I am using FreeBSD 2.2.2.  When running Xwindows applications I get the
following error:

(When I don't set the display variable)

Error: Can't open display:

(When I set it to :0)

Error: Can't open display: :0

I don't know what I should set my display variable to.  I have tried setting
it to :0, unix:0, unix:0.0, as they were suggested in archived mailing list
messages.  None of them caused any different results.  Please copy all
suggestions to me at theta@gte.net. 

Thank you,
Chris
