The answer to both questions is yes. You can use it headlessly, but you still have to run an X server on the GPU-- a headless X server. Search the archives for several e-mails on how to do this, or maybe someone else will chime in with tips. My understanding is that it just involves the right edits to xorg.conf to make Xorg not look for a physical display. There is currently no way to access the GPU except through an X server, which is why we have to run one on the server. At one time, Sun had a technology called "GLP" that allowed fully headless access to a GPU without going through an X server. It used a GLX-like API to achieve this. It never made it onto any platform other than SPARC, however, and I think nVidia's position is that people should just use a headless X server to accomplish the same thing. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
