I think most UNIX folks use X as their desktop and then use X Terminals for command lines. If you use a basic console you are limited to the console unless you use the virtual consoles (like in Linux) where you can shift from console to console using the F(function) (or similar) keys.

However, in most X based desktops you have much more control over your command line terminals (xterms). So, if are going to do a bunch of compiling and working on a lot of different projects, having a desktop to launch X terminals makes life much easier.

On the other hand, if you are just running a server for your web, firewall, ftp, mail or other network service, then there may be little benefit to using the extra memory on your X environment.

Since you are just learning, you need to also learn the X environment, including X server and other X related utilities sooner-than-later. X is an integral part of all UNIX environments and helps teach many essentials too.

This does not mean that you should use X GUIs to change directories and play in your filesystem (like Windows Explorer); using command line utilties like find and cd to explore the filesystem is better and more efficient, IMHO. However, having many open X Terms can be very helpful if you like to multitask and do many things at once. In other words, you can be a command line guru via the X environment. That is what most people do.

SYSTEMD-GETTY-GENERATOR(8)				      systemd-getty-generator					SYSTEMD-GETTY-GENERATOR(8)

NAME

       systemd-getty-generator - Generator for enabling getty instances on the console

SYNOPSIS

       /usr/lib/systemd/system-generators/systemd-getty-generator

DESCRIPTION

       systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console /dev/console if that is
       not directed to the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer consoles, if
       execution in a virtualized environment is detected. This should ensure that the user is shown a login prompt at the right place, regardless
       of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line
       argument such as console= to get both kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt[1] for more information
       on the console= kernel parameter.

       systemd-getty-generator implements the generator specification[2].

       Further information about configuration of gettys you may find in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and
       Elsewhere)[3].
