GPU Rendering

[Nepenthes-zlc]

I want to know if I can render by Virtual without display manager. In fact, my device don't have GDM and lightgdm

You don’t need a display manager. Create a virtual X server, start VirtualGL’s GLX bridge, and run the simulator with GPU rendering.

1. Start a virtual X server with e.g. export DISPLAY=:1 and Xvfb :1 -screen 0 1280x1024x24 &
2. Load NVIDIA + GLX: ensure NVIDIA driver and libGL are available on the node.
3. MINESTUDIO_GPU_RENDER=1 python -m minestudio.simulator.entry
   I am not familiar with this since I always use CPU rendering.
