How To Install nxagent on CentOS 8
Introduction
In this tutorial we learn how to install nxagent on CentOS 8.
What is nxagent
NX is a software suite which implements very efficient compression of the X11 protocol. This increases performance when using X applications over a network, especially a slow one. nxagent is an agent providing NX transport of X sessions. The application is based on the well-known Xnest server. nxagent, like Xnest, is an X server for its own clients, and at the same time, an X client for a system’s local X server. The main scope of nxagent is to eliminate X round-trips or transform them into asynchronous replies. nxagent works together with nxproxy. nxproxy itself does not make any effort to minimize round-trips by itself, this is demanded of nxagent. Being an X server, nxagent is able to resolve all the property/atoms related requests locally, ensuring that the most common source of round-trips are nearly reduced to zero.
