Common Desktop Environment
The Common Desktop Environment is a desktop environment for Unix and OpenVMS, based on the Motif widget toolkit. It was part of the UNIX98 Workstation Product Standard, and was long the "classic" Unix desktop associated with commercial Unix workstations. Despite being a legacy environment, it is still kept alive with support for Linux systems as well.
The base CDE system is installed through the cdesktopenvAUR package.
The cdesktopenvAUR package supplies the
dtlogin systemd service which upon starting will launch the CDE login manager.
CDE can be directly launched with
startx (install xorg-xinit):
$ export PATH=$PATH:/usr/dt/bin $ export LANG=C $ startx /usr/dt/bin/Xsession
