We tried to use the latest driver on Amazon EC2 GPU instances, which have GRID K520, and got the following:
WARNING: The NVIDIA GRID K520 GPU installed in this system is supported
through the NVIDIA 367.xx legacy Linux graphics drivers. Please
visit http://www.nvidia.com/object/unix.html for more information.
The 375.26 NVIDIA Linux graphics driver will ignore this GPU.
So are we stuck using X11 with this hardware? Disappointing.
