Update:

   checkX  does work of course.

My problem was:
     1. I was setting the DISPLAY environment variable which X11 based clients use
        and expected checkX to use it as well.

     2. I specified the X11 server to try, incorrectly as $ checkX  127.0.0.1:0, without
        the -d option.  For some reason I had it in my head that usage was: 
         checkX [options]  <server>. 

     	Hower, checkX works when server is specified with the -d option as documented.
        E.g. $  checkX -d 127.0.0.1:0

  THanks for the input to help me find this.  My apologies for not spotting this sooner. 

Regards,

Charles Wilson
