I am not sure. I spawnv() X applications all the time and have no problems
openning the display. Before starting the X application I always make sure
DISPLAY is set, e.g.,

  if ( !getenv("DISPLAY") ) putenv("DISPLAY=localhost:0.0");
  spawnv(_P_DETACH,path,argv), etc...

As I reported here the other day, I am having problems with execv() in the
lastest coolview.
