<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial",sans-serif">So if I follow the XOpenDisplay sequence up the stack I see xcb_connect() / _<i>xcb_open</i>_abstract( ) trying to open “/tmp/.X11-unix/X0” with protocol set to 0. On one system
it eventually calls select(), on another it uses poll() instead, so it is looking for a response. Once in a while it takes over a minute to get a response. Can anyone describe a general overview of what it is trying to open? Any idea why the select/poll
call hangs so long?<o:p></o:p></span></p>
