Thanks for the updates on this as I"m currently looking at updating the farm to a fresher flavor of Linux. My antique server is running 16.04 on most of the blades and have been updating most of them in prep for WCG pandemic project. These will not have GPU in them and most do not have a GUI but hoping new kernels will support this older hardware. I hope you can get it figured out for your pharm as I look forward to this working well again. I wish the GPU support was as simple as it was on Linux mint and AMD drivers.
