KGX – Minimal Terminal Emulator Aims to be Core App for GNOME & Phosh

KGX is a simple and user-friendly terminal emulator for GNOME. It aims to be a “Core” app for GNOME and Phosh, graphical shell for mobile devices like Purism’s Librem 5.

Rather than replacing GNOME Terminal, it’s on target to serve casual Linux user who rarely needs a terminal to carry out simple command line tasks. Via libhandy library, the terminal adjusts nicely to small screen sizes and for touch usage.

The name KGX is the station code for King’s Cross, the London terminus of the East Coast Main Line. The app is available in Ubuntu repositories since Ubuntu 21.04, though the package version is lag behind.

The stock KGX in Ubuntu 21.10 has a semi-transparent app window and the UI looks kinda like Gnome terminal. Though it’s lightweight and has less features.
