So it does work but is way too slow for our purposes (~6 mins for a frame). So we started looking into headless with GPU. So far, if I start a desktop then switch to headless it works fine but if I start in headless mode and never load a desktop I can't get it working. Xorg is already running, lightdm is running, anything else I need for the graphics context to initialize correctly? (Sorry, this probably isn't the best forum for a question like this and if a mod would rather me look elsewhere, just let me know).
