In this article, I will take you through the steps to install libxcb-dri3-0 package on Ubuntu 20.04 LTS. linxcb-dri3-0 is basically a set of library files needed to run a software using libxcb-dri3, the dri3 extension for the X C Binding. The XCB library provides an interface to the X Window System protocol mainly designed to replace the Xlib interface due to multiple reasons. XCB provides several advantages over Xlib interface which we will see in a short while. More can be checked on Debian Page. It is also very easy to install in almost all the linux distributions. Here we will see the steps to install libxcb-dri3-0 package on Ubuntu 20.04 LTS based systems.

Advantages of XCB Library over Xlib

• It is a small size library and hence having lower memory footprint
• It can queue up several requests at once and then wait for the response later
• It provides one-to-one mapping between interface and protocol
• It can access XCB from multiple threads without putting any explicit locking
• It can automatically generates interface from machine-parsable protocol descriptions.
