Once you have built several projects and understand the code flow, the next step is to contribute back. The Linux graphics stack is entirely open source and welcomes new contributors.
After gaining practical experience with the underlying display pipeline, you can then build projects that utilize the modern graphics APIs that define Linux's high-performance capabilities: EGL, OpenGL ES, and Vulkan.
: For each output, trigger a repaint loop. Inside the loop, clear the background and iterate over all active client surfaces, rendering them back-to-front using OpenGL or Vulkan structures provided by wlroots .

To display an image, you must find an active connector (e.g., HDMI, DisplayPort) and a matching CRTC (Cathode Ray Tube Controller, the hardware block that scans data out to the connector).
Configure, build, and load a custom virtual graphics driver.
