To help you navigate your work on these projects, keep this visual map of data flows in mind:
Map the allocated buffer into user space via mmap to paint pixels.
: Create a wlr_renderer to handle GPU drawing commands and a wlr_allocator to manage pixel storage structures.
: Use the Wayland protocol libraries to create a compositor that can accept a single client window and display it.
: Utilizing Wireshark to capture and analyze how graphics requests are dispatched through the system. Underlying Concepts Covered

Linux exposes graphics hardware through device nodes in /dev/dri/ . Run ls /dev/dri/ to identify your nodes:
