Try to recompile libfreenect2 and check if OpenGL is active

Check libfreenect2 README.md file:

    If you have Intel GPU, there is a serious GLSL bug with `libgl1-mesa-dri`. You are recommended but not required to update it to >=10.3 or newest using later releases or xorg-edgers ppa.

1. OpenCL dependency
  * OpenCL ICD loader: if you have `ocl-icd-libopencl1` (provides libOpenCL.so) installed, you are recommended but not required to update it to 2.2.4+ using later releases. Early versions have a deadlock bug that may cause hanging.
  * AMD GPU: Install the latest version of the AMD Catalyst drivers from https://support.amd.com and `apt-get install opencl-headers`.
  * Nvidia GPU: Install the latest version of the Nvidia drivers, for example nvidia-346 from `ppa:xorg-edgers` and `apt-get install opencl-headers`. Make sure that `dpkg -S libOpenCL.so` shows `ocl-icd-libopencl1` instead of nvidia opencl packages which are incompatible with `opencl-headers`. CUDA toolkit is not required for OpenCL.
  * Intel GPU (kernel 3.16+ recommended): Install beignet-dev 1.0+, `apt-get install beignet-dev`. If not available, use this ppa `sudo apt-add-repository ppa:pmjdebruijn/beignet-testing`. Do not install `beignet` which has version 0.3.
