X Server
X Server is the open-source windows system commonly used in Linux OS. It permits and allows network interfacing as well. The caveat however, is that it is more complex compared to its competitor: Wayland. However, it is the most stable and compatible across most Linux distributions. This section guides you on how to operate X Server.
Installation
X server comes in different styling implementations called "desktop manager" (DM). Hence, installing X really depends on which desktop manager is required for a desktop environment (DE).
For LXQt DE, either SDDM or LightDM is used. Their installations command are as following:
$ apt install sddm -y
$ apt install lightdm -y
In worst case scenario, one can still use xdm (but highly not recommended):
$ apt install xdm -y
