Visual User Environment

Visual User Environment is a discontinued desktop environment developed by Hewlett-Packard, intended for use on Unix workstations. VUE is based on the Motif widget toolkit and targets the X Window System.
VUE is a precursor to Common Desktop Environment, which was also based on Motif.

History

Work began on VUE in 1988 at Apollo Computer for use with Domain/OS, as an alternative to Apollo's standard DM and wmgr.
Shortly later, HP acquired Apollo, where they released the first version of VUE for Domain/OS, and then went on to modify VUE for use with HP-UX.

VUE 1.0 – Released with Domain/OS SR10.4
VUE 1.1
VUE 2.0 – Released for HP-UX
VUE 2.0.1
VUE 3.0 – Released with HP-UX 9.0 in 1992

According to an article published in the Hewlett-Packard Journal, the look and feel of HP-VUE was used when developing the Common Desktop Environment :
After its release, HP endorsed CDE as the new standard desktop for Unix, and provided documentation and software for migrating VUE customizations to CDE.
