I am new to X-Windows/Linux programming, so this is probably a dumb question, but…
I am working on an GPGPU type application that only needs a valid GL context. I don’t actually need visible rendering window. The example GLX based apps I have seen call XOpenDisplay to connect to the X-Server. Is this necessary to get a GL context? This app is going to be hard real-time and I am concerned about performance. Will the X-Server cause unpredictable delays?
