The Common Desktop Environment (CDE) is a desktop environment for Unix and OpenVMS, based on the Motif widget toolkit. It was part of the UNIX 98 Workstation Product Standard, and was long the "classic" Unix desktop associated with commercial Unix workstations.
After a long history as proprietary software, CDE was released as free software on 6 August 2012, under the GNU Lesser General Public License, version 2 or later. Since its release as free software, CDE has been ported to Linux and BSD derivatives.
Hewlett-Packard, IBM, SunSoft, and USL announced CDE in June 1993 as a joint development within the Common Open Software Environment (COSE) initiative. Each development group contributed its own technology to CDE:
After its release, HP endorsed CDE as the new standard desktop for Unix, and provided documentation and software for migrating HP VUE customizations to CDE.
In March 1994 CDE became the responsibility of the "new OSF", a merger of the Open Software Foundation and Unix International; in September 1995, the merger of Motif and CDE into a single project, CDE/Motif, was announced. OSF became part of the newly formed Open Group in 1996.
In February 1997, the Open Group released their last major version of CDE, version 2.1.
Red Hat Linux was the only Linux distribution to which proprietary CDE was ported. In 1997, Red Hat began offering a version of CDE licensed from TriTeal Corporation. In 1998, Xi Graphics, a company specializing in the X Windowing System, offered a version of CDE bundled with Red Hat Linux, called Xi Graphics maXimum cde/OS. These were phased out, and Red Hat moved to the GNOME desktop.
