  When xgdisplay starts up, it needs at least 12 (11 vector colors + the
highlight color) free colors in the default color map.  If it can't get
these 12 colors, it gives up.  If you are running other applications that
are color intensive, they will hog up a majority of the colors in the
color map.  Exiting these applications will free up the colors in the
color map and xgdisplay should be able to start up.  You can run the
program 'xcmap' to look at your current default color map.
