is compiled and linked against X windows. These test runs are not using anything related to X-Windows. Just having the X windows libraries linked into the executables should not produce such messages so why are they appearing?
