As they say, GNU/Linux is great because you can set it up with a familiar Windows-like interface, or you can create something unusual and non-standard.
For retro enthusiasts, there's good news — making your computer resemble the good old warm tube computers from the early 90s has become even easier.
Not so Common Desktop Environment, or abbreviated as NsCDE — is a modern version of the well-known old-school CDE environment, which was long considered classic for Unix-like operating systems.
CDE or Common Desktop Environment — is a desktop environment for Unix and OpenVMS, created based on the Motif widget toolkit. For a long time, CDE was regarded as the 'classic' environment for Unix systems. CDE was proprietary software for a long time, and the source code for the popular environment from the 90s was made publicly available only in August 2012. It no longer holds any practical interest as CDE has become morally outdated in terms of its capabilities and usability.
The project is based on FVWM, enhanced with patches and extensions necessary for recreating the CDE interface. The settings and patches are written in Python and Shell.
The developers aimed to create a user-friendly retro-style desktop environment that supports modern software and technologies without causing discomfort during use. During development, generators for corresponding themes were created for Xt, Xaw, Motif, GTK2, GTK3, Qt4, and Qt5, making it possible to style almost all modern programs to resemble CDE.
