The author shares their journey in creating a single-file C program to open a window in Linux using the X11 protocol, bypassing xlib libraries. They explain the basics of X11 protocol, surprise at how it functions similarly to network protocols like HTTP, and how Xlib documentation can be more complex. The author simplifies the communication process with the X server by demonstrating socket connection initialization and handling responses. Additionally, they detail creating a window, mapping it on the screen, and setting up an event loop to listen for events. The post provides a hands-on experience in understanding window communication in Linux systems using Xorg for window management.
