   1. Install libdrm, kernel headers, and drm_info (or build drm-tip examples).
   2. Run drm_info and parse output (connectors, encoders, CRTCs, planes).
   3. Build and run kmscube or modetest (from libdrm/tests) to modeset a buffer to a display.
   4. Modify kmscube to change mode timings or pan a framebuffer and recompile.
