Hi, I'm trying to run some Python software for delivering visual stimuli for neuroscience experiments, PsychoPy, on a UDOO quad. I have heard that the OpenGL libraries used by PsychoPy cannot be run with OpenGL ES , so I was hoping the UDOO's OpenGL full version support would be able to run this. When trying some example scripts however, I get an error like: libgl error: UNIX signal already caught This is an OpenGL problem, right? I've tried this on several Linux formulations (UDOObuntu, Linaro 12.04 LTS) and I still get the same error. Any ideas on what the problem is, or pointers on how to remedy?
