Ubuntu - OSVR Tracker Viewer Screen Goes Blue
Problem
Running Tracker Viewer in Ubuntu 14.04 displays a Blue Screen when HMD connected to OSVR Server. This is caused by incompatibilities with later versions of OpenSceneGraph past 3.4.x
Details
When running Tracker Viewer without the HMD connected but the OSVR Server running, the program draws the grid with axis. The mouse works to rotate around the axis.
However, if I start Tracker Viewer WITH the HMD connected, the grid and axis display for about 1/2 a second and then blue is drawn on the screen and nothing else can be seen.
Using head from OpenSceneGraph (which is the latest version). This might be the problem.
