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? <div class=""><div class=""><br class=""></div><div class=""> Barry</div><div class=""><br class=""><div class=""><br class=""></div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Apr 24, 2022, at 7:34 AM, Flavio Riche <<a href="mailto:flavioriche@gmail.com" class="">flavioriche@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="gmail_default" style="font-family: verdana, sans-serif;">Hi,<br class=""></div><div class="gmail_quote"><div dir="ltr" class=""><div style="font-family: verdana, sans-serif;" class=""><br class=""></div><div style="font-family: verdana, sans-serif;" class="">I am new to petsc.
