When following the instructions of the tutorial http://wiki.ros.org/stereo_image_proc... , I am unable to see disparity images. All commands run without errors, and I have fixed the bag, but the windows 'left' 'right' and 'disparity' are empty desktop.

The same issue occurs with my own cameras.

I am running Ubuntu 16.04 and ros Kinetic, and I found this issue on all of my computers : two raspberry pi 3 on Mate and an Oracle VM on Xubuntu.

[EDIT] However the tutorial works in a VM with Indigo and Ubuntu 15.04
