iGPU / APU use case
Drive graphical apps and browsers with no display using Xvfb, and let the integrated GPU do the rendering instead of the CPU.
Xvfb provides the virtual display, but it renders on the CPU (llvmpipe). Chrome can render straight on the Intel GPU through ANGLE (--use-angle=vulkan --ignore-gpu-blocklist), under Xvfb or headless: about 20× faster WebGL in our measurements.
Ideal for Selenium, Playwright or Puppeteer in CI: launch real browsers and run your E2E suites reproducibly.
