I am using the 1.5.1 branch + processing 1.5.1 on ubuntu 12.10 32 bit, NVIDIA driver 304.88 (Quadro K5000). The ActiveStereoTest example does not appear to work. It just shows the perspective of one eye and the IR emitter does not even light up. The following error is shown in the console:
OpenGL error 1282 at top endDraw(): invalid operation
cheers,
Rob
