How do I remove desktop environment

[Bret Busby]

Hello.

I am wondering how I can quickly, simply, and, safely, remove a desktop 
environment.

One of my computers that I am using, with an i5 CPU and only 16GB of 
RAM, had both the LXQT and the Mate desktop environments installed, due 
to concerns about the capability to run Mate, with the lesser resources 
of the computer.

Mate is the default desktop environment, and, I have been satisfactorily 
using it, with the deprecated theme that I retain and use, for a number 
of years.

At boot up, the login GUI screen offers the option of logging in to the 
LXQT desktop environment or the Mate desktop environment, showing the 
Mate desktop environment as the default one, and, I do not remember 
having logged into the LXQT desktop environment, for some years, on the 
computer.

So, I want to remove the LXQT desktop environment, if I can quickly, 
simply, and, safely, remove it, as it is redundant, and, I am not aware 
of using any of the components of that desktop environment.

So, can I quickly, simply, and, safely, remove it, and, if so, how?

Thank you in anticipation.
