    Hello all,

    I’ve installed the most recent sandbox software (as of today 22 October 2016: VRUI 4.2, Kinect 3.2, SARndbox 2.2) on a Core i7 laptop running Ubuntu 14.04. Kinect and the digital elevation model all run fine, however the water simulation is not running. I suspect this to be an issue with the graphics card driver.

    The graphics card is an AMD Radeon M7 (8670M) series with an open source driver. A proprietary driver is apparently not available.

    When running the DEM I can call on the water simulation statistics and this will show a framerate rapidly changing around 30 fps. I take this to mean that the simulation is running. However, no water appears and the terminal window gives a persistent error message at what looks to be around 30 times a second as well. It refers to a GL error.

    Does anyone have advice?

    What is the GL error that you receive?
