KGX is an acronym for the free software combination of KDE/GNU/linuX for a graphical workstation.

This term was invented as a means to market the usage of KDE on GNU/Linux platforms. These types of acronyms have been somewhat successful for other products (see LAMP), but KGX never really built any momentum.
