Successfully running container with nvidia drivers but unable to use those drivers

[Redshift92]

Good evening,
I am successfully running a container through nvidia-docker, here the output of nvidia-smi inside the container:

but when I try running glxgears I get:

lorenzo@a72ba8cced9f:/$ glxgears 
libGL error: pci id for fd 4: 8086:191b, driver (null)
libGL error: No driver found
libGL error: failed to load driver: (null)
libGL error: failed to open drm device: No such file or directory
libGL error: failed to load driver: i965

despite:

lorenzo@a72ba8cced9f:/$ echo $PATH
/opt/ros/indigo/bin:/usr/local/nvidia/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
lorenzo@a72ba8cced9f:/$ echo $LD_LIBRARY_PATH
/opt/shared/catkin_ws/devel/lib:/opt/ros/indigo/lib:/usr/local/nvidia/lib:/usr/local/nvidia/lib64

Thank you in advance

Unfortunately, OpenGL is not officialy supported for now (see #11). Only CUDA is supported.
