1-LXQT

Introduction

LXQt developed from popular components of LXDE and Razor Qt project, LXQt is a free, open-source, lightweight, and fast desktop environment for Linux and BSD distributions.It comes with several great and well-known features, borrowed from the LXDE desktop such as low system resource utilization and elegant and clean user interfaces.

One of its distinguished properties is the high level of customization to meet desktop usability needs. The default desktop environment on Knoppix, Lubuntu, and a few other less-known Linux distributions has been the default desktop environment.

NoteLXQt was initially supposed to become the successor of LXDE, however, as of now, both desktop environments will keep coexisting for the meantime and importantly, more development activity is being directed towards LXQt than LXDE.

The Display manager often referred as login manager is a graphical user interface you see when the boot process completes. It is responsible for loading the login Linux and then the desktop environment once you enter the credentials. 

We will talk about some of the popular Display Managers :

(4)SDDM : Simple Desktop Display Manager

SDDM became the default display manager from KDE5 replacing kdm and comes by default with systems that run KDE like Kubuntu.
