Hands On Projects For The Linux Graphics Subsystem Access

Hands-On Projects for the Linux Graphics Subsystem

Below is a progressive, practical set of projects—ranked from beginner to advanced—designed to teach you the Linux graphics stack (kernel DRM/KMS, Mesa, Gallium, Wayland, X11, EGL/GBM, Vulkan, GPU drivers, compositor internals). Each project includes objectives, prerequisites, step-by-step tasks, expected learning outcomes, suggested tools, and checkpoints. Assume a modern Linux distribution with developer tools installed (gcc/clang, meson/ninja, git, pkg-config, libdrm, libwayland, libxkbcommon, libinput, Vulkan SDK optional). Adjust for your distro.

Goal

Modify a simple Wayland client (e.g., weston-simple-shm) and trace round-trip from client writev() to kernel DRM atomic commit. Hands On Projects For The Linux Graphics Subsystem

Level 3: Kernel Space (DRM & KMS)

This is the core of the Linux graphics architecture. The Direct Rendering Manager (DRM) is the kernel subsystem that manages GPU hardware. Hands-On Projects for the Linux Graphics Subsystem Below

How to use this guide

• Work projects in order: foundational projects build knowledge for later ones.
• Aim for one small commit per checkpoint; keep notes and git branches.
• Use a disposable test environment (VM, secondary machine, or separate user) for kernel and driver work.
• When modifying kernel/driver code, follow your GPU vendor’s contributor docs and abide by licensing.
