Hewlett-Packard is in the process of transitioning to a standard
user environment. Two user environments are shipped with HP-UX 10.20:
HP VUE and HP CDE (Common Desktop Environment). Starting with HP-UX
10.20, HP CDE will be the default user environment. HP VUE will
still be available with HP-UX 10.20, but will not be available in
future HP-UX releases. See the Common Desktop Environment
User's Guide for more information on HP CDE.
From a 3D graphics point of view, the change in user environments
should have no effect.
