and uses the DRM API to list available display "connectors" (HDMI, DisplayPort) and their supported video modes (resolution, refresh rate). Learning Goal:
Developing software for the Linux graphics subsystem requires moving past standard window abstractions and managing hardware resources directly. By completing these projects—rendering via raw DRM nodes, spinning up an isolated Wayland compositor environment, and configuring dma-buf pipelines—you will gain a practical understanding of how Linux processes pixels from code to the screen.

: For older X11 setups, configure the system to accept TCP transport loops ( DISPLAY=:1 ). For modern Wayland instances, use tools like wayland-tracker or capture UNIX sockets using specific kernel tracing facilities.
