GUI

Introduction

HelenOS starts into a simple graphical user interface, provided a usable graphical output device is found (otherwise it will start into a text console). You can move windows around, close them, resize, etc. using your mouse. For debugging purposes, there is a set of keyboard shortcuts availble (see below).

On startup you are presented with a console window (you can type commands there), a launcher window and a barber pole window.
