Headless Chrome can utilize the local machine's GPU, at least in some circumstances. This capability is useful for Continuous Integration setups, running web workloads server-side, and in other scenarios.
With headless Chrome, pass the command line argument --enable-gpu to disable forcing software rendering. This defers to Chrome‘s default OpenGL driver autodetection, which on Linux requires that X display is available (i.e. X11 server is available and DISPLAY env var is set accordingly). While the default auto-detection doesn’t seem to work without X11, forcing Vulkan backend (--use-angle=vulkan) have been found to work at least on some Linux configurations.
Linux NVIDIA users may find Server Side Headless Linux Chrome With GPUs helpful.
