The following assumes that you have at least a Raspberry Pi 3B+ or
newer with the latest stable version of Raspberry Pi OS (or Raspbian in
some cases) installed.

                   [Installation and Setup]


In a terminal/console run the following to install what you need:

    sudo apt install xserver-xorg xfce4 xfce4-goodies
    
Set the default desktop environment by running the following in a 
terminal/console:

    sudo update-alternatives --config x-session-manager
    
When prompted, select 'startxfce4'.

Next, to make sure that your default window-manager is 'xfwm4', run the
following in a terminal/console:

    sudo update-alternatives --config x-window-manager

If you want a login screen, run the following in a terminal/console to 
change the default display-manager to lightdm:

    sudo dpkg-reconfigure lightdm
    
However, and this is just my personal opinion, if you are decent enough
with the command-line on a system like the Raspberry Pi, you may be
better-off having it boot straight into the console and then run 
'startx' whenever you need a graphical interface. It is a few extra 
steps, but it should help your RPi last longer.

You should then reboot the Raspberry Pi; you can also do this in a
terminal/console using:

    sudo reboot

If at anypoint the desktop environment crashes, not that I expect it to,
but given how limited RAM can be on certain models, you never know, you
can start XFCE again by running either of the following in the console:

    sudo startxfce4
    
    or...
    
    sudo startx
    
We can run 'sudo startx' and have it start XFCE because of the changes
made in regards to the previously mentioned "x-window-manager" step.

------------------------------------------------------------------------

By the way, if Network Manager is not working, try running the following
in a terminal/console and then reboot:

    sudo systemctl enable NetworkManager

Also, the applet in the panel that corresponds to the Network Manager
as called 'nm-applet' if for some reason you need to use the
'Session and Startup' to have it running at login.

If Network Manager is not installed, run:

    sudo apt install network-manager network-manager-gnome
